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): > 112 dB.
Total Harmonic Distortion (THD) (at 2 watts into 8
ohms): < 0.1%.
Total Harmonic Distortion (THD) Plus Noise (at
full rated power): < 0.1%, 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): >70 dB typical.
DC Output Offset (shorted input): < ± 3 mV.
Input Impedance (nominal): 20 kilohms balanced,
10 kilohms unbalanced.
Maximum Input Level: +20 dBu typical.
Network: Onboard HiQnet™, compatible with
standard 100 Mb Ethernet 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, 100240VAC (±10%), 50/60 Hz. 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 protection.
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 indicates 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
Connectors
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
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 Connectors: This Neutrik
connector 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 indicates 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 current preset is modified.
Input Sensitivity Switch: Three-position switch
providing 1.4V, 32 dB, and 26 dB settings for both
channels.
