Frame To Gnd Link; Speaker Lines Connection; Trigger Connector - Optimus DA-500D4 Manual De Instalación Y Funcionamiento

DA-500D4
Class-D amplifier

5.3. Frame to GND link.

This amplifier incorporates a ground to frame link switch. A single frame to ground link should exist
in the installation; in other case ground noise could appear.

5.4. Speaker lines connection

This equipment includes two speaker
line outputs for high impedance (100V).
The total line load must be lower that
amplifier's RMS power.
NOTE: Each channel is independent,
never mix the two lines. The minimum
section is 1.5 mm², but it can be
increased according to the installation
requirements.

5.5. Trigger connector

If the STBY and GND terminals are short cut, the amplifier will
go into standby mode and consumption will be reduced to less
than 80 W.
STBY THRU Output terminal is connected in parallel with
STBY IN.
STATE OUT terminal is 5 Vdc under normal operation, and
open in case of protection or standby. A LED could be used to
have a visual reference when the amplifier goes into one of
these two states. In that case, please, connect it as shown in
the picture. Maximum current 12 mA.
