The CE-2 builds on the legacy of the CE-1 with reduced features: mono output instead of stereo, no vibrato mode, no integrated power supply, no level and no intensity controls. The CE-2 has higher input impedance and boosted mid frequencies, both arrangements very suitable for electric guitars. Roland stopped marketing the CE-2 in 1982, however still produced until 1990. There are basically 3 versions of the pedal: Some early stand-alone stompboxes like Vibra-Chorus and Uni-Vibe by Shin-Ei were released in 1960s, creating some degree of phase shifting or chorus modulation. The CE-2 follows the same tonal response. The usual delay times are around 5 to 50ms and LFO oscillating frequencies are up to 20Hz. CE-2 uses triangle LFO waveforms. There are several possibilities: Hearing both signals together the chorus effect is created. The input and output circuits use the dual op-amp uPC4558C IC, while the LFO is implemented with the help of a TL022LP op-amp. Some additional active filtering is applied using Sallen-Key transistor stages. The effect response is commanded using two controls: The top of the board contains all the pads to attach the cables to be connected to the jack connectors, potentiometers, and the footswitch. It also carries other benefits like the number of components used in the pedal and using a light indicator and a power-on LED at the same time. The JFET Bypass Switch enables two possible toggle configurations: The VR 3 potentiometer is able to finely trim the 4.5 voltage: sometimes due to the loading of all stages, the 4.5 voltage might suffer some offset, the BBDs are sensitive to the bias, adjusting VR3 will bring maximum clean headroom. The 9V regulated line will bring the supply for the Bucket Brigade Stage, rejecting high-frequency harmonics which are especially harmful in BBDs signal processing due to the clocking noise of the MN3101 clock driver. This pedal was originally designed for an external 12V ACA supply adapter. The series resistor R53 and diode D5 between the minus input on the power jack and ground are used to reduce the internal voltage supply. The voltage drop over the resistor and diode will under-power the pedal making the power-on LED glow faintly. One easy solution is to use a daisy chain cable together with another standard pedal. The link between the two pedals will short the resistor-diode circuit and the pedal will receive full power. It also separates the guitar from any pedal DC potential, protecting the pickups in case of circuit failure. But applying the same filtering to the delay signal, the output signal will reduce any hiss acquired via the delay path. Boss CE-2 uses the op-amp inverting architecture. It is also implemented over the 4558 dual op-amps and designed to attenuate the magnitude of the high frequencies with respect to the mid-low frequencies. This filter takes the unnatural sounding pre-emphasized audio and turns it back into its original response. These are generated at integer multiples of the sample rate. The ideal filter specification is the same as that for the anti-aliasing filter. In this way, the input signal is bandlimited to prevent aliasing. The cut-off frequency can be calculated as: The output signal must be bandlimited, to remove the clock noise and prevent aliasing (meaning Fourier coefficients being reconstructed as low-frequency waves, not as higher frequency aliases). The cut-off frequency can be calculated as: After the delay stage, slightly more bass pass through the circuit. At the same time, a Low-Frequency Oscillator (LFO) is needed to drive the MN3101 in order to generate the variable delay time which is the gist of the chorus effect. It is used to discharge the C 22 47pF timing capacitor, which is charged through the R 38 150K resistor. Indeed, Q 5 together with the MN3101 will oscillate by itself at a constant frequency without Q 4 and its associated components. The cycle repeats at an ultrasonic rate. Immediately after C 22 discharge, the diode D1 is needed to isolate the output of Q4 transistor.As the LFO cycles, the delay time goes up and down and therefore the delayed audio pitch slightly shifts up and down. Some ticking can be mixed with the audio when the LFO produces the rising or falling edge of a square wave and there is a very sudden surge in the current. This simple circuit provides a variable frequency triangular waveform whose amplitude is also variable. The oscillation frequency can be calculated following the formula of the Triangle Oscillator by Ron Mancini: The action of VR2 will modify the steepness of the ramp and therefore the amplitude or depth at a fixed frequency.

It sums the left and right block inputs into mono, so use caution as stereo cancellation may occur.In 2018 Boss released its DC-2W Dimension C pedal, an update which is part of the Waza Craft Series. YouTube However I highly recommend using the Dimension Type as it sets the correct base algorithm, LFO type, delay time, phase, etc., etc. as well as turning on the Dimension Processing. The Dimension D is really just a typical chorus. At the output, however, some special processing occurs that gives that unique sound. The unit itself has four switches. These switches set the rate and the depth as well as turn on the boost mode. The depth is actually reduced in modes 3 and 4 to compensate for the higher rate. In the Axe-Fx this is done automatically when Auto Depth is on. The LFO is a triangle wave and is 180 degrees out of phase between channels. The Dimension Mode parameter has three settings: Low, Medium and High. Low: Dry EQ off, boost off. Med: Dry EQ on, boost off. High: Dry EQ on, boost on. The Low setting has no equivalent on an actual Dimension D since the dry EQ is always active. The Dimension Type sets the LFO type, phase, Auto Depth, Hi Cut, etc., etc. and sets the Dimension Mode to Medium. The Rates are given above. I've found a Depth of around 25 to be a good starting point. Increase or decrease to taste.You can create this effect by using a 100 wet Chorus (no dry signal).As documented here, the Vibrato mode of the venerable Boss CE-1 depends on a variable Mix setting.The original devices have been discontinued, but there are a few replicas.

Demonstration by Camilo Velandia The delay lines are BBD emulations.Placed PRE, the block operates as a pedal on a traditional pedalboard.If you're collapsing the signal to mono after the Chorus block, the wet side will completely cancel and you'll hear no chorus at all. The Empress allows the user an almost infinite number of flavours by adjusting the “voice” control - an innovation never before offered and only available in the Empress. As well as Andy Summers, folk like Jon Hudson (Faith No More), Sigur Ros, Paul Stacey (Oasis) and Terry Lawless (U2) consider the Empress Chorus to be a favorite. The 4 knobs (manual, depth, rate and resonance) allow the users to shape the sound as desired -- from dynamic jet-plane effects to short delay, chorus and vibrato sounds.

Hydraulic flows based on 4.48 C.I.R. motor requirements at 2600 psig average.While there are standard safety rules, each situation has its own peculiarities that cannot always be covered by rules. Therefore with your experience and common sense, you are in a position to ensure your safety. Lack of attention to safety can result in: accidents, personal injury, reduction of efficiency and worst of all - Loss of Life. Watch for safety hazards. Correct them promptly. Use the following safety precautions as a general guide to safe operation: Do not attempt to remove any compressor parts without first relieving the entire system of pressure. Do not attempt to service any part while machine is operating.Periodically check all safety devices for proper operation. Do not play with compressed air. Pressurized air can cause serious injury to personnel. Exercise cleanliness during maintenance and when making repairs.Do not install safety devices other than authorized BOSS INDUSTRIES replacement devices. Close all openings and replace all covers and guards before operating compressor unit. Tools, rags, or loose parts must not be left on the compressor or drive parts. Do not use flammable solvents for cleaning parts. Keep combustibles out of and away from the Compressor and any associated enclosures. The owner, lessor, or operator of the Compressor are hereby notified and forewarned that any failure to observe these safety precautions may result in damage or injury. These decals must be affixed to the vehicle after it has been painted, trimmed, and undercoat, etc.The decals shall be placed so as to be clearly visible to the user and service personnel. (Figures 1 through 6.) Figure 1. To be placed on visor or dash near start-up procedure decal. Sometimes referred to as the separator element. CFM - Refers to the volume of compressed air being produced expressed as cubic feet of air per minute. LOAD CONTROLLER - Sometimes referred to as the engine speed control. OIL SUMP - The first stage of oil separation from compressed air. Also serves as reservoir area for compressor lubricant and sometimes referred to as the receiver tank. PSI - Refers to the operating pressure the system is set up at, expressed as pounds per square inch. SAFETY VALVE - A valve located on the oil sump which opens in case of excessive pressure. Sometimes referred to as the pop-off or pressure relief valve. SHUTDOWN SWITCH - Works in conjunction with a temperature and pressure switchgauges, sending a signal to stop the compressor power source in cases of high temperature or pressure. SIDE MOUNT PTO - Power take off gearbox that bolts to the side of the transmission. The PTO input gear with one of the gears in the vehicle’s transmission. The rotation developed by the engine drives the transmission which turns the PTO gear box and rotates the PTO output shaft, driving the compressor. ADAPTER GEAR ASSEMBLY: SIDE MOUNT PTO - The adapter gear assembly and the side mount PTO are assembled to the side of the transmission. Typically a PTO box installed on a manual transmission will require an adapter gear assembly in order to obtain the proper engine rotation required by the compressor. Most automatic transmissions utilize engine rotation PTO’s. Consult Boss Industries Inc. Components include a housing (stator), two screws (rotors), bearings, and bearing supports. Power from the engine is transferred to the male rotor through a drive shaft and gears in the gear housing. The female rotor is driven by the male rotor. There are four lobes on the male rotor while the female rotor has five roots. PRINCIPLES OF OPERATION In operation, two helical grooved rotors mesh to compress air. Inlet air is trapped as the male lobes roll down the female grooves, pushing trapped air along, compressing it until it reaches the discharge port in the end of the stator and delivers smooth-flowing, pulse-free air to the receiver. During the compression cycle, oil is injected into the compressor and serves these purposes: 1. Lubricates the rotating parts and bearings. 2. Serves as a cooling agent for the compressed air. 3. Seals the running clearances. LUBRICATION SYSTEM Oil from the compressor oil sump, at compressor discharge pressure, is directed through the oil filter, cooling system, and to the side of the compressor stator, where it is injected into the compressor. At the same time oil is directed internally to the bearings and shaft seal of the compressor. The oil-laden air is then discharged back into the sump. OIL SUMP Compressed, oil-laden air enters the sump from the compressor. As the oil-laden air enters the sump, most of the oil is separated from the air as it passes through a series of baffles and de-fusion plates. The oil accumulates at the bottom of the sump for recirculation. This valve acts as a backup to protect the system from excessive pressure that might result from a malfunction. When air is demanded at the service line, it passes through the coalescer which efficiently provides the final stage of oil separation. OIL RETURN LINE The oil that is removed by the coalescer accumulates at the bottom of the can and is returned through an oil return line leading to the compressor. MINIMUM PRESSURE ORIFICE The minimum pressure orifice is located at the outlet of the coalescer head and serves to maintain a minimum discharge pressure of 65 PSIG in operation, which is required to assure adequate compressor lubrication pressure. OIL FILTER The compressor oil filter is the full-flow replaceable element type and has a safety bypass built into it. COMPRESSOR COOLING SYSTEM (STANDARD) The compressor cooling system consists of an oil cooler remote mounted aerodynamically designed cooling pressure or a cooler mounted in front of the truck’s radiator. Oil temperature is controlled by a thermal switch or a valve located down stream of the oil filter. It is designed to be mounted inside the cab or in a protected area outside of the cab. Operate compressor within the discharge pressure limits as indicated in specifications section. HOURMETER The hourmeter records the total number of operating hours. It serves as a guide in following the recommended inspection and maintenance schedule. The hourmeter will only rum when there is pressure in the system. The switchgauge ensures safety shutdown in case of excessive operating temperatures, preventing compressor damage. ELECTRICAL AND SAFETY SYSTEM The BOSS compressor’s standard electrical system consists of a gauge panel; a remote mount 12 VDC fan package with fan switch and relay assembly (for standard cooling system only); and a resetable normally closed shutdown switch. These components are integrated together to provide a safety shutdown system that is activated when extreme high temperature or pressure conditions are present. When the temperature or pressure exceeds the maximum set parameter of the respective switchgauge a signal is sent to “trip” the shutdown switch from normally closed to open. This signal will then shut off the engine in vehicles equipped with a CABLE PTO or disengage the PTO in “HOT SHIFT” PTO applications. ELECTRONIC ENGINE INTERFACE Electronic engine interface for the compressor speed control incorporates several BOSS supplied electrical components that are chassis specific. A chassis specific wiring diagram and electrical components are supplied per the vehicle application data at the time of the order. It is located at the downstream side of the coalescer head and will automatically bleed the sump to zero pressure when the compressor is disengaged. Blow down time interval takes between 30 to 60 seconds. CONTROL SYSTEM The prime component of the compressor control system is the compressor inlet valve. The control system is designed to match air supply to air demand and to prevent excessive discharge pressure when compressor is at idle.
