“Input Mode” Switch
The Control Panel houses an “Input Mode” switch located under the “General Setup” heading. This switch allows operation of all four amplifier channels with only one pair of input signals or with independent front and rear input signal pairs.
To use separate inputs for the “Front” and “Rear” amplifier sections, (in order to permit
To operate all four channels of the HD600/4 with a single pair of stereo inputs, select the “2 Ch.” position on the “Input Mode” switch and connect a single pair of input cables to the “Front” input jacks only. In this mode, the amplifier will route the signals connected to the “Front” inputs to the Front and Rear amplifier channels.
CHANNEL CONTROL SECTIONS
Flanking the “General Setup” section on the Control Panel of the amplifer are two sets of identical controls: one for the “Rear Channel Controls” (on the left side) and one for the “Front Channel Controls” of the amplifier (on the right side).
In each of these sections you will find an “Input Voltage” range switch and a rotary control labeled “Input Sens.” (Input Sensitivity). These controls are designed to match the input sensitivity of the HD600/4 to the specific signal source that is feeding it and must be adjusted, with care, following the procedures outlined in this manual. Failure to make correct adjustments can result in weak output, excessive distortion and/or undesirable noise in the audio output of the amplifier!
Note: The Channel Control sections also house “Filter Mode”, “Filter Slope” and “Filter Freq.” controls. These are crossover filter controls and will be discussed in the next section of this manual. This section will explain the Input Controls only.
