SS 4.2 Installation and Operation Manual
DESCRIPTION
Controls:
• Headphone monitor switch to select which output channel is monitored.
• Headphone jack
• Headphone level control
Audio Inputs:
Each of the 4 stereo inputs are balanced bridging (20KW) at a nominal line level of
+4dBu. Sufficient gain is provided for unbalanced consumer level products. Multi-
turn level controls are provided for each channel.
Audio Outputs:
The SS 4.2 provides two balanced stereo outputs. Two balanced monaural outputs
are also provided which follow their respective stereo outputs. The outputs may be
adjusted.
Silence Sensor:
The SS 4.2 contains individual silence sensors for each of stereo output channels.
For each channel, a detector monitors the sum of each stereo channel. The factory
default delay is set at 10 seconds, with a threshold of -30 dB, while the restore time
is set at 10 seconds. Upon silence delay detection, the “SS-1 or SS-2” spst relay is
closed for the duration of the silence and the Corresponding (SS-1 or SS-2) LED is
lit for duration of silence. The sensor may be programmed for:
• Number of seconds of silence that must be present before an alarm state is
reached or terminated.
• Number of seconds that valid audio must be present before an alarm state is
cleared.
• Remote Control (GPI) Inputs:
• Most front panel functions may be controlled with the 5-volt TTL/CMOS logic
compatible, contact closure inputs.
PIP (GPI) Input:
The Parallel Input Port with the Programmable Pulse Stretcher provides 16 pulse-
stretched parallel 5-volt TTL/CMOS compatible GPI inputs. The inputs are pulled
high to 5 volts through a 20KW resistor and are activated by pulling the input to
ground. These inputs supply status to any serial polling device (when the unit ID is
set to 0, no polling of inputs is required). For each channel, a pulse of specified min-
imum input duration (000 to 2.55 Seconds) causes the status to go true or the end of
the input pulse.
