The Crown
180MAx shall be a tuner-mixer-amplifi er for commercial and
industrial audio. It shall provide 4-ohm and constant-voltage outputs (25V and
70V).
The 180MAx shall have 4 inputs (each with a volume control) and one 80W
power amplifi er.
Specifi cations
The 180MAx shall have the following specifi cations:
Minimum guaranteed power into 4 ohms or 25V/70V output: 80W maximum
power at 1 kHz with 0.5% THD. Frequency Reponse (at 1 watt from 4-ohm tap,
70 Hz - 19 kHz): ±1 dB. Frequency Response (at line out, 20 Hz to 20 kHz): ±1
dB. Power Bandwidth (at 4-ohm tap, 2 dB below maximum 1 kHz power): 50 Hz
to 20 kHz with < 0.5% THD. Signal to Noise Ratio (ref. to rated power, master
volume at minimum): 85 dB. DC Output Offset: < ±5 mV. THD: Less than 0.5%
at rated power at 1 kHz. Input Sensitivity (for full output at maximum gain): Bal-
anced mic inputs 3 mV, balanced line inputs 800 mV, RCA connectors 400 mV,
Isolated telphone input 75 mV. Input Impedance (nominal): Mic 400 ohms, line
100 kilohms, RCA 50 kilohms, Telephone 600 ohms. Crosstalk: –70dB at 1kHz.
Line Output Level (nominal): 1V into 10 kilohms. Phantom Power: 15 VDC.
AC Line Voltages Available: 120V, 60 Hz. Line voltage tolerance +10%, –20%.
Operating Temperature/Humidity: 0° C to 40 degrees C at 95% relative humidity
(non-condensing). Storage Temperature: –20° C to 85°C.
Front Panel Controls and Indicators
Front panel controls and indicators shall include the following:
Power Switch: Pushbutton on-off switch. Input Volume Controls: Four
detented potentiometers with knobs. Input 1: Microphone/line (switchable)/
telephone, Inputs 2 and 3: Line, Input 4: XM Radio. Tone Controls: Bass and
Treble non-detented recessed potentiometers on each input channel, Bass
±10 dB at 100 Hz, Treble ±10 dB at 10 kHz. XM Tuner Menu Button: Selects
Direct, Preset, or Category mode. XM Tuner Category Buttons: Scrolls through
categories (rock, classical, news, country, etc). XM Tuner Scroll Knob: Lets
you scroll through channels and select them. XM Tuner Display: LCD screen
displays XM channel data (channel number, channel name, artist name, song
title), 16 station presets and signal strength. Power Indicator: Blue LED indi-
cates power on. Input Signal Presence Indicator: Green LED illuminates when
input signal exceeds –24 dBu (line) or –70 dBu (mic). Output Signal Presence
Indicator: Green LED, illuminates when output signal level exceeds 100 mV
(45 dB below full power) from the 4-ohm tap. Clip Indicator: Red LED on
output illuminates at threshold of audible distortion. Output Volume Control:
Detented potentiometer with knob.
Back Panel Controls, Connectors and Indicators
Back panel controls, connectors and indicators shall include the following:
Reset Switch: Resets the circuit breaker that protects the power supply. MOH
1V Level Control: Trim pot adjusts level for Music-On-Hold 1V output. MOH
1W Level Control: Trim pot adjusts level for Music-On-hold 1W output. MOH
Signal Presence Indicator: Flashes when MOH signal is present. MOH Source
Switch: Switches between Input 3 or XM, and routes the source to MOH 1V
Line Out and MOH 1W connectors. MOH 1W Select Switch: Feeds 1W MOH
signal either to amplifi er output or internal speaker. MOH 1V Line Output RCA
Connectors: Two RCA connectors (mono) for 1-volt output (in parallel with
600-ohm connectors, so they are isolated). MOH 1W Line Output Connector:
3-pin Phoenix connector provides Music-On-Hold signal of approximately 1
watt. MOH 1V Line Output Phoenix Connector: 3-pin Phoenix connector, 600-
ohm transformer-isolated output, provides Music-On-Hold signal of approxi-

mately 1 volt. Phantom Power Switch: Turns phantom power on or off for
Input 1. Mic/line Switch: Selects mic-level or line-level signal for Input 1. Link
In/Out Switch: Slide switch. When set to IN, any signal applied to the Amp
Input connector will be mixed with the input signal(s); when set to OUT, only
the signal from the Amp Input Connector will appear at the amplifi er output.
Amplifi er Output Connectors: 4-position terminal strip with COM (Common), 4
ohms, 25V and 70V terminals; accepts up to 10 AWG crimp-on terminal forks;
non-touch cover included. XM Radio Stereo Line Out Connector: Dual RCA
jacks for stereo music out from XM Radio tuner. Preamp Line Out Connector:
3-pin balanced Phoenix-type connector; post master, pre-VCA; level controlled
by master volume control. Output VCA Connector: 4-pin Phoenix-type connec-
tor for two VCA control lines of +10 VDC and ground; compatible with Crown
1-VCAP and 4-VCAP modules. Priority Connector: 3-pin Phoenix-type connec-
tor for push-to-talk mic switch; contact closure activatges ducking; ducking
does not affect Music-On-Hold outputs or XM stereo line out. Active Indicator:
LED illuminates when VOX ducking is active. VOX Threshold: Trim pot adjusts
how loud the voice must be before ducking occurs; can be set for no ducking.
Priority Release Control: Trim pot adjusts release time of VOX ducking. Mic/
Line Input Connector (Input 1 only): 3-pin Phoenix-type, balanced. Line Input
Connectors (Inputs 2 and 3 only): 3-pin Phoenix-type, balanced. Dual RCA
Input Connector: For stereo music signals, unbalanced, summed together, two
connectors per input for inputs 1, 2 and 3. TEL Input Connector: Transformer-
isolated 600-ohm input, summed into Input 1 for paging from a telephone
system. Amp Input Connector: 3-pin Phoenix-type, high-impedance balanced.
Used to link an additional mixer to the mixer-amplifi er; can be used to connect
an external processor. AC Power Inlet: Detachable IEC. XM Radio Antenna
Input: Connects to the XM antenna cable.
Miscellaneous
Cooling shall be by convection. Included protection mechanisms shall be cur-
rent limiting, over-temperature thermal cutout, and DC-fault load protection.
Included accessories shall be a power cord, detachable rack ears, screws for
rack ears, non-touch cover for output connectors, Phoenix-type connectors,
spade lugs, XM antenna, and remote control. Optional accessories shall be a
1-VCAP remote volume control.
