The Monitoring System; General Instructions - Burmester Classic Series Owner's Manual

THE MONITORING SYSTEM

The monitoring system of the 956 MK 2 functions outside of the signal path. When the amp is
on, this watchdog circuit constantly checks for errors with respect to temperature, DC offset
and voltage overloads.
Temperature In the event that one or both channels of the amplifier exceed their maximum allowable temperature the
overheat protection switches the output relais off and the POWER LED (3) goes out. The unit is switched
into stand - by mode. As a precaution, we recommend turning the volume down and waiting awhile
before turning the 956 MK 2 back on by pressing the POWER - button (2). The 956 MK 2 can only be
switched back on after the temperature has fallen below the allowable limit.
DC offset If the DC component at the speaker terminals of the 956 MK 2 exceeds the allowable limit, the speaker
relais are switched off. When this happens we recommend lowering the volume level. The 956 MK 2
will re-enable the speaker outputs automatically as soon as DC offset falls within the allowable limits.
Voltage overload If the peak voltage at the speaker outputs of the 956 MK 2 exceeds the allowable maximum the speaker
outputs are automatically switched off. If this happens we recommend lowering the volume and waiting.
The 956 MK 2 will re-enable the speaker outputs as soon as the voltage falls below the upper limit.

GENERAL INSTRUCTIONS

CAUTION: Before opening the housing cover the AC cord must be unplugged. Danger of an electric shock!
Lightning strikes During the summer months, malfunctions often occur due to voltage spikes in the power lines after
lightning strikes. Completely unplugging the power cord offers the only effective protection. Merely
switching the 956 MK 2 off using the AC mains switch (7) does not suffice since voltage spikes are able
to arc over separated contacts.
Interconnect cables We supply custom - made balanced as well as unbalanced interconnect cables of any length to ensure
the best sound quality of the power amp 956 MK 2. The impedance of our cables is ideally matched with
all BURMESTER audio components. For the cleanest power supply we recommend our triple - shielded
power cord BURMESTER - POWER.
Fuses The fuses are located behind the safety lid of the AC voltage selector (9). They should be changed
by an expert only.
CAUTION: Before opening the safety lid of the AC voltage switch the AC cord must be unplugged. Danger of
electric shock!
Optional MONO adapter cables (14) for MONO operation of the 956 MK 2
accessories BI - AMP adapter cables (15) for BI - AMPING operation of the 956 MK 2
