6 Specifications

The following applies to units in Stereo mode with 8-ohm loads and
an input sensitivity of 26 dB gain unless otherwise specified.

Standard 1 kHz Power: refers to maximum average power in
watts at 1 kHz with 0.1% THD.

Full Bandwidth Power: refers to maximum average power in
watts from 20 Hz to 20 kHz with 0.1% THD.

120 VAC, 60 Hz Units: refers to amplifiers with dedicated trans-
formers for 120 VAC, 60 Hz power mains.

International Units: refers to amplifiers with special multi-tap
transformers that are configurable for several AC mains voltages
and line frequencies (some are labeled 601, 1201 and 2401).

Performance

Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1
watt (see Figure 6.7).

Phase Response: ±10 degrees from 10 Hz to 20 kHz at 1
watt (see Figure 6.10).

Signal-to-Noise Ratio: 20 Hz to 20 kHz: Better than
100 dB below full bandwidth power. A-weighted: Better
than 105 dB below full bandwidth power.

Total Harmonic Distortion (THD): Less than 0.05% at
full bandwidth power from 20 Hz to 1 kHz increasing lin-
early to 0.1% at 20 kHz.

Intermodulation Distortion (IMD): (60 Hz, 7 kHz) Less
than 0.05% from 163 milliwatts to full bandwidth power.

Damping Factor: Greater than 1,000 from 10 Hz to 400
Hz (see Figure 6.8).

Crosstalk: See Figures 6.11, 6.12 and 6.13.

Slew Rate: Greater than 13 volts per microsecond.

Voltage Gain: 20:1 ±3% or 26 dB ±0.25 dB at the maxi-
mum level setting (also see Section 4.4).

Macro-Tech

600: 54:1 ±12% or 35 dB ±0.5 dB at 0.775 volt

sensitivity; 30:1 ±12% or 30 dB ±0.5 dB at 1.4 volt sensitivity.

Macro-Tech

1200: 64:1 ±12% or 36 dB ±0.5 dB at 0.775 volt

sensitivity; 36:1 ±12% or 31 dB ±0.5 dB at 1.4 volt sensitivity.

Macro-Tech

2400: 83:1 ±12% or 38 dB ±0.5 dB at 0.775 volt

sensitivity; 46:1 ±12% or 33 dB ±0.5 dB at 1.4 volt sensitivity.

Power

Output Power:

The following are guaranteed minimums

for standard 1 kHz power from 120 VAC, 60 Hz North
American units. For more information or specs on interna-
tional units, see the power matrices that follow.

1035

watts into 4 ohms.

Load Impedance: Safe with all types of loads. Rated for 2 to
16 ohms in Stereo, 4 to 16 ohms in Bridge-Mono and 1 to 4
ohms in Parallel-Mono mode.

Required AC Mains: 50/60 Hz; 100, 120, 220, 230 and 240
VAC (±10%) units are available. All draw 100 watts or less at
idle. Current, voltage and frequency requirements are pro-
vided on the unit’s back panel (also see Section 7).

Amplifiers don’t create energy. The AC mains voltage and
current must be sufficient to deliver the power you expect.

Controls

Enable: A front panel push button used to turn the amplifier
on and off.

Level: A front panel rotary control for each channel with 31
detents used to control the output level.
