he Crown Macro-Tech i Series amplifiers continue the Macro-Tech legacy of unparalleled sonic accu-
racy and detail, putting sound quality above all else. Their patented, cutting-edge Class-I circuitry gets 
more power out of an amplifier with less waste. Each model features a Global Power Supply designed 
to deliver maximum power in any country. The i Series offers studio-quality analog signal processing 
with built-in load, line voltage, input and output monitoring. Standard Ethernet networking via System 
Architect
provides integrated monitoring and control to give system operators access to the system from
any location.

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 out-
put): 
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 
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 suppliled 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 
Neutrik® 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 
connector accepts an RJ-45 connector for 
HiQnet™ networking. Next to the connector is 
a yellow LINK ACT indicator that shows net-
work 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 flash-
es 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.
