User manual PEAVEY CS 1200H

[. . . ] CS®1200H Operations Manual power amplifier For more information on other great Peavey products, go to your local Peavey dealer or online at www. peavey. com 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 persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock -- DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] The input attenuator controls (one for channel A, one for channel B) located at the front panel adjust gain for their respective amplifier channels in all modes. See the specifications at the end of this manual for standard voltage gain and input sensitivity information. When operating in the bridged mode, the channel A attenuator controls the signal. See the section on Bridged Mono Operation for more information and precautions. Front Panel Indicators The CS 1200H features four front panel discrete LED indicators per channel: ACTIVE , DDT , TEMP and DC . These LED indicators inform the user of each channel's operating status and warn of possible abnormal conditions. This amplifier also features two 10-segment bar graph indicators per channel: SIGNAL . Signal LED (3) This LED is at the bottom of the bar graph display and lights when its channel produces an output signal of greater than 2 Volts RMS or 50 mV input with a 0 dB attenuation of the front panel knobs. It is useful in determining whether a signal is reaching and being amplified by the amplifier. The 10segment graphs indicate the level of signal present. DC LED (4) The DC LED lights to indicate that the channel's output relay is open, disconnecting the speaker(s) when the amplifier senses a DC voltage or subsonic high level signal at its output. Temp LED (5) The Temp LED lights to indicate that the channel's output relay is open, disconnecting the speaker(s) due to an overheating condition. Once the channel temperature has returned to safe operating conditions the LED will turn off and the speaker(s) will be reconnected. DDT Active LED (6) Illuminates when DDT Compression is taking place. With the Enable/Defeat switch in the Defeat position, the LED indicates when clipping distortion is occuring. 7 Active LED (7) The ACTIVE LED indicates that its channel's output relay is closed and the channel is operational. In Bridge Mode, the Channel B LED goes off. Air Intake Vent (8) Cool air enters the amplifier here and exhausts through the rear vents. Any restriction or blockage could cause excessive operation temperatures and the unit could shut down. Rear Panel 16 15 14 13 12 10 11 17 18 9 17 18 19 20 19 21 Air Exhaust Vents (9) These vents provide an exhaust path for the hot air from the heatsinks. Any restriction or blockage could cause excessive opertion temperature and the unit could shut down. Mode Select Switch (10) The rear panel MODE Select Switch determines whether the amplifier is in stereo or bridged mono mode. DDT Switch (11) This switch is used to either Enable or Defeat the DDT compressor. It is recommended to leave the DDT compression enabled at all times to protect your speakers from damage square waves. Channel Input (12) This input features a combo connector that will accept a standard three-pin male XLR, 1/4" (6. 3 mm) TRS (Tip-Ring-Sleeve), or 1/4" (6. 3 mm) mono plug. An electronically balanced input is available via XLR and 1/4" TRS use. The unit is internally wired for the following: Input (+) (-) GND XLR Pin 2 Pin 3 Pin 1 TRS Tip Ring Sleeve 8 Crossover Adjustment Knob (13) The CS 1200H is equipped with two independent, two-way crossovers adjustable from 40 Hz to 300 Hz. These crossover frequencies are appropriate for use with a subwoofer system. The output of these crossovers is selected by the Amp Function switch and connected to the corresponding amplifier channel. Frequencies above the knob setting will be connected to the corresponding channel when the Amp Function switch is in the HIGH PASS position. Frequencies below the knob setting will be connected to the corresponding channel when the Amp Function switch is in the LOW PASS position. The FULL RANGE position bypasses the crossover. Amp Function Switch (14) The rear panel Amp Function Select Switch determines whether the associated channel is connected for full range operation or to the crossover high frequency or low frequency outputs. Low Cut Switch (15) The LOW CUT switch is a recessed push switch used to defeat or engage the LOW CUT filter. Pushing the switch to the in position will engage the filter. Low Cut Adjustment Knob (16) The CS 1200H is equipped with two independent low frequency filters. [. . . ] 8.
