686-10

REMOTE SPEAKER SWITCHER

The 686-10 is an infrared remote controlled Speaker Switcher. It allows the user to turn six stereo pairs of
speakers ON and OFF by way of IR commands from a Xantech RC68+ (or RC68) Programmer. The RC68+
commands are "taught" to learning devices and passed to the 686-10 signal input terminals via Xantech IR
receivers and keypads. Individual speaker pairs may be turned on or off in any particular room or all
speakers turned on and off from any room for a "party mode".

use of multiple 686-10's. The 686-10's Code Group number is 98.

• Universal mounting fits 19-inch racks or any 3-1/2" X 19" surface. Projects about 2-3/4 inches behind
panel with cables connected.

• Power: 12 VDC @ 300mA.

• Dimensions: 19" W x 3-1/2" H x 2-1/4" D.

RC68 PROGRAMMER / REMOTE CONTROL

The RC68+ Programmer (available separately) contains all commands necessary to operate the 686-10
(see Fig. 2).

• You will need it to program universal learning devices such as the Xantech URC-1 learning remote, the
Xantech Smart Pads, the 590 Controller, the 710 Fone Link, etc., with commands that operate the 686-

10.

• NOTE: The RC68+ codes operate several other Xantech models as well, such as the RS41AV, CC12,
ZPR68, etc. Therefore, only the button descriptions that apply to the operation of the 686-10 are
listed. All others should be ignored.

CAUTION: While the RC68+ can be used as a handheld remote control, it is highly recommended it not
be given to the final user for the following reasons:

• Since it includes adjustable code groups, the user may inadvertently alter the installed 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 686-10, all commands should be consolidated into one learning device, for ease
of use.

Speaker Relay Command Modes.

Depending on the installation, you may want to have the 686-10 respond to IR commands in different ways.
The basic modes of operation for each speaker relay on the 686-10 are as follows:

OFF -Turns the selected speaker relay OFF.
ON - Turns the selected speaker relay ON.

These dedicated OFF and ON (paired) commands are helpful when sending IR commands "blind" from

secondary rooms when you have no visual aid for status.

TGL - (Toggle Mode) - Switches the selected speaker relay ON when the TGL command is sent and OFF

when it is sent again. If the relay is ON, it will turn OFF-- if it is OFF it will turn ON when the code is
sent.

MMT- (Momentary Mode) - Turns the selected speaker relay ON when the code is sent. The ON condition

only

remains

as long as the MMT code is being sent. The relay is normally OFF.

GP-ON (Group ON) - This button (labeled F8 on the button face) causes the 686-10 to turn all speaker relays

ON at the same time. GP-ON overrides all individual settings.

GP-OFF (Group OFF) - This button (labeled D8 on the button face) causes the 686-10 to turn all 6 speaker

relays OFF (or any selected single relay).
NOTE: OFF, ON and TGL (toggle) operation will still operate for any individual speaker relay after

Group ON is executed.

Power Interruption Status

The 686-10 should normally be plugged into an unswitched AC outlet. However, if the power to the 686­10 is interrupted by a power failure or other reason, the internal memory will retain the last selected
switched status for each of the speaker relays.

INSTALLATION

Fig. 3 shows a typical application of a 686-10 in a multiroom system. The amplifier and speakers are
connected to the Model 686-10 by the four-terminal plug-in connectors.

The order of the stereo speaker pairs used is not important. If you have only two pair of speakers connected
to positions 5 and 6, they will work just as well as they would connected to positions 1 and 2.

The PROTECTION RESISTOR switch connects a four-Ohm resistor IN and OUT of a series connection with
the amplifier. The purpose of the resistor is to prevent loading the amplifier with less than four Ohms with
any combination of speakers. Since the 686-10 connects speakers in parallel, anytime two or more pair
of speakers are active the impedance would be less than four Ohms (a typical "eight-Ohm" speaker usually
has an actual impedance of less than eight Ohms somewhere between 20 Hz and 20 kHz). When all six
pair of eight-ohm speakers are active and the protection resistor is switched OUT, the parallel impedance
is less than 1-1/3 Ohms. With the resistor switched IN, the impedance will be less than 5-1/3 Ohms but
always more than four Ohms.

NOTE: When the 686-10 is connected to Xantech 760-00 Match Maker room volume controls, as shown
in Fig. 3, the PROTECTION RESISTOR is not necessary, since the Match Makers, when set correctly, will
provide the proper impedance match to the multiple speakers with virtually no power loss. In this case, be
sure the PROTECTION RESISTOR switch is set to the "OUT" position to prevent the waste of amplifier
power.

• • •

IMPORTANT

• • •

1. The Model 686-10 is intended to be mounted on a vertical surface so that the ventilation slots are at

the top and the bottom of the unit. Air should be allowed to circulate into the bottom slots and out of
the top slots, particularly when the PROTECTION RESISTOR is switched IN. The Model 686-10 will
mount onto a standard 19-inch rack.

2. Power Supply Considerations. Because of the high current requirement of the relays in the Model 686-

must

10, the Xantech Model 782 High Current Regulated Power Supply

be used. In Fig. 3, all of the

system IR control devices are also powered from the 782 through the 686-10.
To be sure you have sufficient power supply capability in your particular system, calculate the total

current required by using the method shown in the 791-44 instructions, then add 300 mA for the
686-10. If the total exceeds 1A, use a second supply to power the IR devices separately through the
791-44.

When the installation requires more than six sets of speaker pairs, two or more 686-10's may be connected
as shown in Fig. 4.

When using multiple 686-10's, keep the following items in mind:

1. Follow the instructions that come with the 760-00 Match Maker volume controls to ensure proper

impedance matching of all the speakers to the power amplifier.

2. Fig. 4 drives 18 stereo pairs, reflecting an impedance of 3.56 Ohms to the power amplifier (assuming

all speakers are 8 Ohms each and the 760's are all set to the 8X position). This is satisfactory provided
the amplifier you are using is safe into 3.56 Ohms. If not, you may need to switch the PROTECTION
RESISTOR to the IN position on one or more of the 686-10's, or use additional amplifier(s) to drive the
686-10's individually.

3. Remember, when you switch a PROTECTION RESISTOR IN, the volume level to the speakers will

be decreased.

4. When using multiple 686-10's or in combination with a 680-10 or other devices that respond to RC68+

codes, be sure each is set to a different IR CODE GROUP. Refer to Fig. 2 and the RC68+ Programmer
Instructions.

5. To perform Group ON and OFF with multiple 686-10's, it is necessary to sequence (macro) the different

ON and OFF codes for each 686-10 in a learning device, such as the Xantech URC-1 Remote, a Smart
Pad™, or a 590-00 Controller.

6. A CB18 Strip-IR Connecting Block is used in Fig. 4 to make the parallel connections from the IR

devices to the 791-44 Connecting Block. In this example, only 8 IR devices are shown connected to
the CB18. You would actually have to "double-up" on each of these connections if you need IR control
from all 18 rooms, or use an additional CB18.
