STATUS INDICATORS
These indicators provide information about the integrated po-
wer amplifier's actual status.
When the AM12 is powered-on, the POWER will light. In case
the LED does not light after switching the power on please
make sure that the mains cord is plugged in correctly. When
the POWER LED still does not light although the mains con-
nection is correct, please contact your dealer.
When the LIMIT LED lights, this is an indication that the power
amplifier is operated at its limit. Short-term blinking is not
critical, since the integrated limiter circuit controls occurring
distortion within the power amplifier. When the LED is con-
stantly lit, this can result in sound degradation and you should
reduce the output level.
The PROTECT LED will light when one of the power amplifier's
comprehensive protection circuits like the temperature over-
load protection, HF-protection, DC-protection, and the Back-
EMF-protection is activated. In Protect Mode, the loudspeaker
outputs are muted via the speaker relays and the audio signal's
input level is automatically attenuated to protect the power
amps from being damaged. When the AM12 enters Protect
Mode, first check the EXTENSION SPEAKER output for exi-
sting short-circuits. If necessary unplug the SPEAKON-type
loudspeaker cable from the appliance. Maybe you have con-
nected more than one speaker cabinet to the output.
When switching the power of the AM12 on, the PROTECT LED
will light for approximately 2 seconds. This is normal, indicating
that the entire protection circuitry is operational.
POWER
1. Mains connection via rubber connector
2. Mains fuse socket
3. Mains-switch for Power-On/Off
EXTENSION SPEAKER
Full-range loudspeaker output for the connection of passive
cabinets like the DYNACORD M12 or C15SUB. The output is
carried out as a professional standard SPEAKON high-perfor-
mance connection. This mechanical and electrical secure con-
nection complies with all safety standards allowing the use of
high-quality speaker cables with diameters of up to 4 x 2.5mm.
The Extension SPEAKER output provides the possibility for
connecting a single cabinet with an impedance of 8 ohms.
Connecting several cabinets does not necessarily cause da-
mage to the integrated power amplifier but it might activate the
internal protection circuitry.
WARNING:
The speaker output terminals are marked with a symbol
" ", which signifies that these terminals present a
shock hazard to the user.
Make connections to these terminals as described in the
owner's manual.
Plugs, jacks, and high-quality loudspeaker cables are available
from DYNACORD's accessory assortment.
