DIGITAL POWER AMPLIFIER
of your amplifier to drive a transformer to drive 100V speaker
systems. This mode applies a highpass filter to channel 2. Filter
characteristics: 12 dB/oct at 50 Hz. Butterworth characteristic.
This setting increases amplifier stability when using a 100 volt
transformer on output 1.
• CH1 BRIDGED CH2: both amps are used in bridge. Audio signal
from input 1 is used.
• Combination CH1 SUB – TOP CH2 with CH2 TRAFO LOAD: this
combination allows a low impedance subwoofer to be used
with 100 volt top speakers. Audio signal from input 1 is used.
This setting increases amplifier stability when using a 100 volt
transformer on output 2.
• CH1 TRAFO LOAD with CH2 TRAFO LOAD: a highpass filter is
applied to channel 1 and 2 to ensure that low frequencies are
filtered. Filter characteristics: 12 dB/oct at 50 Hz. Butterworth
characteristic. This setting increases amplifier stability when
using 100 volt transformers on the outputs.
