Micro-Tech 600/1200/2400 Power Amplifiers

6 Specifications

The following applies to units in Stereo mode with with both channels
driven into 8 ohm loads and an input sensitivity of 26 dB unless other-
wise specified.
Standard 1 kHz Power: refers to maximum average power in watts at
1 kHz with 0.1% THD+noise.
Full Bandwidth Power: refers to maximum average power in watts
from 20 Hz to 20 kHz with 0.1% THD+noise.
120 VAC, 60 Hz Units: refers to amplifiers with dedicated transform-
ers for 120 VAC, 60 Hz power mains.
International Units: refers to amplifiers with special multi-tap trans-
formers that can be configured for several AC mains voltages (some
may be labeled 601, 1201 or 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: A-weighted, better than 105 dB below
full bandwidth power. From 20 Hz to 20 kHz, better than
100 dB below full bandwidth power.
Total Harmonic Distortion (THD): Less than 0.05% at full
bandwidth power from 20 Hz to 1 kHz increasing linearly to
0.1% at 20 kHz.
Intermodulation Distortion (IMD): (60 Hz and 7 kHz 4:1)
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.
Controlled Slew Rate: Greater than 13 volts / ms.
Common Mode Rejection (CMR): At rated full bandwidth
power, better than 70 dB from 20 Hz to 1 kHz falling linearly
to better than 50 dB at 20 kHz.
Voltage Gain: 20:1 ±3% or 26 dB ±0.25 dB at the maxi-
mum level setting (also see Section 4.4).
Micro-Tech 600 : 55:1 ±12% or 35 dB ±1 dB at 0.775 volt
sensitivity; 31:1 ±12% or 30 dB ±1 dB at 1.4 volt sensitivity.
Micro-Tech 1200 : 64:1 ±12% or 36 dB ±1 dB at 0.775 volt
sensitivity; 34:1 ±12% or 31 dB ±1 dB at 1.4 volt sensitivity.
Micro-Tech 2400 : 83:1 ±12% or 38 dB ±1 dB at 0.775 volt
sensitivity; 46:1 ±12% or 33 dB ±1 dB at 1.4 volt sensitivity.

Parallel-Mono mode:
2,080 watts into 1 ohm.
1,605 watts into 2 ohms.
1,035 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: 100, 120, 220 and 240 VAC (±10%),
50 and 60 Hz units are available. All units draw 90 watts or
less when idle. AC mains current, frequency and voltage
requirements are provided on the unit's back panel (also
see Section 7).
Important: Your amplifier must have sufficient AC power.
Amplifiers cannot create energy—they require proper volt-
age and current to deliver the power you expect.
