[. . . ] CX168 8-Channel Installed Sound Professional Audio Amplifier User Manual *TD-000095-00* TD-000095-00 rev. C 1 IMPORTANT SAFETY PRECAUTIONS & EXPLANATION OF SYMBOLS CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER. REFER SERVICING TO QUALIFIED PERSONNEL. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous" voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in this manual. The lightning flashes printed next to the OUTPUT terminals of the CX168 amplifier are intended to alert the user to the risk of hazardous energy. Output connectors that could pose a risk are marked with the lightning flash. Make all connections with amplifier turned off. WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. This amplifier has a serial number located on the rear panel. [. . . ] When turned fully counterclockwise, gain is fully reduced and no output signal will be present. When turned fully clockwise, the voltage gain of the amplifier is +26dB and the output signal will potentially be full strength (provided the input is fully driven). Surrounding the Gain control, the power attenuation level is shown in dB. To operate the gain control, rotate the control's knob so that the desired level is achieved. Be sure not to use large screwdrivers as it is possible to damage the gain control by applying excessive torque. Gain controls are sensitive, electronic components and should be treated with care. Location of gain controls on the front panel of the CX168 Each channel pair's gain controls and indicator LED's are grouped together as shown, right. The channels are paired in the following manner: Channel Pair #1Channel Pair #2Channel Pair #3Channel Pair #4Ch. 8 As detailed in the `Setup' section of this manual, channels can only be paralleled and bridged within their channel pair. Example- Channel 3 can be bridged with channel 4 only; it can not be bridged with any other channel. Typical channel-pair control and indicator group on the CX168 The dB markings around the gain controls are attenuation. If the gain control is set at the 7dB attenuation position, then the voltage gain of the amplifier is 19dB (26dB - 7 dB). Typical gain control showing attenuation level markings and LED's for the channel. Note that there is only one BRDG (bridge) and one PAR (parallel) indicator per channel pair. 18 OPERATION: GAIN CONTROL SECURITY PLATE Gain Control Security Plate After final gain adjustments have been made, the gain controls can be covered with a security plate. This easy-to-use security plate makes it difficult for others to adjust the gain. This may be desirable in instances where the gain controls should not be tampered with. ventilation slots, insert into the slot and then slide the panel fully right, locking it in the slot. 2. Orient the panel as shown and slide the right end of the plate under the screw. 4. Make sure the LED's are visible, then tighten the screw with the hex key. Do not over tighten! When properly installed, the security panel will still allow you to monitor all the channel status LED's and power LED. The amplifier front panel will look like the illustration, right, after installing the security plate. 19 OPERATION: USING THE QSC DATAPORT CONNECTIONS DataPort Connectors QSC's DataPort equipped amplifiers offer operators of larger audio systems a high degree of system monitoring and operation from remote locations. A system operator in a sports complex might be located hundreds of yards (meters) from the actual amplifiers, making `normal' control and monitoring of the system difficult, at best. By integrating QSC's DataPort-equipped amplifiers with QSC's DataPort accessories, a dependable and robust control and monitoring solution can easily be implemented. The DataPort is used for connection to optional QSC DataPort accessories. DataPort accessory devices can provide remote cinema monitoring, DSP, filter and crossover functions. [. . . ] · The design of the amplifier eliminates internal hum fields, but external transformers or other magnetic devices may cause hum. Move cabling and signal sources to identify "hot spots" in the system; then avoid those spots. Another common source of magnetic fields are "wall warts" or pluggable transformers; keep input wiring away from them. Magnetic field from power supplies in equipment can induce hum into cabling that is located in the field. If hum is a problem, try relocating cabling so that is away from power supplies, transformers and other magnetic field producing devices. 29 SPECIFICATIONS OUTPUT POWER in watts FTC: 8 ohms per channel (20 Hz. -20 kHz. , 0. 05% THD) 4 ohms per channel (20 Hz. -20 kHz. , 0. 1% THD) CX168 90 130 120 180 (100 watts, all channels driven) (140 watts, all channels driven) EIA: 8 ohms (1 kHz, 0. 1% THD, 1 channel driven) 4 ohms (1 kHz, 0. 1% THD, 1 channel driven) Bridged Mono: 16 ohms, 20 Hz. -20 kHz. , 0. 1% THD 8 ohms, 20 Hz. -20 kHz. , 0. 1% THD DYNAMIC HEADROOM 180 260 2 dB at 4 ohms DISTORTION SMPTE-IM Typical 20 Hz. -20 kHz. , 10 dB below rated power Typical 1 kHz.
