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

eZi-DA66 Installation Manual Revision 1.2 Page 11
SPEAKER INSTALLATION – IMPORTANT
IMPORTANT: The Multizone Controller amplifiers are capable of driving 4 Ω to 8 Ω speaker loads in stereo mode and 8 Ω loads in bridge mono mode.
Never connect more than two 8 Ω speakers wired in parallel to a single amplifier channel in stereo mode. Never connect more than one 8 Ω speaker to a
single channel in bridge mono mode. Never connect the Left & Right channels of the amplifier together. Never combine the – negative channels of the
amplifier together. Improper speaker installation can damage the amplifiers and void the warrant . If ou are unsure how to connect speakers to the
Multizone Controller alwa s contact a qualified technician or contact iLED before connecting speakers to the amplifiers.

SPEAKER INSTALLATION – PRE AMP OUT SPEAKER INSTALLATION – 100V LINE
example powered sub woofer example 100v line
The eZi-DA66 Controller provides 6 x stereo unbalanced line
level PRE-AMP outputs which correspond to the 6 x zone
outputs. PRE-AMP outputs can be used to connect powered
subwoofers to a zone or additional amplifiers to expand the
available power in a large zone or multiple zones.
The eZi-DA66 Controller provides 6 x stereo unbalanced line level PRE-AMP

used to connect powered subwoofers to a zone or additional amplifiers to
expand the available power in a large zone or multiple zones .

eZi-DA66 Installation Manual Revision 1.2 Page 13
CONNECTING SOURCES
The Multizone Controller provides 6 x stereo unbalanced line level source inputs which can be accessed b an zone. Input 1 can be used as a paging (all
zones) input or a part mode (all zones) input. When a source is connected to input 1 and 12VDC is applied to the PA-IN jack (3.5mm tip+ sleeve -), source 1
will be broadcast in all zones. If there is no DC voltage applied to the PA-IN jack then source 1 will act like all the other 5 sources and broadcast onl when a
zone selects source 1. Alwa s use good qualit shielded RCA cables to connect sources to the Multizone Controller and keep RCA cables as short as possible
to avoid RF interference.
INFRARED EMITTER OUTPUTS
This s stem has the abilit to repeat IR signals from each speaker zone to control the source devices. The IR signal from the Master Controller to the
source device requires IR emitters (not included) connected to the Master Controller via a 3.5mm TS plug. The IR repeater function supports single-band IR
signals in the 38KHz range onl . To install an IR emitter, insert the 3.5mm plug for the emitter into the appropriate IR emitter jack. Position the emitter
bulb so that it is within range and has a clear line-of-sight to the source device(s). If the emitter cord is not long enough, ou can use an 3.5mm TS or TRS
extension cable to extend its reach.

12VDC TRIGGER OUTPUTS
6 x 12VDC trigger outputs which correspond to the 6 x Multizone Controller zones are provided. When a zone is powered ON b pressing and holding the
SELECT button on the Multizone Controller ke pad for 3 seconds the corresponding zone sends 12VDC to the trigger output jack. When the zone is
powered OFF the routed 12VDC signal is disengaged. Triggers can be used to automaticall power peripheral equipment ON/OFF with the Multizone
Controller zones. The Multizone Controller also provides a master control 12VDC trigger output which sends 12VDC to the CONTROL OUT jack when an
zone is powered ON. The 12VDC CONTROL OUT signal is disengaged when all zones are powered OFF.

RS232 PORT
DB9 Female RS-232 serial port connection located on the back panel of the Multizone Controller provides 2 wa serial communications. Refer to eZi-DA66
RS232 serial protocol document for detailed instructions. The RS232 port pins are shown below with a few examples of cables.
HD MATRIX RS232 PORT – ONLY AVAILABLE ON EZI-DA66-HD MODELS
DA-66-HD models have a s ereo mini jack serial por moun ed below the DB9 main serial port. This provides control of external HD video matrix
switchers. Each time a source is changed in a zone from the ke pad or external RS232 command, the serial command for the selected matrix switcher will
be transmitted on this port allowing the HD video to follow . Refer to eZi-DA66-HD RS232 serial protocol document for detailed instructions.
