KEYPADS
The Multizone Controller ke pads are available in white and are designed to be ver eas to use. Five backlit buttons access zone power on/off, volume
up/down, selection of sources 1-6, zone treble, zone bass, zone unmute and zone standb . The backlit LED displa provides visual feedback of levels and
source numbers. The Multizone Controller ke pad also provides an Infrared receiver which allows complete zone control via the included Multizone
Controller-RC hand held remote control. The Multizone Controller IR s stem also sends IR commands to the Multizone Controller master controller IR
output jacks for remote control of our source components. No programming necessar , just touch the ke pad and start pla ing music instantl !

INSTALLATION INSTRUCTIONS - IMPORTANT
The Multizone Controller should be situated in a well-ventilated position. Never block the vents on the sides or top of the chassis. Proper ventilation is
essential. Do not expose the unit to excessive dust. Do not allow dust to build and block vent holes. Do not place the Multizone Controller above or below
heat-generating components such as audio amplifiers. Allow at least 50mm (1U) of space to the sides of the chassis with open air flow above and below.
Before making an connections ensure that eZi-DA66 is powered off and unplugged to prevent personal injur or equipment damage due to electrical
shock.
1. The Multizone Controller can be mounted in an equipment rack using the rack kit that is included.
2. Alwa s disconnect the AC power cord before making an connections to the Multizone Controller. Ensure the Voltage selector above the mains
socket is set on the correct voltage (220V) for South Africa.
3. Use good qualit 2mm
2
to 3mm
2
(12 to 14awg) conductor stranded copper speaker wire for all speaker connections.
4. Use good qualit cat5e or cat6 cable and RJ45 connectors for all Multizone Controller ke pads.
5. The Multizone Controller includes a central ke pad hub. All Multizone Controller ke pads will be home run back the hub. Keep the hub close the
Multizone Controller.
6. Wire all cat5e/cat6 cables exactl the same using TIA/EIA 568A wiring. Do not use crossover cables.
7. Controller ke pads must have their mode dip switches set properl before powering the s stem on.
8. Onl 1 ke pad is allowed per zone.
9. Set the three DIP switches on each ke pad to one of the six addresses listed below. Each Ke pad connected to the same Master
Controller/Amplifier must have a unique address.
10. The address is localized to each Master Controller/Amplifier device. If multiple Controllers are in use, each one will have its own set of ke pads with
the same address numbers as ke pads on the Master Controller.
11. The DIP switches work with ON=logic0 and OFF-Logic1. Zone1 = 001 = (1)ON (2)ON (3)OFF – see detailed explanation and diagram below:
SETTING THE KEYPAD MODE DIP SWITCHES
Each ke pad has a hand mode selection chart on the back as follows: Switch in the UP position is ON or LOGIC 0. Switch in the down position is OFF or
LOGIC1. Switch 1 is the Binar MSB or Most Significant Bit. Use binar value to set the Zone.

KEYPAD WIRING
IMPORTANT: Use a screwdriver to install the ke pad.
Using a power drill can damage the ke pad.
The Multizone Controller ke pad should be mounted in an electrical back box using a screwdriver to tighten. Do not use a power drill to tighten the ke pad
screws. Over tightening can damage the ke pad.
Use a good qualit Cat5e/6 cable and crimp RJ45 jacks on each end of the cables. The RJ45 jack plugs into the back panel of the ke pads and the 6 x RJ45
jacks on the ke pad hub. The Multizone Controller ke pad hub is included in our Multizone Controller kit. Plug the RJ45 jacks into an available jack on
the Multizone Controller ke pad hub. Zone assignment is determined b the MODE dip switches on the back of the Multizone Controller ke pad.

KEYPAD CABLE INFORMATION
Long runs of CAT cable running to various parts of a house makes the s stem susceptible to EMI (Electro Magnetic Interference). The CAT
cables running from the DA-66 to each ke pad operate as antennae’s which in the presence of high EMI such as during a lightning storm
can lead to voltage spikes being introduced into the CAT cable. To mitigate this risk, a Ke pad HUB with surge protection is supplied with
each eZi-DA-66.
INSTALLATION OF KEYPAD HUB - EARTH
The Ke pad Hub is supplied with a lug on a 300mm fl lead. Connect the lug to an screw on the Ke pad Hub and the other end of the fl
lead to an earth point. Please ensure that the earth connection is tested to the earth of the installation – without a reliable earth
connection, the energ generated during a surge will not have a dissipation path resulting in damage to the eZi-DA66 and/or ke pads
INSTALLATION OF KEYPAD HUB – CAT5
The Ke pad Hub has 7 x RJ45 connectors each with heav dut surge protection circuitr connected to a common bus. Connect the ke pads
to the 6 x RJ45 connectors next to each other in order of Zone 1 to 6 from left to right. This is onl for ease of maintenance as the RJ45’s
are not zone dependant (common bus). Connect the RJ45 that is separate from the 6 x RJ45’s to the RK45 Ke pad of the eZi-DA66.
REMEMBER to power the unit off when connecting or changing the Ke pad Zone DIP switches
