Connecting The Amplifier to the Lync6

How to Connect
(CONT.)
Use the Variable Line Outputs on the Lync to connect to the Line Inputs on the amplifiers for each zone. We
include six 3’ shielded stereo patch cables with the Lync for this purpose. The diagram above shows the recom-
mended connection to our DMA-1240 12-channel amplifier.

Amplifier Settings
Two side-by-side amplifier channels are used for each zone. One side is set to amplify the Right channel of a stereo
signal and the other side is set to amplify the Left side of a stereo signal. In our diagram, channel 1 is set to amplify the
Right channel and channel 2 is set to amplify the Left channel for the speakers in Zone 1.
Level: Our multi-channel amplifiers include separate level knobs for each channel. Turn the rotary Level knob clockwise
to increase the power output of each channel. In most cases, setting this knob around the 2:00 position will achieve the
amplifier’s maximum rated power output level. You can artificially add gain to a weak line level input signal by turning this
level beyond this point, but in most cases it is not necessary and not recommended. Best Practice: with the Level knob all
the way down (counter-clockwise), set the LyncPad volume level to 60 (max). Next, using a strong input signal (such as
from a DVD player or TV set-top box), have a friend slowly adjust the Level knob(s) up (clockwise) until the volume level
in the zone is as loud as you would ever want it. Leave the Level knob at this setting. This is the most efficient way to
operate your amplifier and also prevents a zone from accidentally operating at too loud of volume.
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. However, you might
want to set odd numbered channels to Right (R) and even channels to Left (L) just to make it easier to recall which Line
Output from the Lync is being sent to each channel.
