THE 3203 TIMER CONTROLLER FROM REVOX

Description

The 8203 is an Interactive Switcher-Timer-PC Interface
controller. Specifically designed to be Integrated in the current
REVOX line, the 8203 is powered via the 8285 receiver serial port
and can be linked via patch cords (max. 8 inputs) to the "brain"
of the 8215, 8225, PR99, 8291 as well as to the less recent units
equipped with serial link retrofits.

The connection of 3 8206 transceivers for multiroom operation as
well as a RS-232 port are available for more sophisticated remote
or computer controlled operations.

Physically the 8203 can best be integrated in the 200 serie when
sitting on top of the 8225. The association of the two is matching
the height of the 8215 or B285 and may therefore be inStalled in a
conventional REVOX disco-rack U-board.

0n the front panel of the 8203 a function display and the I.R.
sensor are visible. 0n the back a row of sockets are available for
connection to the other units of the system. From right to left: 1
parallel remote control. 8 device outlets. 3 8206

extensions (ABC). 1 RS 232 port and an on/off battery buffer
switch. ,

The switcher (easy/select)

After selecting the easy mode. the "eosyness" of the operation of
the REVOX system becomes obvious, for example: Just pressing the
play next button on the 8205 remote control will trigger a serie
of Operations: In a split of a second the CD player is switched
on. starts to play the first cut. the receiver is also switched
on. the input "disc is selected and soon the music comes

out through the preselected speaker output (i.e. speaker A) with
the correct preselected power-on volume! Another example?

Pressing tape 1" on the receiver will switch on the B285 as well
as start the 8215 in play mode, or from another room, via the
8206. pressing play will activate the 8215 in play mode and the
music will be heard through the preselected speaker.

in practice. the easy configuration is entered only once the
first time used (it can of course be altered anytime). The menu:
Time. date, language, easy on/off. timer on/off and speaker
selection. When completed the user can sit back, relax and enjoy
music literally at the touch of a button.

The 8203 timer prograaming operations are very much like those
practiced in video recorders. One can select and program up to

5 events. Each event occurs at a given starting time, date

(or dayis) of the week). Then, after selecting among sources such
as tunerl CD. tape, phono. one can direct the signal to a
recorder, amplifier or speaker. The program will be interrupted
at a stop-time, to mark the end of the event.

3 back-up batteries secure the program in case of power failure.
An exit button can be used to escape and reset 0 progranming

in progress and another button is available to the user to test
a progranned event independently from the schedule and with no
harm to the Dre-established sequence.

This quite sophisticated timer, as one can see. will become handy
for early-bed-goers"-audiophiles!

The PC interface (RS-232 interface)

All 8203 internal functions (easy" and timer) can be
individually activated with control feedback.

The connection to a maximum of 8 units can be realised via bibus"
cables and each unit can be individually activated with control
feedback (if implemented).

A unit equipped with a parallel socket (9-pol) can be individually
activated as well (no control feedback).
