Product Description:

MA-5002VZ Specifications

The following applies to 120-VAC, 60-Hz units in Stereo mode with 8-ohm loads and an input sensitivity of 26-dB gain unless otherwise specified. Specifications for units supplied outside the U.S.A. may vary slightly at different AC voltages and frequencies.

Power Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo, 4 to 16 ohms in Bridge-Mono and 1 to 4 ohms in Parallel-mono mode.

Voltage Gain to 1-kHz, 8-ohm rated output;

132:1 6% or 42 dB 1 dB gain at 0.775-volt sensitivity. 71:1 12% or 37 dB 1 dB gain at 1.4-volt sensitivity. 20:1 3% or 26 dB 0.25 dB gain at the 26-dB gain setting.

Required AC Mains: 50 or 60 Hz; 100-, 120-, 200-, 208-, 230-, 240-VAC (10%).

AC Line Current ,
Current, voltage and frequency requirements are provided on the units back panel.

At Idle: All units draw 90 watts or less.

AC Line Connector: 10 AWG cordset with NEMA TT30P plug is provided on 120 VAC, 60 Hz North American units.

Performance

Frequency Response: 0.1 dB from 20 Hz to 20 kHz at 1 watt.

Phase Response: 10 degrees from 10 Hz to 20 kHz at 1 watt.

Signal-to-Noise Ratio,A-weighted:
Better than 105 dB below rated 1-kHz power.

Total Harmonic Distortion (THD): 1-kHz rated power, 0.05% or less true THD.

Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.05% from rated power to 35 dB below rated power at 8 ohms.

Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz.

Controlled Slew Rate: (Slew rates are limited to useful levels for ultrasonic/RF protection.) Greater than 30 volts per microsecond.

Controls

Compressor: A three-position back-panel switch is used to control each channels input compressor. The "fast" setting provides an attack time of 4 milliseconds and a release time of 300 milliseconds; the "slow" setting provides an attack time of 12 milliseconds and a release time of 600 milliseconds; the "off" setting defeats output-driven compression.

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

Input Ground Lift: A two-position back-panel switch located on the PIP2-FXQ used to isolate the input audio signal grounds from the AC (chassis) ground.

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

Loudspeaker Offset Integration: A two-position back-panel switch for each channel used to turn the loudspeaker protection circuitry on and off. The circuitry protects against DC, off-center woofer cone movement, and unwanted subsonic and ultrasonic frequencies.

Sensitivity: A three-position back-panel switch for each channel used to select input sensitivity: 0.775 volts or 1.4 volts for standard 1-kHz power, or a 26 dB voltage gain.

Stereo/Mono: A three-position back-panel switch used to select Stereo, Bridge-Mono or Parallel-Mono mode.

VZ Mode: A four-position switch for each channel inside the front panel used to control the switching mode of the VZ power supplies.

Indicators
Enable: An amber front-panel LED that shows the on/off status of the low-voltage power supply.

Signal/IOC: A green front-panel LED for each channel that flashes to show amplifier output. If a channels output waveform differs from its input by 0.05% or more, the indicator flashes brightly to show distortion.

ODEP: An amber front panel LED for each channel that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available reserv...
