Switch Positions
ID 1 through 8 Function

Each of the predefined functions has two IDs (1) and (2) to allow two remote controls
to perform the same function.
*Switch Positions: 1 = ON; 0 = OFF

*Switch Positions: 1 = ON; 0 = OFF

The DX-RVC is a real-time remote volume
control for use with the DX8 and DX810 Digital
Audio Mixer/Signal Processor. The DX-RVC can be
programmed to operate the volume for any of the
eight inputs, any output, or grouped outputs. The
predened functions are programmed via the eight
DIP-switches on the back of the circuit board. Up
to nine remote controls (including the DX-RVC
and the DX-SW4) can be connected to the DX8 or
DX810 REMOTE BUS connector.

Quick-Start Guide

SAFETY FIRST!

Before connecting and using the equipment,
please read this Quick-Start Guide carefully
and keep it for future reference.

WARNING! This equipment has been
designed to be installed by qualied
professionals only! There are many factors to
be considered when installing professional
sound reinforcement systems. Some of these
factors include mechanical and electrical
considerations, as well as acoustic coverage
and performance. LOUD Technologies strongly
recommends that this equipment be installed
only by a professional sound installer or
contractor.

1. Never install, connect, or disconnect the
remote control with the DX8 or DX810
power supply on.

2. Before applying power to the DX-RVC, make
sure the wiring is correct as described in
this Quick-Start Guide.

CAUTION: To avoid the risk of electric

shock, never allow this equipment to be

exposed to rain or dampness.

FRONT PANEL FEATURES

UP/DOWN VOLUME CONTROL

Use to adjust the level for the Input, Output, or Group

assigned to the remote control. Duplicates the func­tion of the UP/DOWN buttons on the DX8/DX810
front panel.

LED DISPLAY

Indicates the level setting of the Input, Output,

or Group assigned to the remote control. "0" cor­responds to "10" on the DX8/DX810 front panel
LED display, which is unity gain. "+10" corresponds
to "OL" on the front panel LED display, which is
maximum gain.

REAR PANEL FEATURES

PREDEFINED FUNCTION SELECTION SWITCH

This 8-position DIP switch provides 256 unique func-

tions that can be assigned to the DX-RVC remote.
Refer to the chart on the back page for a list of all
predened functions currently available.

Each remote control must have the selection switch
set to a unique ID. When the DX8/DX810 is rst
turned on, it polls the REMOTE BUS and identies the
remote controls connected to it by each unique ID.

Many of the predened functions have two ID ad­dresses assigned to it to allow two remote controls
to be connected to a DX8 that both control the
same function.

CONNECTOR (J2)

Connect the wires from the DX8/DX810 REMOTE

BUS directly to this connector. Strip the wire back
about 1/4", insert the wire as far as it will go into
the connector and tighten down the screw with a
small slot-head screwdriver.

Use a high-quality three-conductor shielded cable

to make this connection, such as Belden 8451,
9451, or equivalent.

The connector is wired as follows:

INSTALLING THE DX-RVC

The DX-RVC can be installed in a single
standard electrical box, or in a double-gang box
along with a second DX-RVC or DX-SW4 remote
control.

CONNECTING MULTIPLE
REMOTE CONTROLS

Up to nine remote controls can
be connected to the DX8/DX810
REMOTE BUS. The maximum
length of the cable depends on the
type of cable used and the number
and type of remote controls used
in the system.

As a general rule, using 22
gauge wire (at 0.014 Ω/ft. and
34 pF/ft.), one remote can be up
to 3000 feet away, five remotes

can be up to 2500 feet away, and eight remotes
can be up to 500 feet away before transmission
losses become a factor.

DX8/DX810 DX-RVC

USING AN EXTERNAL POWER
SUPPLY

The DX-RVC is powered by the DX8/DX810
over the data lines. An external power supply
can be used by removing jumpers J3 and J5
from the DX-RVC circuit board, and connecting
a power supply rated at 9 to 16V AC or DC
to the PWR terminal on the connector (J2). A
number of "wall-warts" or bell transformers are
readily available from local electrical supply
houses with output ratings between 9V and
16V. Allow 25mA per remote.
