High current capability for undistorted output into low impedance loads.
Exceptionally wide bandwidth, independent of negative feedback, improves transient accuracy.
Designed for low distortion and wide bandwidth without high negative feedback, improving dynamic accuracy.
Utilizes discrete electronic circuitry for high performance, surpassing integrated circuits.
100 watts per channel into 8 ohms, 20-20,000Hz, less than 0.06% THD.
10Hz to 70,000Hz at half rated output into 8 ohms.
0.1Hz to 170,000Hz (+0, -3dB).
98dB (IHF-A WTD).
1V/22k ohms.
AC 220/240V, 50/60Hz (General); AC 120V, 60Hz (USA/Canada).
390W (General); 550W (600VA) (USA/Canada).
443 x 135 x 386mm (17-7/16"x5-1/4"x14-3/8").
12.3kg (27lbs.).
Use correct AC voltage and handle the power cord gently to prevent damage or fire hazards.
Place on a firm, level surface away from moisture, heat, cold, vibration, dust, or poor ventilation.
Do not open the cabinet. Prevent shock hazard and consult authorized service for any internal issues.
Disconnect power before moving. Clean with a soft dry cloth; avoid volatile agents.
The 'wait' indicator illuminates for 8 seconds during normal turn-on to protect speakers.
Circuit activates for short circuits or high temperatures, muting the amplifier for protection.
Use high-quality wires. Connect preamplifier output to speaker input. Ensure correct turn-on/off sequence.
Connect speakers with 4-16 ohm impedance using thick, low-resistance, color-coded wires.
