Печатать страницуStereo/Mono:
A three-position back panel switch is used to select Stereo, Bridge-Mono
or Parallel-Mono mode.
Input/Output Data
Input Connector:
Balanced XLR connector.
Input Impedance
: Nominally 20k ohms, balanced; 10 k ohms, unbalanced.
Output Connector:
Two sets of color-coded 5-way binding posts (for banana plugs,
spade lugs or bare wire) and two sets of speakon connectors.
Output Impedance:
Less than 10 milliohms in series with less than 2 microhenries.
DC Output Offset:
Less than 10 millivolts.
Output Signal Modes
Stereo:
Balanced, two-channel.
Bridge-Mono:
Balanced, single-channel. Channel 1 inputs are active; Both channel
volume controls are available.
Parallel-Mono:
balanced, single-channel. Channel 1 inputs are active; Both channel
volume controls are available.
Protection
DP Series amplifiers are protected against shorted circuits or mismatched
loads, overloaded power supplies, excessive temperature, chain destruction
phenomena, input overload and high frequency blowups. They also protect
loudspeakers from input and output DC and provide protection from turn-on/turn-off
transients.
If operating conditions are unreasonable, the patented circuitry proportionally limits the
drive level to protect the output transistors, particularly in the case of elevated
temperature. A thermal switch imbedded on the heat-sink protects the output device
from overload. In the rare event that a transformer overheats, the thermal switch turns
the power off, waits until the unit has cooled to a safe temperature and then resets itself.
Turn On:
Five second delay with no dangerous transients. Contact DIGISYNTHETIC
Audio Inc. if you need to change the delay.
Construction
Durable black finish on steel chassis with special "flow-through" ventilation from rear
panel to front panels.
Cooling
: Internal heat sinks and two 80mm high speed low noise cooling fan with auto
speed-control forced-air cooling for rapid, uniform heat dissipation.
