INSTALLATION ......................................................................

Figure 1: Input option removal and assembly

Before installing an input option, be sure to disconnect the amplifier from

power. To remove the standard input panel, unscrew the four corner screws and

gently pull the assembly out. There will be two terminals already connected and one

remaining disconnected. The two 3-conductor shielded wires which terminate at the

six pin header are the audio signal paths to the amplifier. Slowly rock the connector

back and forth while exerting a constant pull and it will come right off. Note that there

is a friction lock tab and ramp on the header set, indicating proper polarity during

reassembly. The black wire terminated with a spade fast-on is the chassis ground.

This is connected to the PCB via a riveted fast-tab. If during reassembly this fast-on

feels loose, remove and squeeze the blue spade with pliers to assure good contact. The

last connector, the power supply, is shipped disconnected because the standard input

is passive. Depending on the amp model, these three wires will be either red, violet,

and black, or blue, blue, and yellow. The three pin power supply header set is

polarized for proper mating. Once these three connectors are plugged into the new

option, gently replace the panel and screws.

both. The input transformer provides complete electrical isolation between the

amplifier and its signal source to eliminate any ground-induced hum noise. The

transformer input also further reduces any common-mode noise and radio

frequency interference. The precision 1:1 transformer will not affect any controls

on the standard input. Input attenuation occurs prior to the primary windings,

allowing for high level input signals
