EMM Labs SWITCHMAN-3 - Manual (Page 5)

-
none of the channels is mute (all Input Systems)
SwitchMan-3 uses a nonvolatile memory (NVRAM) to store Template files. A template
is a data file that saves system settings. The NVRAM contains six templates. In a
new system, all templates are initialized to default values, as listed above.
1.2 Operation
From a user standpoint, the SwitchMan-3 system operates in three fundamental
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
The system offers several functions in the Volume Control Mode:
- Master Volume Adjustment using the rotary knob at the center of the Remote
- Input Selection using buttons A, B, C, and D, on the left side of the Remote
- System Mute (all channels) using MUTE button
- channel setting inspection, using channel buttons 1, 2, 3, 4, 5, and 6 on the
right side of the Remote
- switching to the Channel Trim Mode using TRIM button
- Template Load or Template Save using LOAD/SAVE 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.
