in bank 1 positions 1 through 6).
The 590-00 can learn up to 16 different commands on each of its
four banks. If more than 10 different IR commands are to be stored
use bank 2, 3, and 4 to store the sequence commands and bank one
positions 1-6 to execute the sequences.
1. Write down the order for each of the sequences required for all
of the six functions (not programmed with single commands).
2. Turn the bank 2 dip switch on; bank 1, 3, and 4 off.
3. Push PGM (program lamp goes on).
4. Using the wire attached to the 590-00 +12VDC, touch and
hold the other end of the wire to the 590-00 upper + row
terminal 1. While holding the wire in place, press the remote
control button of the first function while the remote is about
2-4" from the 590-00 internal infrared sensor. The 590-00
PROGRAM lamp will flicker while storing the IR signal.
When the IR signal is stored, the confirm lamp comes on.
Release the remote control button and release the wire to the
upper row terminal. The IR signal is now stored in the 590-00
bank 2 terminal 1.
5. Hold the end of the wire to the 590-00 upper + row terminal
2. While holding the wire in place, press the remote control
button of the second function while it is about 2-4 inches from
the 590-00 internal infrared sensor. The 590-00 PROGRAM
lamp will flicker while storing the information. When the
information is stored, the confirm lamp will come on. Release
the remote control button and release the wire to the upper
row terminal. The IR signal is now stored in the 590-00 bank 2
terminal 2.
In certain commercial applications a microphone paging override
is required. Model MR171 paging and override module takes a
balanced or unbalanced mic, (with defeatable phantom power) or
a line level input and when activated overrides all inputs (even if
some or all zones are in standby) and pages at a preset volume in
all zones.
A variety of door chime and telephone paging, door entry and
front door camera modules are being developed. Check our web
site for more information.

An innovative IR connection system is also included to turn on and

purpose. The Xantech 590-00 is a an IR sequence generator. When

6. Continue this procedure until all of the required sequence
commands have been learned by the 590-00. If more than 16
IR signals have to be learned, fill up bank 2 with the first 16
IR signals, then turn the bank 2 dip switch off, and the bank 3
switch on. Continue with bank 3 position 1, 2 etc. Use bank 4
positions 1, 2, etc., if required and bank 1 positions 7-16.

Installation
gather all the source remotes (with batteries inserted) near the 590-
00. Screw one end of a temporary wire to the 590-00 terminal
marked +12VDC. Power up the 590-00 and the MVP44a.
It is very important to use a top quality RJ45 8/8 crimper
tool. We strongly suggest using a cat 5 / RJ45 electronic
tester to verify the wire conductors.
The 590-00 can learn up to 16 different commands on each of its

use bank 2, 3, and 4 to store the sequence commands and bank one

quieter in standby modes.
6. ConnecttheMVP44aspeakeroutputstospeakersusinggood
quality speaker wire. Minimum 16 gauge copper wire is
recommended with 14 gauge minimum for runs over 30' (10m)
Make sure the speakers in each room are connected in phase.
Single IR Command Storing
Start by pushing the RES (reset) button on the back of the
590-00. If any of the six relay activations have a single command
(not a sequence of commands), program the single command(s) first.
For example if the jazz station tuner is on source C and you want to
program the IR command "scan" (two or more news stations have
been programmed in the news station tuner) into function C, program
the 590-00 with this first.
1. Make sure the bank 1 dip switch is on; bank 2, 3, and 4 off.
2. Push PGM (program lamp goes on).
3. Using the wire attached to the 590-00 +12VDC, touch and
hold the other end of the wire to the 590-00 upper + row
terminal 2. While holding the wire in place, push the tuner
remote control button "scan" while it is about 2-4 inches from
the 590-00 internal infrared sensor. The 590-00 PROGRAM
lamp will flicker while storing the IR signal. When the IR signal
is stored, the confirm lamp comes on. Release the remote
control button and release the wire to the upper row terminal.
The IR signal is now stored in the 590-00 bank 1 terminal 2.
4. Store any other single commands in bank 1 positions 1 and 3-6.
5. Push PGM (program lamp will go out).

7. Install MR60 keypads (or infrared receivers) in the rooms with
the speakers. Cat 3 or cat 5 wire can be home run to the MVP44a or
up to three rooms daisy chained on one wire.
***Be sure to set the dip switch on the rear of the MR60***
See the dip switch adjustment below. Connect all eight individual
wires using RJ45 connectors. Four wire conductors are needed for
each keypad (one unique, common: IR , ground and 12VDC).

the third MR60 to three. At the rear of the MVP44a, the RJ45

corresponding speaker outputs will be the same number as selected

Programming the 590-00
IR functions do not have to be related to the source input. For
example, if source A is a CD player and source B is a jazz tuner,
function A could be a sequence of CD skip, CD play, and CD
random. Function B could be CD Skip to next disk. After deciding
and writing down the commands to be programmed for each of the
six pulse activations (Function A, B, C, D, TON and TOFF),
After installation, if the keypads are not working properly or not
controlling at all, Check the MR60 dip switch settings, wiring
layout and crimp as well as bank connections very carefully.
