Frame To Gnd Link; Speaker Lines Connection; Trigger Connector - Optimus DA-500D2 Manual De Instalación Y Funcionamiento

DA-500D2
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 speakers
(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 60 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.
