Macro-Tech 5002VZ Power Amplifier

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. Contact your
Crown representative for full details).
Power
Output Power
Note:See the Minimum Guaranteed Power table in Fig-
ure 6.1 for the output power specifications under a vari-
ety of conditions.
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: 20:1 ±3% or 26 dB ±0.25 dB at the
maximum level setting. 132:1 ±12% or 42 dB ±1 dB at
0.775 volt sensitivity. 71:1 ±12% or 37 dB ±1 dB at
1.4 volt sensitivity. Also see Section 4.4.
Required AC Mains: 50 or 60 Hz, 100, 120, 200, 208,
230, 240 VAC (±10%). Draws 90 watts or less at idle.
Current, voltage and frequency requirements are pro-
vided on the unit's back panel.
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. (see Figure 6.3).
Phase Response: ±10 degrees from 10 Hz to 20 kHz
at 1 watt.(see Figure 6.6).(see Figure 6.6).
Reference Manual
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
@ 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.
(see Figure 6.4).
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 channel's 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 loud-
speaker protection circuitry on and off. The circuitry
protects against DC, off-center woofer cone move-
ment, and unwanted subsonic and ultrasonic fre-
quencies.
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: This amber front panel indicator shows the
on/off status of the low-voltage power supply.
