Connections
Connecting speakers to your A-400Z
Your A-400Z has no special connection requirements; audiophile grade five-way binding posts are
provided for speaker connections.
• Always
turn off the amplifier before connecting or disconnecting speaker cables or signal
source interconnects.
• Always
verify that your speaker cables are firmly attached, and not shorted to each other or
to any other cables, before powering up your A-400Z.
• Always
use high-quality speaker wire; 16-gauge or heavier.
•
If you must use thinner wire, try to keep the length as short as possible.
•
Be careful to wire all speakers “in phase” (the plus/red terminal on each speaker to the plus/
red terminal on your amp).
•
Try to use wires of equal length and gauge for both speakers in each pair (use the same gauge
and length for both fronts, or for both surrounds; don’t use a long 16-gauge wire for one
speaker and a short 10-gauge wire for the other).
•
If you use stranded cables, use care to avoid short circuits (from stray strands touching).
•
If you are planning to bi-amp your speakers, make sure to remove the jumpers on the input
panel of each speaker. Failure to remove these will damage your amplifier.
Connecting an input source to your A-400Z
Connect a stereo input source to the Low Level Unbalanced Inputs on your A-400Z.
The Master Volume control may be used to match the gain of the A-400Z to your other equipment
if necessary. If you don’t need to adjust the gain, we suggest leaving this control in the fully
clockwise position (turned fully to the right).
The High Pass Filter Switch applies an 80 Hz 12 dB/octave high-pass filter to the audio signal
coming into the A-400Z. This filter affects the speaker outputs on the A-400A but does not affect
the signal appearing at the Line Level Unbalanced Outputs. In a system without a subwoofer this
switch should be left in the Full Range position.
Connecting the Trigger Input and Trigger Output
The Trigger Input accepts a 12 VDC (nominal) trigger signal from another device via a standard
1/8” mono plug. When the trigger is asserted, the A-400Z will switch On; when the trigger is
removed, the A-400Z will return to Standby mode. The Trigger Output sends out
12 VDC whenever the main power to the A-400Z is On (and NOT when it is in Standby mode)
which can be used to switch on other units with trigger capabilities.
