with critical or low impedance
* High stability driving capacitive loudspeaker loads
* Motor-driven ALPS high grade potentiometer
* Channel separated professional class A input circuits
* Extremely linear class A current mirror driver stages and altogether 8 to very high
quiescent current adjusted power mosfets determine lowest distortion level
and a sweet tempered harmonic spectrum
* Separated power supplies for left and right poweramp-sections, separated power
supplies for preamp-section and remote control, fast recovery diodes,
gigantic total power supply capacity of more than 80 000 Microfarads

input selection. The transmitter is learnable/programable
* Noble, high glossy black acryl front, massive, solid high-end-casing with resonance
absorbing polished chrome feet
* Every device comes along with "its own" original measuring record of the frequency response,
further measuring records are available on reques

Specifications:
Inputs: 2 line level inputs (cinch)
Gain error (left to right channel): < 0,7 dB from 0 to -40 dB
Input resistance: nominal 100 kOhms, inputs AC-coupled
Damping factor at 1 kHz: switchable: 470 or 250 (measured with 8,00 Ohm resistor at 10 Watts)
Output power (sinus) at 1kHz: 210 Watts (29,0 Veff) into 4 Ohms each channel,
140 Watts (33,5 Veff) into 8 Ohms each channel
(THD+N = 0,2 %, with nominal mains voltage)
Risetime/falltime: 4,75 µsec into 4 Ohms load (square wave 20 kHz, 12 Vss, measured from 10 % to 90 %)
Max. DC Output offset: +/- 22 mV
Crosstalk: 84 dB (input 2,0 Veff, opposite channel with 40 Ohms loaded, (at 1 kHz, left/right, right/left)
test setup grounded, output load 4 Ohms each channel)
Signal to noise ratio: -94 dB (A-weighted, ref. to 6,325 Veff, inputs with 40 Ohms loaded, test setup grounded)
Total harmonic distortion (THD+N): into 4 Ohms: 0,0075 %, into 8 Ohms: 0,005%
(measured at 1 kHz and 10 Watts, test setup grounded,
measuring bandwidth 22 Hz - 22 kHz)
Quiescent current: left: 276 +/- 3 mA, right: 262 +/- 3 mA (after a warm-up time of 90 min, at nominal mains voltage minus 3 V AC)
(values for items with "predelay")
left: 270 +/- 3 mA, right: 262 +/- 3 mA (after a warm-up time of 90 min, at nominal mains voltage minus 3 V AC)
(values for items without "predelay")
Security circuit disconnects loudspeakers:
* when device is switched on for a delayed switch-on of both outputs
* if an internal fuse blasts
* at break-down of an internal supply voltage
* at an interruption of mains voltage
* at too high levels of very low frequencies or at DC offset at an output
* at too high levels of very high frequencies or oscillating at an output
After end of a break-down both outputs will work again.
