Figure 8 : LUWMT1A Connection to RCA Jack on Amplifier RCA Jack LUWMT1A Amplifier LUWMT1A Connector An RCA jack is provided near the output terminal strip for connection to an LUWMT1A impedance matching transformer (Com Code 405891680). A 600-ohm, telephone level output signal can be obtained by plugging the RCA connector of the LUWMT1A into this jack and taking the output signal off of the LUWMT1A screw terminals (see Figure 8). -
Page 11: Operation
Operation IMPORTANT: Before plugging the amplifier into an AC outlet, turn all volume controls to their full counterclockwise positions and all other controls to their reference position or to mid rotation. Indicators POWER IND The POWER IND LED illuminates whenever AC power is applied to the amplifier (there is no power switch on the amplifier). - Page 12 MUSIC VOLUME This control adjusts the level of the background music output. No reference level setting position is provided. The background music level should be set to an acceptable level without overdriving the system. When adjusting this level, the PEAK LEVEL indicator should be observed to ensure that the amplifier signal is not distorted.
