ASR History 02 (English)................(346KB)
The technique of the ASR Emitter II exclusive B:
• two channel amplifier in the acrylic casing with input selector and volume
control.
• Class A/B technology with 20 Toshiba special Audio-MOSFETS with high
impulse-capacity.
• Mounting bars of the output Transistors made from massive brass for low
resonance.
• Volume control with relay attenuator in 1dB-Steps with balance and input
level adjustment.
• 25 mm LED-Display available in yellow or blue as operational indicator,
adjustable in many ways
• 6 high-level-inputs switched with relay, plus 1 direct input, 1 record
output.
• Gold plated massive brass RCA-sockets with Teflon isolation. Massive
silver-wires for all signals.
• large 100 amperes binding post for cable-shoes and 4 mm banana-plugs.
• 1 plug in slot for Phono – pre amplifier circuit board or balanced input.
• Protection-circuits against overload, Clipping, Short-circuit, Overheating
and DC Offset.
• Circuit board with especially strong copper, parts of the two channels in
mirror-symmetrical order.
• 2 external power supplies with 3 PM transformers and energy-management,
separate rectification for each of the 8 voltages with 2x 32 Schottky
rectifiers.
• Especially stable power supply casing of high-quality, very stable steel
sheet metal.
• Low loss Neozed high load fuse built in the power supply unit.
• stable industrial power connector from Harting for the connection to the
amplifier-part.
• Double shielded connection-cables to the amplifier-part 2m long, on wish
other lengths.
• Power cable ASR Magic cord 150 cm with low loss 21A power connector at the
power supply.
• high-quality ASR Design remote control made from Corian for all functions.
Additionally equipment of the ASR Emitter II Exclusive
• Military ceramic input IC AD 843 SQ, buffering capacitors with total
886.000 uF.
• Balanced input for CD with switchable input impedance.
• feets made from of massive brass for the amplifier unit available in
chrome or gold.
• 2 Power supplies with improved equipment for higher performance. The 2x 3
PM transformators are equipped with higher magnetic flux kernel-sheet metal,
rectification with 56 Schottky rectifiers.
• A battery power supply for the input stage with 400.000 uF additional
Buffer available as an Option.
