If this product is to be mounted in an equipment rack, rear support should be provided.18. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S. Government’s Occupational and Health Administration (OSHA) has specified the following permissible noise level exposures: Duration Per Day In Hours Sound Level dBA, Slow Response

⁄4 or less 115 According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.

Series power amplifiers feature a unique amplification architecture providing a host of user benefits including simplified operation and use in multiple applications, as well as unsurpassed sonic quality and flexible power. The CM 2204-AB (US model)/CM 2204-DV (European model) and CM 2208-AB (US model)/CM 2208-DV (European model) are easy to set up and operate. Housed in a lightweight-but-rugged 16-gauge steel chassis, multi- load architecture allows low impedance or 70 Volt operation without so much as flipping a switch. Each channel outputs 220 Watts (70V or 8 Ohms, or 160 Watts into 4 Ohms) for flexible system configuration, while front-to- side cooling delivers low mains current draw, ensuring efficient operation in a 2U rack space. CM Series products comprise four-channel (CM 2204-AB/DV) and eight- channel (CM 2208-AB/DV) units (channels are independent). A host of applications benefit from the use of multiple channel amplification, including bars, clubs and restaurants; video conferencing systems; hotels and motels; industrial installations; and retail stores, among others. One amplifier for multiple applications provides a cost-effective solution, expansion opportunities and unparalleled flexibility. The CM Series has numerous circuit protection features, including: Automatically reduces gain at the onset of clipping to prevent amplifier and load damage. Monitors load current to protect against overloading. Gradually increases gain when the amplifier is turned on, preventing abrupt turn-on level. Short circuit, DC voltage, comprehensive thermal management, current in- rush turn-on/off transient and sub/ultrasonic input. Some of the protection features are described in more detail later in this manual but please note that improper use can be dangerous to the user as well as the unit. These amplifiers are very high-powered and can produce high voltages and sizable currents. Always use safe operating techniques when operating these amplifiers but we also encourage you to read this manual thoroughly.

Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials. Should you ever need to ship the unit back to Crest Audio, one of its offices, service centers or the supplier, use only the original factory packing. If the shipping carton is unavailable, contact Crest Audio to obtain a replacement. Mounting The CM

Series power amplifiers will mount in standard 19" racks. Cooling Requirements The CM Series power amplifiers use a forced-air cooling system to maintain a low, even operating temperature. Air is drawn into the amplifier via a fan located in the front of the unit and courses through the cooling fins of the heat sink. The air then exits through the sides of the chassis. If the heat sinks get too hot‚ a sensor circuit will activate the protective muting system to protect the amplifier. When the internal temperature reaches a safe level‚ the amplifier will automatically return to normal operation. It is important that both the front and the side of the unit have adequate space to allow the cooling air to enter and escape. If the amp is rack mounted, do not use doors or covers on the front of the rack; the intake air must flow without resistance. If you are using racks with closed backs, make sure that there is one (1) standard rack space opening for every three mounted power amplifiers. If not rack mounted‚ allow 6" of clearance on all sides. 8W I R E G A U G E C H A R T Cable Length (In Feet) Stranded Wire Gauge (AWG) Power Loss into 8 Ohms (%) Power Loss into 4 Ohms (%)

Operating Precautions Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty. Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. Also, as an extra precaution, turn down the attenuators before powering up. It is always a good idea to have the gain controls turned down while powering up to prevent speaker damage if there is a high signal level at the inputs. Whether you buy or make them, use good-quality connections, input cables and speaker cables, along with good soldering technique, to ensure trouble-free operation. Most intermittent problems are caused by faulty cables. Consult the Wire Gauge Chart (below) to determine proper gauges for various load impedances and cable lengths. Remember that cable impedance robs amplifier power in two ways: power lost directly to resistance (I2R loss), and by raising the total load impedance.

Front Panel (1) Power Indicator The green LED indicates that AC power is supplied to the unit and the power switch is ON. (2) Signal Indicators Green LEDs indicate significant signal presence on that channel output. The Signal Indicator illuminates only when an output signal is 1 Watt or higher (at 70V). Therefore, it is possible to have an acceptably strong signal without the Signal Indicator illuminating. (3) Clip Indicators The Clip Indicator LED illuminates yellow when the CM 2204/CM 2208 experiences excessive voltage or current into the load. When the amplifier output reaches its limits, Active Clip Limiting (ACL

) will attempt to compress the signal, causing the Clip LED to illuminate momentarily. An over-current condition is more likely to occur with low impedance speakers. For more information on clipping, see the IGM

and ACL descriptions on page 7. Upon continuous clipping, the unit will go into Protect (see # 4 below) for one second and check the clipping condition. If the unit experiences a persistent clipping condition, the unit will go into Protect permanently for that channel, indicated by the Protect LED blinking steadily. In this case, to bring that channel out of Protect mode, it is necessary to cycle power by turning the unit OFF and then ON. If the Protect LED continues to blink after power is restored, it is likely that the channel is damaged and service to the unit is required.

1 2 3(5) AC Power Switch CM Series power amplifiers have a standard AC switch on the front panel.

Warning: The power switch does not break both sides of the

line and under certain conditions hazardous energy can be present when the switch is in the OFF position. (6) Cooling Air Vent The CM Series is designed to operate under extreme conditions. The front-panel design features a duct that allows air to be drawn in by the fan, circulated through the removable filter (for cleaning) and finally dispersing out the sides of the unit. The openings on the front and sides of the unit should never be blocked. It is recommended that the removable filter be cleaned with compressed air. Front Panel

(4) Protect Indicators Upon powering up the unit, the Protect LEDs illuminate momentarily and then turn off one channel at a time and then remain off. During normal operation, an over-current condition can occur if the amplifier is being overdriven to the point where clipping is continuous or from a short circuit in the speaker output. The Protect LED will illuminate red when one of these conditions occurs. The internal temperature of CM

Series amplifiers is 65º celsius. Should the unit exceed this temperature, the amplifier will go into thermal protect mode (generally, this would only occur if the internal fan fails). If the amplifier has a thermal fault condition‚ all LEDs will illuminate. When the amplifier cools down, the unit will restart automatically.

Rear Panel (7) AC Mains Power Receptacle This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for the intended operating voltage is included in the carton. The mains cord should be connected to the amplifier before connecting to a suitable AC outlet. AC Mains Cord The mains cord supplied with the unit is a heavy duty‚ three conductor-type with a conventional 120 VAC plug (230 VAC European) with ground pin. Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a ground pin‚ a suitable grounding adapter should be used and the third wire should be properly grounded. NOTE FOR UK ONLY: If the colors of the wires in the mains lead of this unit do not correspond with the colored markings identifying terminals in your plug, proceed as follows: (1) The wire that is colored green and yellow must be connected to the terminal marked by the letter E, or by the earth symbol, or colored green or green and yellow. (2) The wire that is colored blue must be connected to the terminal that is marked with the letter N, or colored black. (3) The wire that is colored brown must be connected to the terminal that is marked with the letter L or colored red. (8) Channel Outputs The outputs are two-pin Phoenix connectors. Connect the loudspeaker sys- tem to the respective positive (+) and ground (-) terminals as indicated on the unit. An exception is when the unit is in Bridged Mode, whereupon a speaker is connected to two positive terminals on the outputs of two chan

Ch 4 (9) Channel Inputs The inputs are balanced, three-pin Phoenix connectors. Connect the incoming signals to the respective positive (+), negative (-) and ground ( ) terminals as indicated on the unit. Channel input sensitivity is 0dBu (0.775V) when the 0dB gain setting is selected. This equates to a gain of 90.3x. Gain can also be decreased to x40 with the gain setting switch (see # 12 Gain Select). If using bridged, see the Bridged Mode section. Input Connections The Phoenix connectors are wired as: Pin 1 is positive; Pin 2 is negative; and Pin 3 is chassis ground. Normally balanced inputs are wired using two-conductor shielded cable as shown in the following diagram. For un- balanced (single-ended) inputs‚ the single conductor is wired to Pin 1 and the shield is connected to Pins 2 & 3 as shown in the following diagram.

(11) Stepped Attenuators Each channel input features a 21-position stepped attenuator ranging from negative infinity to 0 dB. The “halfway” position of the stepped attenuator is -6 dB, as indicated on the unit. (12) Gain Select An individual Gain Select is available on each channel input. This two- position switch can be set at 0 dB in the bottom position and x40 in the top position. (13) Circuit Breaker If the circuit breaker pops, turn the unit OFF and let sit for one minute and then turn back ON. If the circuit breaker pops a second time, the unit may be damaged and should be returned to a Crest Audio dealer for servicing. (10) High-Pass Filter This two-position switch provides enabling or bypass of a high-pass filter, which is available on each channel input. In the top position (enabled), the high-pass filter cutoff is 70 Hz. In the bottom position (disabled), the input frequency range is extended down to 1 Hz. The top and bottom positions of the high-pass filter are indicated on the unit by a sloped line and a flat line, respectively.15 Bridged Mode A pair of amplifier channels may be bridged together to make a single output with a power rating equal to the sum of both channel power ratings at twice the load rating of a single channel. In other words‚ bridging two amplifiers rated for 160 Watts into 4 Ohms will produce 320 Watts into 8 Ohms. In Bridged Mode‚ the channels operate at opposite polarity from each other so that one channel pushes and the other pulls equally. This mode sends the input signal to one channel and the same signal with its polarity reversed to the other channel for any two channels (1/2, 3/4 on the CM 2204-AB/DV or 1/3, 2/5, 4/6, 7/8 on the CM 2208-AB/DV). For example, to bridge channels 1 and 2, connect the input signal to the channel 1 input connector using the standard connections (see # 9, Channel Inputs in Back Panel section). On channel 2 however, reverse the positive and negative input connections so that the positive (+) connector is connected channel 2’s negative (-) receptacle and the negative input connector (-) is connected to channel 2’s positive (+) receptacle. Both channel level controls (in this example‚ 1 & 2) MUST be used to control the signal level and both MUST be set at the same position. Wire Connections + input GND inpu

cations. Low-Z This mode allows each output of the channel pair to drive a 4 or 8 Ohm loudspeaker load. Use Bridged Mode (See Bridged Mode section) to deliver the power of both channels to a single 8 Ohm load such as a subwoofer. 70V This mode allows each output of the channel pair to directly drive a 70 Volt constant-voltage audio distribution system. Use the Bridged Mode (See Bridged Mode section) to deliver the power of both channels to a 140 Volt constant-voltage audio distribution system. 100V/50V The output of the CM 2204-AB/DV and CM 2208-AB/DV can be converted to 100V or 50V with the optional CMX4-50/CMX4-100/CMX8-50/CMX8- 100 accessories, respectively. Outputs in Bridged Mode The loudspeaker load is connected only to the designated positive (+) output terminals of the bridged channels. NEVER ground either side of the loudspeaker load cable when the amplifier is in Bridged Mode as both sides are “hot.” If an output patch panel is used‚ all connections must be isolated from each other and from the panel. When using the low-Z output‚ the minimum nominal load impedance in Bridged Mode is 8 Ohms; this is equivalent to driving both bridged channels at 4 Ohms. When using the 70 Volt output‚ the bridged output is 140 Volts and the minimum load imped

ance in Bridged Mode is 50 Ohms. Driving loads of lesser impedance may activate the protection circuits. See Output Modes section for more infor

mation. Regardless of operating mode‚ NEVER connect the amplifier outputs together. Output voltages greater than 120 V RMS are available between the bridged terminals. CLASS 3 wiring must be used in accordance with national and local codes to connect the loudspeaker system. The loudspeaker output connections of this amplifier are hazardous when live and present a shock hazard when they are energized. Take the following precautions:

1. Do not touch any bare wires that are connected to the loudspeaker

2. Use insulated loudspeaker cables and touch-proof connectors on the

3. Do not attempt to make connections to the output connectors or the

loudspeaker connectors when the amplifier is turned ON.

4. Double-check all connections and make sure there are no exposed wires

or connectors before turning the on amplifier.

5. Make sure there are no frayed cables or wires and that all connections

are tight and secure every time before turning the amplifier on.

6. External wiring connected to these terminals requires installation by a

trained person or the use of ready-made leads or cords. Note: Caution:
