Run CAT5 wire from the keypad location to the GSZ67 location for each keypad or run it from keypad to keypad location. Ideally home runs are used as they leave the installation more “future proof” and reliable. Leave an extra 1 m or 3 feet on each side to make it easier to work on. Add a RJ45 connector of the right type for the CAT5 wire you have selected (not all CAT5 wires are the same) and crimp the connector to the wire on each side. Plug the RJ45’s into the MR164 and correct GSZ67 ports.

Note: MR164 keypad installer programming, see MR164 programming near the end of this manual.

Infrared connections

On the rear of the GSZ67 there are seven infrared pass though ports. Each of the 1 through 6 corresponds to the keypad port next to them. For example IR port #3 is the infrared output for keypads connected to KEYPAD #3. The infrared ALL is the combination of all of the 6-keypad ports.

Using this method of infrared routing you can have six sources the same (like 6 identical AM/FM tuners) one for each zone and they can be controlled individually in each room. Each port can control up to 8 devices using 4 of our optional IR34a emitters and one IR55 connection block.

Each infrared port is a standard 3.5mm mono jack.

DATA IN and DATA OUT connections

On the rear of the GSZ67 amplifier there are two 3.5mm stereo jacks labeled DATA IN and DATA OUT. These ports connect two or more GSZ67’s together so they can share infrared commands and ALL commands (such as All Off)

When connecting two GSZ67’s together in one system you will need:

1.Up to fourteen (one for each active source) RCA patch cords

2.A 3.5mm stereo patch cord.

We do not recommend using “Y” adaptors in this case. Normally the two GSZ67’s are near each other. If they are far apart then balancing baluns may be required to eliminate stray noise on the lines.

The procedure to connect the two controller amplifiers is:

1.Connect the “Data Out” jack on GSZ67 #1 to the “Data In” jack on GSZ67

#2.using the 3.5mm stereo patch cord.
