SPEAKER WIRE TERMINATION
Install the eight supplied Phoenix connectors into the audio zone outputs on the
AD-8x. Connect the positive and negative wires for each audio channel output,
keeping the proper orientation of positive and negative signal for each speaker
connection. Typically, two-conductor speaker wire uses red to denote positive
and black to denote negative. Four-conductor wire can also be used. This has
four separated wires in one outer jacket, making it possible to run a single
speaker wire to a zone for its pair of speakers. This type of wire typically uses
red and black for one speaker and white as positive and green as negative for
the second speaker.
CAUTION: Do not short speaker wires together if they are connected to
the AD-8x, as damage to the unit may result.
CONNECTING LOCAL AUDIO SOURCES
The AD-8x has eight sets of RCA audio inputs for connecting up to eight
sources.
• Trim Control: The Trim Control dials on the AD-8x are used to equalize
signal levels of each input source to ensure that switching between inputs
will result in the same output level. The Trim Control is initially set at zero
(no attenuation).
NOTE: Adjusting the Trim Control dial will adjust the signal level of both
the local source input and remote source input simultaneously. Thereby
adjusting the output supplied to the Pre-Out jacks set in either FIX or VAR
mode and to the speaker jacks.
• Local/Mix/Remote Switch: This switch determines which input source
will be used (Local or Remote).
NOTE (Mix Mode): While it is possible to have audio sources wired to
both the local and remote inputs, and the input switch set to “Mix”, it is
important that both sources (local and remote) not be “on” at the same
time otherwise the signal will be blended.
• Loop Outputs: These buffered loop outputs allow each source to be
distributed to multiple AD-8x systems if more than 8 output zones are
required.
