How to Connect
Amplifier Settings
Two side-by-side amplifier channels are used for each zone. One side is set to amplify the Left channel
of a stereo signal and the other side is set to amplify the Right side of a stereo signal. In our diagram,
channel 1 is set to amplify the Left channel and channel 2 is set to amplify the Right channel for the
speakers in Zone 1.
Level: Conveniently located on the front panel, our multi-channel amplifiers include a separate level
knob for each amplifier channel. Rotate the knobs clockwise to independently increase the power
output of each channel. Typically, volume knobs will be set between the 3 o’clock and maximum posi-
tion, although lower levels are sometimes used to intentionally limit the volume in certain rooms (you’re
welcome, parents). Please note, however, that intercom volume is also limited by this setting.
Input Selection Switch: Set to “Line”.
L, L+R, R Switch: When the “Line” input is used, this switch is inactive so the setting is irrelevant. How-
ever, you might want to set odd numbered channels to Left (L) and even channels to Right (R) just to
make it easier to recall which Line Output from the Lync Controller is being sent to each channel.
Bridge Switch: Since you are not bridging the two channels, make sure the Bridge Switch is off (far left
position). See the owner’s manual for the amplifier for instructions on bridging adjacent channels to
achieve even higher power (but with fewer amplifier channels) when necessary.
On - Auto On - Trigger Switch: Setting this switch to “Trigger” is best when using Lync with a
multi-channel amplifier. For Lync 6, see page 11 for more details; for Lync 12, see page 12.
WARNING: The six (6) recessed switches labeled “Bridged” on the back of
the multi-channel amplifier are factory pre-set in the left, Non-Bridged posi-
tion. They are recessed and pre-set for a very important reason – Because
improper use can damage the amplifier.
Bridging is NOT used to create a mono signal from a stereo signal. Typical
use of the multi-channel amplifier does NOT require Bridging of channels. If
Bridging is improperly used, it could result in permanent damage to the am-
plifier, your volume controls and your speakers.
DO NOT
change the Bridge
switches without FIRST contacting HTD at 1-866-483-2834 or
Damage resulting from improper use of Bridging may not be covered by the HTD Warranty.
