POWER AMPLIFIER SECTION:
General:
Bi-amp system with independent,
class-D, bridge-tied load outputs
crossed over at 3KHz (24dB/octave
filter)
Amplifier frequency response = 20 –
20KHz
Power Consumption:
USA/Japan: 100 – 120vac 50/60Hz =
90 Watts
Europe/Other: 220 – 240vac 50/60Hz
= 90 Watts
Rated Power:
*Measurements taken at 120vac line;
channels measured independently;
ratings at <5% THD
104 Watts continuous into 8 ohm,
series woofer load (400Hz sine wave)
104 Watts continuous into 8 ohm,
planar tweeter (5KHz sine wave)
PREAMP SECTION:
Channel 1 / Channel 2:
Input impedance = 3M ohm (1/4"
jack); <10K ohm (balanced XLR)
Phantom power = +48V (XLR) / +9V
(1/4" jack)
Nominal signal input level = -11.7dBu
Maximum signal input level =
+4.69dBu
Channel 3 / Aux In:
Input impedance = 330K ohm (front
1/4" jack); 10K ohm (rear, summed
phono jacks)
Nominal signal input level =
-6.90dBu
Maximum signal input level =
+20dBu
DIGITAL SECTION:
32-bit floating point DSP
Audio converter = 24-bit
