DAX66 INSTALLATION — OVERVIEW
Install the DAX66 in a well-ventilated location; do not block the vents on the sides or top of the chassis, proper ventilation is required for
normal operation. Do not expose the unit to excessive dust and do not allow dust to build up on the unit and block the vent holes in the
chassis. Do not place the DAX66 above or below heat-generating components such as another audio amplifier. Be sure to leave at least
2 inches of space to the sides of the chassis with open air flow above and below the unit. Due tothe weight of the unit, we recommend
OVERVIEW:
1. The DAX66 can be mounted in an equipment rack using the included rack mount kit.
2. Always disconnect AC power before making connections to the DAX66.
3. Use good quality 12 or 14 AWG stranded copper speaker wire for all speaker connections.
4. Use good quality cable for connection of the keypads to the master controller/amplifier; we recommend Cat5e to connect keypads.
5. The DAX66 uses a keypad hub; all keypads will connect to the hub. Install the keypad hub close tothe master controller/amplifier.
For ease of installation, the keypads and the keypad hub are fitted with quick-disconnect screw terminal blocks.
6. The keypad hub connects easily to the master controller/amplifier using a standard Ethernet patch cable.
NOTE: When attaching
a keypad to an electrical
box, use a screwdriver
to reduce the chance of
damage to the keypad.
NOTE: Set the Address of each keypad using the DIP switches on back of the keypad. ZONE-1 ZONE-2 ZONE-3

DAX66 INSTALLATION — KEYPADS
INSTALLATION Keypads
Use high quality Cat5e/6 cable betweenthe controller/amplifier andthe keypads. Proper installation techniques will guarantee that the
keypads will work properly up to 600 feet from the controller/amplifier. The use of terminal blocks on the keypads and keypad hub
ultimately reduces the frustration associated with terminating UTP cable with RJ45 plugs. The PCB is labeled 1 ~ 6 at the location
corresponding to the terminal blocks. Attach the conductors in the same order on each end of the cable. See illustrations on the
previous page.
• Strip the insulation from the UTP (Cat 5e cable) about three inches. Don't be concerned that too much insulation has been
removed since the wire will be hidden in the wall behind the keypad.
• Remove approximately 1/4" of insulation from the conductors and insert into the terminal block. Tighten the screw terminal on
the block to hold the wire in place. Do not over tighten the screw to avoid stripping out the terminal.
• Attach the terminal block to the mating connector on the keypad or the keypad hub.
Use standard electrical boxes or low voltage ringsto mount the keypads and keypad hub. Mountthe keypad hub less than 7 ~ 10 feet
from the controller/amplifier. Connect the keypad hub tothe master controller/amplifier using a standard Ethernet patch cable.
NOTE: Always follow local building codes and use proper electrical boxes and low voltage rings.

DAX66 INSTALLATION — SPEAKERS
INSTALLATION — Speakers
Use good quality 12-14 AWG stranded copper speaker wire. Most jurisdictions require the use of CL2 rated in-wall speaker wire, refer to
your local building code enforcement office for the proper cable type for your installation. If speaker wires must be run parallel to AC wires,
keep the speaker wires and AC wires at least 10 inches apart. If you must cross AC wires, always cross at a 90 degree angle.
The DAX66 amplifiers are capable of driving 4 ~ 8 ohm speaker loads in stereo mode, and 8 ohm loads in bridge mode. Never connect
more than two 8 ohm speakers wired in parallel to a single amplifier channel in stereo mode. Never connect more than one 8 ohm
speaker to a single channel in bridge mode. Never connect the Left & Right channels of the amplifier together or combine the (–) negative
channels of the amplifier. Improper speaker installation can damage the amplifiers and void the warranty. If you are unsure how to
connect speakers to the DAX66, contact a qualified technician.
Remove the terminal block connector and make sure that all contacts are open by turning each set screw counter clockwise. This helps
insure thatthe speaker wire will not fray when inserted into the terminal.
INSTALLATION: Connecting 8 ohm speakers to the DAX66 in STEREO MODE
Set the amplifier mode switch to STEREO. Remove approximately 5 inches from the cable jacket, strip 1/4" of insulation from the speaker
wire, and twist the copper strands. Insert the speaker wires into the connector per the label below the output terminals and tighten the set
screws. Repeat for the remaining zones.

INSTALLATION: Connecting 8 ohm speakers to the DAX66 in BRIDGE MODE
In BRIDGE mode the amplifier LEFT and RIGHT outputs are combined into one large MONO amplifier, thus doubling the output
power to 50 watts with a minimum speaker load of 8 ohms.
Remove approximately 5 inches from the cable jacket, strip 1/4" of insulation from the speaker wire, and twist the copper strands.
Insert the speaker wires into the connector per the label below the output terminals and tighten the set screws. Repeat for the
remaining zones.
It is permissible to mix STEREO and Bridged MONO outputs on one DAX66.

DAX66 INSTALLATION — PRE-AMP OUTPUTS
Using the DAX66 PRE-AMP OUTPUTS
The DAX66 provides six stereo, unbalanced, line level PRE-AMP outputs, which correspond to the six-zone outputs. The 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 DAX66 can be used as the master controller in large commercial audio systems with constant voltage 25/70V amplifiers connected
to the PRE-AMP outputs.
The PRE-AMP output levels are variable and are controlled from the DAX66 keypad, Infrared remote, or RS232 from an automation
system. For best performance, the PRE-AMP output cables should be less than 25 feet long and be high-quality, shielded cables.

DAX66 INSTALLATION — CONNECTING SOURCES
Connecting Source Components to the DAX66
The DAX66 provides six source inputs that can be accessed by any zone. Inputs 1 ~ 4 are stereo, unbalanced, line level source inputs
via RCA style female connectors. Input 5 provides a connection for a personal audio device or PC sound card via the 3.5mm stereo
jack. Input 6 provides one S/PDIF input for a CD, DVD, cable, or satellite box via the Toslink jack, as well as a second 3.5mm jack.
The 3.5mm stereo jack on input 6 takes priority over the Toslink connector; do not connect cables to both the Toslink and 3.5mm jack
the same time.
Input 1 can be used as a paging or global; all-zones, input. When a source is connected to input 1 and 12Vdc is applied to the PA-IN
jack (tip positive), source 1 will be broadcast to all zones. If there is no DC voltage is applied to the PA-IN jack, source 1 will operate
like normal.
Infrared Emitter Outputs
The DAX66 has an IR repeater system built-in and each source has a corresponding Infrared (IR) emitter output. The IR emitter output
is tied to the corresponding source device, or all (global) source control. Program a universal remote to operate all six of the input devices.
Point the universal remote at the DAX66 keypad to transmit the IR control codesthroughthe DAX66 tothe source devices. With an IR
emitter connected to an IR EMITTER output jack and the emitter placed over the source device IR receiver window, the source devices
can be controlled from any zone.
