(1) Inputs 1~4: Each input is provided on both BNC and RCA type connectors, which are wired in parallel. Inputs 1~4 will accept any
video signals from cameras, VCRs, laser-discs, cable, satellite, etc. The VSX41 may instead be used as an audio switcher, with Inputs
1~4 accepting any mono line level audio signals from mixers, tapes, CDs, VCRs, cable, satellite, etc. Connections for audio signals are
typically unbalanced, wired with (+) to tip and (ground) to sleeve. However, if all audio signals to be connected are balanced, they may be
wired with (+) to tip and (-) to sleeve (the input/output grounds are connected directly, bypassing the VSX41). The VSX41 may also be
used as a 1-in/4-out video (or audio) "router", with a single input being switched to one of four outputs (see Applications on page 9). From
the factory, Inputs 1~4 have 'back-termination' of 3.9k ohms, which is appropriate for most applications. However, internal jumpers allow
selection of 75 ohm 'back-termination', which is required only for specific video applications (see Options on page 6).
(2) Output: The Output is provided on both BNC and RCA type connectors, which are wired in parallel. The VSX41 is a passive
switching device (using dry contact relays), and will provide an output signal identical to the selected input signal. The VSX41 does not
provide any processing, synchronization, or amplification of signals. The VSX41 may instead be used as an audio switcher, with Inputs
1~4 accepting (and the Output providing) mono line level audio signals. Connections for audio signals are typically unbalanced, wired with
(+) to tip and (ground) to sleeve. However, if all audio signals to be connected are balanced, they may be wired with (+) to tip and (-) to
sleeve (the input/output grounds are connected directly, bypassing the VSX41). The VSX41 may also be used as a 1-in/4-out video (or
audio) "router", with a single input being switched to one of four outputs. This is accomplished simply by connecting to the VSX41 Output
as if it were a single input. Inputs 1~4 are then utilized as the four possible outputs (see Applications on page 9).
(3) Remote 1 & Remote 2: These screw terminals are for connection of optional remote controls (see Remote Control on pages 4 & 5).
Including the Internal Infrared Receiver, the Remote Translator (4), and the Logic Inputs (6), these terminals allow remote control from up
to five locations. Optional remote controls may be wired up to 2000 feet from the VSX41, using 2-conductor shielded cable.

),
(4) Remote Translator: These screw terminals are for connection of certain third-party controllers (such as AMX
and CRESTRON
which generate "carrier-stripped" remote control signals. Two remote translator inputs are provided. The Low terminal being used for
controllers which produce a "low" output level (-15VDC ~ +2VDC) when idle. The High terminal is for controllers which produce a "high"
output level (+2VDC ~ +15VDC) when idle. The third-party controller must be programmed to output a bitstream in the Biamp format
(contact the controller manufacturer to determine if their device driver library currently supports the Biamp format).
®
(5) Remote Output: These screw terminals are for connection to other ADVANTAGE
products having similar remote control capabilities
(such as the SPM412e, SPM522D, DRC4+4, PMX84, and EQ282M). Remote Output combines the commands from VSX41 front panel
switches, remote controls, & logic inputs, for simultaneous remote control of additional devices (see Applications on page 7).
(6) Logic Inputs: This 9-pin Subminiature D (female) connector provides four logic inputs and their related ground. Logic Inputs allow
remote control of the VSX41 Channel Select switching function via external logic output circuits, contact closures, or active driver circuits
(see Remote Control on page 5). Remote control via logic output circuits is possible from other ADVANTAGE products, such as the AGII,
DRC4+4, and PMX84 (see Applications on page 8). Remote control via contact closures is possible using switches, relays, or certain third-
party controllers (see Applications on page 9). The Logic Inputs may also be remotely controlled via active driver circuits (such as a TTL or
RS-232 output). Logic Inputs also include a "priority switching" scheme and internal jumpers for input pin assignment.
(7) AC Power Cord: The external power transformer provides 27 Volts AC to the VSX41, and is detachable via a 5-pin DIN connector.
The VSX41 has two internal 1 Amp Normal-Blow (1A NB) fuses. If fuses should require replacement, use same fuse value and type only.
