RP41AV

REMOTE PREAMP

GENERAL INFORMATION

The RP41AV, Fig. 1, is a fully functional infrared remote controlled audio/video preamp. Volume, Bass,
Treble, Balance and Mute functions, in addition to A/V input switching, provide all the functions needed for
multi-room systems. It features a low noise, low distortion design with high headroom capability, for highest
audio and baseband video performance.

The RP41AV has the following features and functions:

• The model RC68+ (and RC68) handheld programmer (available separately), is the source of all the IR
(infrared) commands necessary to operate the RP41AV (see Fig. 2). Normally the installer would "teach"
these commands into a Xantech Learning Remote, Key Pad or other learning device for use by the
customer.

• Audio and video signals connected to four separate line level A/V inputs, labeled 1, 2, 3, and 4, may be
accessed in any order by IR commands.

• Separate Volume (Up/Down), Balance (Left/Right), Bass and Treble controls feature continuous
adjustment in 2 dB steps, in either direction, all IR controlled.

• Balance, Bass &Treble controls have a Flat function for instant return to flat response from any previous
setting.

• Separate Mute On & Mute Off functions ensure positive mute command execution without knowing
status. This is helpful in remote rooms when all adjustments are made “blind” without any visual aids for
status.

• IR control input port connects to the emitter output of Xantech devices, allowing remote control from
keypads, IR receivers, connecting blocks, etc.

• Tone controls allow individual "EQ" of each zone when using multiple RP41AV's in multi-zone installa­tions.

• The space saving “flat pack” design
allows great flexibility in mounting and
positioning.

PANEL DESCRIPTIONS

1. INPUT jacks. Connect to the corre-

sponding output jacks of source
components (satellite receiver, VCR,
camcorder, laser disc player, TV
surveillance camera, CD player, AM/
FM tuner, cassette tape deck, etc.).

2. OUTPUT jacks. Connect the

VIDEO output jack to the corresponding Video input jacks of AV receivers, TV monitors, VCRs, etc.
Connect the AUDIO LEFT and AUDIO RIGHT output jacks to the corresponding input jacks on a main

power amplifier. Since these are low-impedance outputs, you may connect up to 5 power amplifiers
to one RP41AV prodvided such amplifiers have input impedances of 22k Ohms or more. Use "Y"
connectors or other paralleling means.

4. G S terminals. Input terminals for the IR control signal. Connect a 2-conductor cable from the emitter

or signal output port of any Xantech Connecting Block, IR receiver, Key Pad, or Controller here. The
positive lead connects to "S" and the negative to "G".

5. IR CONFIRM LED. Lights when power is applied and flashes when IR commands are received.

RC68+ PROGRAMMER / REMOTE CONTROL

The RC68+ (and the RC68) programmer (available separately) contains all the commands necessary to
operate the RP41AV.

• You will need it to program universal learning devices such as the Xantech URC type learning remote,
the Xantech Smart Pads, the 590 Programmable Controller, the 710 Fone Link, etc., with commands that
operate the RP41AV.

• NOTE: The RC68+ will operate several other Xantech models as well, such as the RS41AV, ZPR68,
MIRV1, RAT1, etc. Therefore, only the button descriptions that apply to the operation of the RP41AV are
listed below. All others should be ignored.

• While the RC68+ will operate as a separate remote control, it is highly recommended it not be given to
the final user for the following reasons:

Since it permits code group changes , the user may inadvertently alter the installer configurations.

• Also, since the user will require IR commands from other brands of equipment to control the total system,
in addition to those of the RP41AV, all commands should be consolidated into one learning device, for
ease of use.

3. INPUT Select buttons. Press buttons 1 through 4 to individually

select up to 4 audio/video sources connected to the RP41AV.

5. VOLUME Up/Down buttons. When pressed, volume will in-

crease and decrease in 2 dB steps between 0 dB and -80 dB.
When buttons are held down, the volume level will change
continuously.

6. MUTE ON / OFF buttons. Separate On / Off buttons give

positive mute commands without knowing what the status is.
This is very helpful in a remote room when all adjustments are
made “blind” without any visual aids for status.

NOTE: Mute is released (turned off) when a VOLUME, INPUT,
BALANCE, BASS or TREBLE button is pressed, in addition to
MUTE OFF.

9. BALANCE buttons. When the BALANCE "arrow" buttons are

pressed, the audio output will move to the left or right in 2 dB
steps with each left or right press. (No change will occur if they

are held down continuously).

10. Balance "Center" button. This button, when pressed (identified by "C_BAL"), will instantly return
the balance to the center position from any previous setting.

14. TREBLE & BASS control buttons. When the "arrow" buttons are pressed, the treble and bass
response can be increased or decreased from 0 dB to ± 12 dB in 2 dB steps with each up or down press.
(No change will occur if they are held down continuously). In "multi-zone" systems, you can use these
controls to "EQ" (equalize) the sound for each room's acoustic differences.
