EMM Labs SWITCHMAN-3 - Manual (Page 4)

2. Getting Started
Caution Before turning this unit on, you MUST verify that the
system is set for the correct AC Mains voltage in your
area. The factory set voltage is indicated on the back of
the unit.
1.1 Quick Set-up
Main Unit has one port dedicated to the connection with the Remote. Look for
DB-9 modular connectors on the back panels of both units. The Remote is powered
from the Main Unit.
Typical set-up procedure will consist of the following steps:
-
connect the Remote to the Main Unit using the cable provided, secure the
connectors in place
-
connect audio systems to the Main Unit
-
power up SwitchMan Main Unit.
The Remote-to-Main cable is terminated with DB-9 plugs: male connector on the
Main Unit side and female connector on the Remote side. Please note that DB-9
terminated cables are commonly used to connect RS-232 peripheral devices to
personal computers. On a personal computer, those DB-9 connectors are marked as
COM ports. SwitchMan’s Remote Unit is NOT an RS-232 compatible device, thus
never connect SwitchMan Remotes to COM ports on personal computers,
never connect SwitchMan Main Units to COM ports on personal computers.
After first-time power-up, the Remote should present the following information:
-
Master Volume setting of 20 on the numerical display
-
input system indicator LED (green) should be lit at System A
-
all other LED indicators should be turned off.
The system A selector (green LED) on the Main Unit’s front panel should be lit as
well. At this point, the SwitchMan-3 is ready for operation. Turning the main knob at
the center of the Remote adjusts the Master Volume. The volume setting is displayed
as a step number ranging from 0 (“zero”, full attenuation) to 110 (max. volume).
The initial configuration of the system is as follows:
-
Input System A is selected
-
Master Volume level is step no. 20 (all Input Systems)
-
Channel Trim value is 0 (all channels, all Input Systems)
