Dynacord 800 A CONTROLS

LEVEL

This control sets the output volume of the SUB800A in a range

between -∞dB and +10dB. The internal power amplifier provides a

nominal input sensitivity of +6dBu.

STATUS INDICATORS

These indicators provide information about the actual operational

state of the SUB800A’s internal power amplifier.

SIGNAL indicates that an audio signal is present at the input and

that it is output.

LIMIT When lit this indicator signals that the internal power ampli-

fier is actually operated at the borders of clipping. Short-term

blinking is uncritical, because the amp’s audio limiter keeps distor-

tion under control, so that the sound is unaffected. Input overdrive,

which results in sound degradation, is a probable cause for a

continuously lit indicator. To prevent this from happening, reduce

the input level.

TBC lights when the power amplifier’s “Thermal Brain Circuit” is

activated. During dynamic peaks the integrated power amplifier is

capable of producing output levels that clearly exceed its stated

nominal output capacity. Therefore, the SUB800A employs a TBC-

circuit (Thermal Brain Circuit), which simulates the thermal behavior of the speaker’s

voice-coil, automatically reducing the energy fed to the speaker system on the

occurrence of thermal overload.

PROTECT Lights when one of the multiple comprehensive protections, e.g. against

thermal overload, HF, DC or Back-EMF of the power amplifier is activated. Preven-

ting the woofer from being damaged, it is shutoff via relays in the protect mode.

Additionally, the input level is being reduced. During power-on the PROTECT LED

lights for approximately 2 seconds, which is normal. This only indicates that all

protection circuitry has been activated properly.

POWER switch

Mains switch for switching the SUB800A’s power ON or OFF. The switch lights after

turning the power ON. Make sure that the mains cord is correctly connected if the

switch is not lit upon turning the power on. If the mains cord is correctly connected

and the mains switch does not light upon power-on, please contact your local dealer.

Mains fuse

During normal operation the mains fuse of the SUB800A only blows at the occur-

rence of a malfunction. Exchanging the fuse is only permissible using a fuse of the

same type (current, voltage and release characteristic). In case the fuse blows

frequently, please contact your local dealer.

Mains connector

Mains connection is established via a PowerCon connector. A 5m long mains cord

with PowerCon plug is supplied.
