Electrical ratings:
24VDC, 61mA
5VDC, 29mA
Use unshielded twisted pair for high
level amplifier connections. Use
shielded twisted pair for terminals 1
and 2. Use single-conductor wire for
other connections.
Maximum wire length:
Refer to the decibel (dB) loss chart in
the tables below. The wire length
includes the length of the wire from
the amplifier to the ASC-2, from the
ASC-2 to the ZC series of audio cards,
and the wire length in the longest
audio zone served by the amplifier.
ASC-2 Connections and Ratings
4 - 7
High level outputs:
25.2V RMS, 4.0A, 100W max
70.7V RMS, 1.4A, 100W max
Backup amplifier input:
1V RMS max
All wiring must be in accordance with
Article 760 of NEC or the local building
codes.
Electrical connections:
Some signal is lost in the zone wires
due to line resistance. Refer to the
tables below to determine the decibel
loss for various wire gauges and
lengths. A reduction in load reduces
the loss. Use the largest wire size
possible for the smallest loss.
