Quick Start Guide

Getting Started
A typical setup is shown above. The most important piece of the setup is the VSA-51R. It would normally be located close to the Projector and typically placed in an
enclosure or vault. The entire s ys tem uses only one power supply which is connected
to the VSA-51-R (power supply is not shown in the above diagram).

Digital AV Room Control System
AV inpu ts
All AV inputs are truly plug and pl ay. T hey c onnect to the VSA-51-R via UTP cable.
The VSA-51 allows for up to 5 input sourc es: 2x VGA, 2x Composite, 1x HDMI/DVI.
The VGA and HDMI input plates require two UTP c abl es while the composite wallplates need only one.
Make sure that you connect the cabl es to the correct ports.
VSA-C-DP Front and Rear
1. Composite Video input.
2. Left and Right audio input on RCA connectors.
3. Power LED indicates power received f rom VSA-51-R.
4. RJ45 Port A connects to Port A of CV 1 or CV 2 on the VSA-51-R via Cat5 cable.
VSA-H-DP Front and Rear
1. HDMI input with threaded insert for c ompatible locking HDMI cables.
2. Left and Right audio input on RCA connectors.
3. Power LED indicates power received f rom VSA-51-R.
4. RJ45 Port A connects to Port A of HDMI/ DV I on the VSA-51-R via Cat5e/6
cable.
5. RJ45 Port B connects t o Port B of HDMI/DVI on the VSA-51-R via Cat5e/6
cable.

1. VGA input accepts both RGBHV and YPbPr si gnal s on an HD15 connector.
2. Local VGA Output loops the VGA input signal out for use at a local display.
3. Power LED indicates power received f rom VSA-51-R.
4. Audio Output loops the Audio input out for use at a local audi o monitor.
5. Audio input accepts stereo audio on a 3.5mm jack.
6. RJ45 Port A connects to Port A of V G A 1 or 2 on the VSA-51-R via Cat5 cable.
7. RJ45 Port B connects t o Port B of VGA1 or 2 on the VSA-51-R via Cat5 cable.

14. Speaker terminals for use with 8 or 16 Ohm speakers.
15. RS 232 Serial output. Connects to the prim ary display.
16. V i deo Outputs to dis pl ay via HDMI, composite video or VGA/YPbPr.
lower loads may cause over-current shutdown of the Audio amp, which
would require an All-Mute procedure to reset the amp. If you will be
using a single speaker connection for each side use 8 or 16 Ω speakers.
The amp can drive around 45 watts total into 8 Ω loads, which can be
very loud for a small room. Using 16 Ω speakers will cut the power
delivered by half.
To drive 2 speakers from each side, you need to connect two 16 Ω
speakers in parallel or two 8 Ω or 4Ω speakers in series as shown
below. Never connect two 8 Ω speakers in Parallel!
VSA -UI-DP User Interface Keypad
The VSA-UI-DP is the optional wall mount keypad used to control the system . Of
course the system can be controlled via the state-of-the-art web control using S mart
phones, tablets, or PCs , however, the UI gives the ability to control the system directly,
adds IR capabilities (extends I R as well as i ssuing programmed IR commands), and
adds a 2
nd
RS-232 port.

Double-Mute If there is no amplified audio output, the audio amp may be shut-
The UI buttons are configured as above when shipped, however 8 of the but tons are
user configurable. So if you don’t have all 5 inputs, you can assign the extra inputs
(and the 2 Auxiliary buttons) for other purposes, such as screen up/down control,
projector lift control , or serial or IR control of other equipment such as DVD players.
Recovering from Audio Amp Shutdown
In rare instances it is possible for the audio amp in the Receiver to shut down due to
an instantaneous over current condition. The amp requires 8 Ω or higher load on each
side. If the load has lower resis tance and if you have a large impulse on the audio
input that exceeds several volts, t he audi o amp will shut-down to protect against
damage. You can recover from this condition using a “Double Mute” procedure
whereby both the mic and the AV sourc e volume are muted at the same tim e. This will
reset the audio amp and bring it out of shutdown.
down due to over current. To recover from this condition, mute the
microphone and the A/V source simultaneously. This will reset the
amp. Upon un-muting either source, the Amp should be working
Accessories
Several accessories are availabl e with t he V SA-51 system. These include:
VSA-MNT
The VSA-MNT is a ceiling projec t or drop mount with locking
cage. The projector mount i s universally compatible with most
7
projectors. The VSA-51-R mounts inside the cage keeping connections securely
fastened and all electronic s below the ceiling. The projector inversely mounts to the
bottom of the cage and c an be adj us ted on 3-axis using the adjustment knobs.
VSA-UI-8
The VSA-UI-8 expands the UI panel capabilit y by adding 8 addi t i onal
buttons. Each button i s programmable via the Web Manager software. The
VSA-UI-8 connects directly to the VSA-UI-DP via a short cable.
VSA-PGSNS
The VSA-PGSNS is an opti onal kit to enable the Priority Page
Sense Mute feature. It uses a non-invasive sensor that monitors
existing PA lines without having to splice into the wires. The
sensor detects when the PA s ys t em is activated and sends a
signal to the VSA-51 to mute the audio. Once the PA line goes
quiet the VSA-51 resumes audio.

W eb Configuration & real time IP Control
The VSA-51 offers true flexibili ty in access and control embedded in the rec ei ver and
served over HTTP to a browser. This means you can access and control the device
from a PC, Mac, smart phone, or tablet without having to install any sof t ware or App
VSA IP Manager
The Web Manager is divided int o 3 main top level sections: Status , Control and
Configuration. The Status t ab di splays a summary of unique informat i on about the
system configurat i on and i t s state.
The Control tab displays a dynami c user interface to control the system , similar to the
User Interface panel (VSA-UI-DP) and expansion (VSA-UI-8).
The Configuration tab is where all configuration takes place including system settings,
users, actions, but tons, grouping, and scheduling.
