Level controls
When using the level controls, first start with them turned all the way up (clockwise).
Then adjust them according to your system requirements to match the sound level
coming from each speaker. This is a rough adjustment for matching different driver
impedances. Any fine tuning should be done by the preamplifier
Example: When using 4 ohm and 8 ohm speakers together, the 4 ohm may sound louder
than the 8 ohm at a given volume level. The level controls on the amplifier are used to
match the speakers volume levels. Clockwise will increase the output. Counter
Clockwise will decrease the output.
Inputs
RCA type connectors accept line inputs from the preamplifier’s output connectors. There
are five/six input connectors, one for each channel, that may be used to connect the
amplifier to the preamplifier.
