Signal Wiring Guidelines
Control Endplate
Input Connection:
Connect the right and left input signals to the corresponding
RCA input jacks on the end of the Studio 100. Keep these
wires close to each other and far away from power and
speaker wires. When using in bridged mono mode, put the
input mode switch in the "MONO" position.
Input Sensitivity:
The input sensitivity or "gain" is user adjustable and can be set
anywhere between .230 volts (230 millivolts) and 2.3 volts. If
you are unsure of your head unit's maximum undistorted output
level, set these controls to their minimum (quietest) position
and then turn the head unit's volume knob up until you can
start to hear audible distortion and reduce the volume until the
distortion goes away. At this volume setting, gradually
increase the amplifier's sensitivity until you can start to hear
distortion from the amplifier. Then reduce the sensitivity until it
goes away. Using this method, the head unit's volume should
reach approximately 3/4 of its maximum or more before
distortion is heard in the system.
Speaker Connections:
Connect the speaker wiring to the terminals as they are
labeled. The minimum impedance or "ohm load" for each
individual channel is two ohms. When bridging the front and
rear channel into a mono configuration, the minimum
impedance is four ohms.
