1.2 Operation

From a user standpoint, the SwitchMan “Quartet” system operates in one of the
three modes:

-

Volume Control Mode

-

Channel Trim Mode

-

Template Load/Save Mode.

After power-up, the system always switches to the Volume Control Mode. This is the
fundamental operational mode.
SwitchMan Quartet is operated from a Remote Unit. The top panel of the Remote has
14 buttons, 1 rotary knob, 14 LED indicators, and a numerical display. In addition,
there are two buttons on the back: SHIFT (black) and Remote RESET (red.)

1.2.1 Volume Control Mode

- Master Volume adjustment using the rotary knob at the center of the Remote

- Input Selection using buttons

The volume setting is displayed as a step number ranging from

0

(“zero”, full

attenuation) to

110

(max. volume.)

Fast-blinking MUTE LED indicator (red) confirms that Mute function is engaged i.e.
all channels are at full attenuation. The main knob remains active, however, and the
display is being updated. Upon disengaging the Mute, the system returns to volume
setting as shown on the display.

Green LED indicator confirms Input System selection.
Yellow LED indicator confirms the Channel selection. The Channel Settings are
presented as follows:

- Level Trim value is shown on the numerical display
- channel mute status is indicated by red MUTE LED.

Channel Level Trim is displayed as a step number ranging from

–40

to

+40

. Trim step

equates to

0.25

dB. Trim settings are always displayed with a plus or minus sign;

the trim value of zero is displayed with a plus.
In Volume Control Mode no changes can be made to channel settings - when a
channel button is pressed, the settings are viewed only. If no other buttons are
pressed at this time, the system will wait 4 seconds, then restore the main display
(Master Volume step shown again) and turn off the channel LED indicator.

To modify a channel setting, please switch to the Trim Mode first.
