Introduction:

Thank you for your purchase of a Knoll GSZ67 12 channel controller amplifier and congratulations on your choice. The GSZ67 features six deluxe digital volume controlled stereo amplifiers with individual seven source selection. This is Knoll's third generation of multi-channel, high-quality power amplifiers. The GSZ67 is designed to meet the amplifier needs of custom installed multi-zone systems where high quality sound is a specific requirement.

Each of the six zones or rooms can select any of the seven inputs, with individual volume control, bass, treble and balance. Extras such as an external voltage trigger that can turn source equipment on and off, individual zone infrared outputs, a fully balanced paging override, RS232 control, fully buffered line level outputs and many more features give the GSZ67 exceptional value when installed in homes and large complex systems. Except for the power button all controls are rear mounted. A data port is provided for ganging multiple GSZ67's. Infrared signals can be relayed from the keypads to the source equipment.

The GSZ67 is normally controlled by MR164 LCD keypads with or without

Knoll remote controls or RS232 commands from whole house controllers. The paging override is normally used for whole house announcements or doorbell chimes.

Seven input source selection. Each of the six stereo amplifiers is provided with seven input source selection. Selection, volume level, bass, treble and balance is made on MR164 keypads, Knoll remote control (or a programmed remote control) or via an external controller. Rooms can have different source selections, volumes, etc.

Six internal 80 position stereo volume controls. The six zones can each require a MR164 keypad, RB12 remote control or external controller via

RS232. The keypads are typically mounted in the room with the speakers and they control amplifier power on/off, volume up/down and mute as well as source selection.

Cost and size efficiency. The GSZ67 consists of a total of 12 power amplifiers in one 3-1/2" high enclosure (two rack spaces). Each power amplifier channel can deliver 50 watts RMS with peaks of 100 watts. Because of its unique design the GSZ67 delivers exceptional value.

Automatic protection circuitry. Each GSZ67 amplifier channel is individually and fully protected against low impedance, overheating, overloading, over voltage and under voltage. The protection circuitry automatically restores the amplifier channel as soon as its parameter returns to the safe operating area.

5

Individual bass, treble and balance adjustment. Each channel features adjustments so installers can preset the room for speaker differences and listener preferences.

External trigger. The GSZ67 can turn on and off source components with its 12vdc trigger output.

All zone control. The MR164 keypad features all zone control of all off, all zones to any one source (then set volume at 1/3) and all zones volume up or down.

GSZ67 includes a quiet thermostat controlled internal fan to increase its long-term power output capability.

Infrared controller ports. Each zone or room has its own infrared output jack. An all zone jack is also provided.

Zones 5 and 6 have controlled line level outputs so larger power amplifiers can be connected to these outputs.

Optional rack mount version. Occupies two rack spaces.

Unpacking:

The carton and packing materials used in shipping your new amplifier were specially designed to protect it from the shock and vibration of shipping. We suggest that you save the carton and packing materials to use if you move, or if the unit ever needs to be shipped back to us for any reason. Should you discover that your amplifier has been damaged during shipping, please contact your dealer or

Knoll immediately and request the name of the carrier so a written claim can be made.

The right to a claim against a public carrier can be forfeited if the

carrier is not notified immediately in writing and if the shipping

carton and packing materials are not available for inspection by the

carrier. Save all packing materials until the claim is settled.

GSZ67 placement

During normal home operation the amplifier will become warm. However, there are instances during high-level playback into low impedance speakers when the amplifier will become much warmer than normal. To ensure the amplifier’s trouble-free operation, it is necessary to provide adequate ventilation. Your amplifier should be kept away from external sources of heat such as radiators and hot-air ducts. The amplifier should never be placed with other heat-producing components in a cabinet or enclosure lacking free airflow. Do not stack other components on top of your amplifier.

Connecting your amplifier

When making connections between any source components and the amplifier, or when making connections to any speaker, be certain that both the input devices and the amplifier are turned off. Unplug all equipment before making any connections so that there will be no unwanted signal transients that can damage equipment or speakers.

6

Input connections

Connecting the GSZ67 to your source equipment is straightforward. Using the highquality RCA audio interconnect cables, match the output channel designations on the rear of your source equipment to the input jacks on the rear panel of your amplifier that have the same channel name. When making connections with RCA type plugs on interconnect cables, make certain to gently, but firmly, insert the plug into the jack.

Loose connections can cause intermittent sound and may damage your speakers.

Some quality RCA plugs may be very tight, and it is important to secure a proper connection between the interconnection cable and the input jack.

Speaker connections

The GSZ67 has six stereo 50 watts per channel amplified outputs. Channels 5 and 6 also have line level outputs to connect to larger powered amplifiers.

To ensure that the high quality signals produced by your amplifier are carried to your speakers without loss of clarity or resolution, Knoll advises that you use high-quality speaker wire. Many brands of wire are available — the choice may be influenced by the distance between your speakers and the amplifier, the type of speakers you use, personal preferences, along with other factors.

Regardless of the brand or type of speaker wire chosen, we suggest that you use a wire constructed of fine, multi-strand copper with a gauge of 16 or less (the lower the number, the thicker the cable). Wire with a gauge of 16 may be used for short runs of less than 12 feet. We do not recommend that you use any wires with an AWG equivalent of 18 or higher due to the power loss and degradation in performance.

To connect the amplifiers to your speakers, a removable plug with screws is provided for each stereo channel output. Strip approximately 1/4 inch of insulation from the end of each wire and carefully twist the strands of each conductor together. Be sure not to cut the individual strands or twist them off. All strands must be used for optimal performance. Insert the wire into the plug and screw the screws very tight. Inspect that no wire “hairs” that can short circuit are not in the plug.

Correct polarity connections are important to maintain proper speaker phasing. When speaker phasing is correct, all speakers move in and out at the same time preserving the imaging of the program material. Out-of-phase connections mean that some turn off, check your speakers to verify that they are operating properly. If all other potential sources of trouble check out properly, contact Knoll for further assistance.

Run the cables to speaker locations. Do not coil any excess cable, as this may become an inductor that creates frequency response variations in your system. Lastly, connect the wires to the speakers, again being aware of proper polarity. Remember to connect the negative, or black wire, to the matching terminal on the speaker. The positive, or red wire should be connected to the matching terminal on the speaker.

Note: While most speaker manufacturers follow industry convention of using red terminals for positive connections and black terminals for negative, some manufacturers may vary from this configuration. To ensure proper phase connections, and optimal performance, consult the identification plate on our speaker terminals, or the speaker’s manual to verify polarity. Contact the speaker’s manufacturer if you do not know the polarity of your speakers.

Keypad Connection

The GSZ67 outputs can be controlled by the MR164 keypad and/or an external controller or computer (using the RS232 port), so keypads may not be needed.

More than one or two keypads can be used in a zone and nine (9) is the maximum number of MR164 keypads per GSZ67 allowed.

Note: MR164 keypads are not designed for outdoor use, high humidity, high temperatures or any extremes.

The MR164 contains an almost all brand infrared repeater and most functions can be controlled by the Knoll RB12 remote control. RB12 commands can easily be stored in a learning remote.

The MR164 is connected to the GSZ67 with CAT5 or CATe wire. Each keypad can have a home run or be daisy chained on one wire. If you daisy chain one zone and another zone on one wire you may lose some infrared functionality.

Each room or zone has a unique IR pass-thru port as indicated on the rear of the

GSZ67. In addition there is an all room IR pass-thru port. If you combine two or more rooms or zones on 1 CAT5 wire the ability to individually split infrared signals will be lost. Each keypad has two RJ45 connectors that are both inputs and outputs for daisy chaining keypads together. Five of the eight CAT5 wire conductors are used.

Note: 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.

We recommend the T568A wiring method, which is shown below.

The functions of each wire connection are also shown.

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.

2. Connect all of the up to seven sources using short as possible good quality

RCA patch cords to GSZ67 #1 source inputs.

3. Connect GSZ67 #1 source outputs to GSZ67 #2 source inputs using good quality, short as possible RCA patch cords.

Page Inputs

On the rear of the GSZ67 there is a single page input on a stereo 3.5mm jack. This is for connection of external paging equipment like our DC111 door chime generator.

The DC111 generates door chime sounds that are unique for the front, side and rear doors. These paging sounds can be heard via the GSZ67 throughout the home even if the GSZ67 is switched off or playing some other content.

11

To activate the paging override a 5-25 DC volts is applied and the override occurs when the voltage is present. The paging occurs about 1 second after the voltage is applied and continues until the voltage is removed. Call our technical support for further details.

Trigger output

The mono 3.5mm connector on the rear of the GSZ67 supplies 12 VDC (maximum

100 mA) when any or all of the zones are turned on.

Pass output

The PASS output port on the rear of the GSZ67 is for data signals going to an infrared generator. This is a stereo 3.5mm connector and is connected to all keypads in the system.
