MULTIPLE STAGES OF PROTECTION
Each pair of channels (or Zone) is individually protected with an operation mode indicated by bi-color LEDs on the front of the
to a short, only the channels that are affected will be turned off. The other zones will continue to play.
GLOBAL A & B AND DIRECT INPUTS
A dedicated input can be assigned to a pair of channels via the channel Line In connection. Each pair of channels can also
receive the right channel, and the even-numbered channels will receive the left channel. This is further indicated by the color of
the channel Line In jacks (odd numbers have white jacks and even numbers have red jacks). A 3 position switch is available for
each channel pair to choose between the line-in and the 2 Global-Inputs.
today’s demanding custom audio installations.
INDIVIDUAL CHANNEL AND GAIN ADJUSTMENTS
Each pair of channels has its own level adjustment which adjusts the maximum output. This allows the output of to be perfectly
matched to its area. It can also serve to provide a limit on how loud each speaker may be allowed to play. Be sure set the
volume at a level that does not clip or cause distortion when the volume is at the maximum level. This can cause damage to the
INSTALLATION-FRIENDLY CONNECTIONS
Each pair of speakers feature a removable speaker wire connector that accommodates up to 14 gauge stranded speaker wire.
The power cord is removable as well, facilitating fast and simple installations. The Global Inputs, Loop Output, and individual
Channel Inputs are all high-quality RCA connectors.
BRIDGING
The power output of adjacent channels can be combined to provide extra power when needed in certain areas.
Maintain an 8 ohm minimum when using bridge mode.
RACK-MOUNTABLE
POWER MODE
Power state can be toggled using the front Power Button, 12V input, or Audio Sensing. The method for power toggle is set by
on the operation of each mode.
Note: The front panel power button is inoperative when the 12V Trigger or Audio Sense power modes are selected.

· Be sure that the unit is in a well-ventilated area that provides adequate cooling.
· Do not block the cooling vents located on both sides of the unit.
· Do not place the unit on carpeting or any similar material.
· Do not install the unit near a source of heat, or in an extremely humid or wet location.

· Allow a minimum of 5” of free air space above the unit.
· Allow a minimum of 3” of free air space on either side of the unit. (Does not apply to rack mounting).
INSTALLATION – GETTING CONNECTED
CAUTION: All connections and switching must be done with the
INPUTS
For line level connections, use high-quality RCA cables that feature low impedance, shielding and high-quality connectors.
SPEAKER OUTPUTS
Use 14-18 gauge stranded two-conductor loudspeaker wire for all high level connections. At each loudspeaker-level connection,
ensure that at least 2 inches of each conductor are separated. Strip away 1/4 inch of insulation from each conductor. Connect the
appropriate conductor to the speaker connection, observing correct polarity.

VERIFYING PHASE
When proper polarity is not maintained, the speakers play at the opposite ‘time’ from each other, or out of phase. The result is
audio with lack of bass and vocals that sound thin or distant.
If during or after calibrating your receiver you suspect the sound is not right and you cannot see any markings on the wire to
verify polarity is correct, try this simple test:
1. Sit in the normal listening position for the system.
2. Play some music with your receiver set to Mono.
Listen to the music and observe the audio.
- Does the bass sound full and even with the other audio?
- Do the vocals sound centered and even in volume?
If any of the answers are YES, follow steps 3 and 4.
3. Turn off your receiver and reverse the connections for one of the speakers.
4. Repeat your test at the same volume level. When the sound has the loudest and best sounding bass, and vocals are centered
and clear, your connections are correct and in-phase.

BRIDGING CHANNELS
There are situations when you may wish to combine two channels into one
through a process known as bridging. The output of the two combined channels
can then be used to power one speaker.
To Bridge Two Adjacent Channels:
2. Set the channel switch to BRIDGED/MONO.
3. Connect the (+) POSITIVE lead of the speaker to the (+)POSITIVE
connection of the EVEN numbered channel.
4. Connect the (-) NEGATIVE lead of the speaker to the (+) POSITIVE
connection of the ODD numbered channel.
5. Connect the output from the source to the LINE IN of the EVEN numbered
channel.
Note:
· DO NOT connect more than one speaker to the outputs of the bridged channel.
· All input selection and volume settings for bridged channels will be controlled by
the RED channel.
· Maintain an 8 ohm minimum when using bridge mode.
