Specifications
Performance
Frequency Response (at 1 watt, 20 Hz - 20 kHz
into 8 ohms): ±0.25 dB.
Signal to Noise Ratio (below rated full-bandwidth
power, A-weighted): > 110 dB.
Total Harmonic Distortion (THD) (at 2 watts into 8
ohms): < 0.1%.
Total Harmonic Distortion (THD) Plus Noise (at
full rated power): < 0.35%, 20 Hz to 20 kHz.
Intermodulation Distortion (IMD) (60 Hz and 7
kHz at 4:1, from full rated output to –30 dB):
< 0.35%.
Damping Factor (20 Hz to 100 Hz at 8 ohms):
> 5000.
Crosstalk (below rated power, 20 Hz to 1 kHz):
> 80 dB.
Common Mode Rejection (CMR) (20 Hz to 1
kHz): 55 dB, typically >70 dB.
DC Output Offset (shorted input): < ± 3 mV.
Input Impedance (nominal): 10 kilohms balanced,
5 kilohms unbalanced.
Maximum Input Level: +20 dBu typical.
Network: Onboard HiQnet™, compatible with
standard 100 Mb Ethercom hardware.
Load Impedance: (Note: Safe with all types of
loads)
Stereo: 1/2/4/8/16 ohms.
Bridge Mono: 2/4/8 ohms.
Input Sensitivity (referenced to 8 ohm rated
output): 1.4V, 32 dB gain, and 26 dB gain.
Voltage Gain (referenced to 8 ohm rated output):
MA-5000i: 37.1 dB to 22.2 dB
MA-9000i: 37.9 dB to 23.0 dB
MA-12000i: 39.3 dB to 24.5 dB
Required AC Mains: Universal AC input, 100-
240VAC, 50/60 Hz (±10%). Maximum AC mains
voltage 264VAC.
AC Line Connector: Five cordsets supplied with
amplifier (USA, UK, European, Australia, India).
Front Panel Controls and Indicators
Bridge Mode Indicator: Amber LED illuminates
when the amplifier is set to Bridge-Mono mode.
Ready Indicator: Green LED, one per channel.
On (bright): Ready.
On (dim): Onset of compression.
Off: Thermal failure.
Signal Indicators: One green LED per channel.
Solid green: Input signal is above –40 dBu.
Bright green: Channel’s output signal has reached
the onset of audible clipping.
Power Indicator: Blue LED indicates amplifier has
been turned on and AC power is available. The
LED will flash when the AC line voltage is 10%
above or below the nominal rated value.
Data Indicator: Yellow LED on front panel indi-
cates network data activity. Data indicator flashes
only when the amplifier is polled for data, or is
polled to see whether it is online
Power Switch: Push-on/push-off switch with
built-in green AC mains present indicator.
Volume Control: Precision detented attenuator
with 31 steps, press-and-hold mute function.
Volume Control LED Ring: A ring of green LEDs
around each volume control show the position of
the control. Entire ring flashes when channel is
muted. Can be converted to be a level meter.
Back Panel Controls, Indicators and Con-
nectors
Power Cord Connector: Detachable 20 amp IEC
inlet. Cord locks with supplied cord retention clip.
Voltage range is indicated above IEC inlet.
Reset Switch/Circuit Breaker: If the current draw
of the amplifier exceeds safe limits, this breaker
automatically disconnects the power supply
from the AC mains. The switch resets the circuit
breaker.
Output Connectors: Two high-current, 50A Neu-
trik®Speakon®NL4MLP (mates with NL4FC or
NL4), one per channel. Ch 1 Speakon®is wired
with Ch 1 and Ch 2 outputs for use with single
4-conductor cable. Two pairs of high-current,
60A color-coded 5-way binding posts (for banana
plugs, spade lugs or bare wire).
Analog Input Connectors: A 3-pin female XLR
connector for each channel.
Analog Loop Thru Connectors: Two male XLR
passive analog loop through.
Mode Switch/Indicator: Sets amplifier to Stereo,
Bridge, or Input Y mode. OFF=Stereo, YEL=Bridge,
GRN=Y.
Network Connector: This Neutrik®Ethercon con-
nector accepts an RJ-45 connector for HiQnet™
networking. Next to the connector is a yellow
LINK ACT indicator that shows network activity,
and a green 100Mb indicator that shows a 100Mb
network connection.
Data Indicator: Yellow LED on back panel indi-
cates network data activity. Data indicator flashes
only when the amplifier is polled for data, or is
polled to see whether it is online.
Preset Indicator: Green/yellow LED flashes to
signal the number of the current preset. LED is
green if current preset is active, or is yellow if cur-
rent preset is modified.
Input Sensitivity Switch: Three-position switch
providing 1.4V, 32 dB, and 26 dB settings for both
channels.
