For unbalanced connection, wire high (+) and ground to both ( ) & (-). NOTE: When using a pair of channels in 'bridged' mode (see Bridge below), input signal must be connected to the odd numbered channel. Level: These screw-driver adjustable controls determine the level of input signals allowed into the channels. Level provides a gain range from 'off' (min. ) to 'unity' (max. ). The Level control is factory set for -24dB of gain, which will produce maximum output power with input signal peaks of +24dBu. For best performance, first adjust the source signals for optimum (maximum) levels, then adjust the MCA Series Level controls for the desired volume. When a pair of channels are bridged, their wattage is combined, but the minimum load increases to 8 ohms (MCA 8050 = 100 watts @ 8 ohms; MCA 8150 = 300 watts @ 8 ohms). 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 related switch to the down position. Connect the source signal to the odd numbered input channel, connect the positive speaker line to the (+) output terminal of the odd numbered channel, and connect the negative speaker line to the (+) output terminal of the even numbered channel (see diagram on right). NOTE: Only adjacent odd/even numbered channels, which share a common Bridge switch, can be bridged. The negative (-) output terminals on bridged channels are not used (no connection). For remote control of a bridged pair of channels, only the odd numbered input channel requires control (see Remote Control below). source signal signal / peak signal / peak 2 level OFF OFF OFF 1 level input HPF BRIDGE HPF input 2 outputs 1 speaker negative speaker positive REMOTE CONTROL The 15-pin Sub-D (female) Remote Control connector provides terminals for remote level/mute control of Channels 1~8 (see diagram & table on right). A variable control voltage (0~+10 VDC) is used to control levels (+10 VDC = unity gain; 0 VDC = off). Remote Control provides +10V and ground terminals (for use with potentiometers), but external `ramp' voltage devices may be used instead. Potentiometers should be 25k linear taper, and are wired with high to +10V, low to ground, and wiper to the desired channel terminal(s). The wiper of a single potentiometer may be wired to multiple control terminals (to control a group of channels).
