User manual BIAMP MCA SERIES

[. . . ] 16) In order to comply with international safety requirements for operating temperature, clearance of at least 5cm or 1. 97" must be maintained between this device and other rack-mounted devices. This spacing will ensure that all exposed metal surfaces are safe to touch. 11) Only use attachments/accessories specified by the manufacturer. Explanation of safety related markings and symbols which appear on the outside of the apparatus. [. . . ] For best performance, first adjust the source signals for optimum (maximum) levels, then adjust the MCA Series Level controls for the desired volume. Signal / Peak Indicators: These 2-color LEDs indicate the signal level for each channel. Clipping can cause severe distortion, over-temperature conditions, and even loudspeaker damage. NOTE: Signal / Peak indicators will turn off during Temp / Fault condition (see Temp / Fault Indicators on pg. HPF: These DIP switches provide High-Pass Filters for the input channels. High-Pass Filters are used to eliminate unnecessary lower frequencies (12dB/octave @ 125Hz) for speech and distributed speaker applications. To assign a High-Pass Filter on an input channel, move the switch to the down position. CAUTION: To avoid output fault conditions, High-Pass Filters must be assigned on channels driving 25/70/100 Volt speaker systems (see Output below). Also, any other system equalization affecting frequencies below 125 Hz should remain flat or be used as cut-only. Bridge: These DIP switches allow adjacent channels to Bridge together in pairs, for a higher, combined output power (see Bridging on pg. Bridge disables the even numbered input, and applies the odd numbered input signal to both amplifier channels. To assign Bridge to a pair of channels, move the switch to the down position. Output: These screw terminals provide the speaker outputs from the channels. Connect the positive speaker line to the (+) terminal and the negative speaker line to the (-) terminal of the channel being used. NOTE: When using a pair of channels in 'bridged' mode (see Bridge above), connect the positive speaker line to the (+) terminal of the odd numbered channel and the negative speaker line to the (+) terminal of the even numbered channel. Output transformers for 25/70/100 Volt speaker systems are available as an option (installation instructions are included with the output transformers). Transformers (by model) are as follows: TDT50 = MCA 8050 individual channels (50 Watts) TDT100 = MCA 8050 bridged channels (100 Watts) TDT150 = MCA 8150 individual channels (150 Watts) TDT300 = MCA 8150 bridged channels (300 Watts) Remote Control: This 15-pin Sub-D (female) connector provides remote level & muting control of the input channels (see Remote Control on pg. NOTE: When using a pair of channels in 'bridged' mode (see Bridge above), apply Remote Control only to the odd numbered input channel. The AC Power Cord is for connection to three-prong grounded AC outlets.
