Input
These plug-in barrier strips provide the balanced line-level inputs to the channels. For balanced
connection, wire high (+), low (-), and ground ( ). 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.
Signal / Peak Indicators
These 2-color LEDs indicate the signal level for each channel. When an LED is green, that channel
has signal (above -30dB). When an LED is red, that channel signal is clipping (max. power).
CAUTION: Signal levels should be adjusted to avoid clipping. 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. 5).
