STATUS INDICATORS
These indicators provide information about the integrated power
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 connection is correct, please contact your
dealer.
When the LIMIT LED lights, this is an indication that the power ampli-
fier 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 constantly lit, this can result in sound degra-
dation and you should reduce the output level.
The PROTECT LED will light when one of the power amplifier’s compre-
hensive protection circuits like the temperature overload 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 existing short-
circuits. If necessary unplug the SPEAKON-type loudspeaker cable
from the appliance. Maybe you have connected 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 profes-
sional standard SPEAKON high-performance connection. This mecha-
nical and electrical secure connection 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 damage 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.
