1160A

The Crown

® 

1160A shall be an amplifi er for commercial and industrial 

audio. It provides 4-ohm and constant-voltage outputs (70V and 100V).

The 1160A has 1 input and one 160W power amplifi er for single-zone 
systems.

Specifi cations

The 1160A shall have the following specifi cations:

Minimum guaranteed power into 4 ohms or 70V/100V output: 160W maxi-
mum 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 maxium 
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): 800 mV.  Input Impedance (nominal): 
100 kilohms. Minimum Load Impedance: 100V output 160 ohms, 70V 
output 80 ohms, 4-ohm output 4/8 ohms. Crosstalk:  –70dB at 1kHz. Line 
Output Level (nominal): 1V into 10 kilohms. AC Line Voltages Available: 
100V  50/60 Hz, 120V  60 Hz, 220V  50/60 Hz, 230V  50/60 Hz, 240V  
50/60 Hz. Operating Temperature/Humidity: 0 degrees C to 40 degrees 
C at 95% relative humidity (non-condensing). Storage Temperature: –20 
degrees C to 85 degrees C. 

Front Panel Controls and Indicators

Front panel controls and indicators shall include the following:

Power Switch: Pushbutton on-off switch. Master Volume Controls: One per 
output channel, detented potentiometer with knob. Tone Controls: Bass and 
Treble non-detented potentiometers on each channel, Bass ±10 dB at 100 
Hz, Treble ±10 dB at 10 kHz. Power Indicator: Blue LED indicates power on. 
Output Signal Presence Indicator: Green LED, one for each input channel, 
illuminates when input signal exceeds 100 mV (45 dB below full power) 
from the 4-ohm tap. Clip Indicators: Red LED, one per output channel, 
illuminates at threshold of audible distortion.

Rear Panel Controls and Connectors

Rear panel controls and connectors shall include the following:

Reset Button: Resets the circuit breaker that protects the power supply; 
220/230/240V units shall have a fuse instead. AC Power Inlet: Detachable 
IEC. Auxiliary Power Input: 2-position terminal strip for 24 VDC (±10%) 
backup power; accepts up to 14 AWG terminal forks. Amplifi er Output 
Connector: 4-position terminal strip with COM (Common), 4 ohms, 70V 
and 100V terminals; accepts up to 10 AWG terminal forks, non-touch 
cover included. Output VCA Connector: 4-pin Phoenix-type connector for 
two VCA control lines of +10 VDC and ground; compatible with Crown 
1-VCAP and 4-VCAP modules. Line Out Connector: One 3-pin balanced 
Phoenix-type connector,  post master, pre-VCA, level controlled by master 
volume control. Amp Input Connector: 3-pin Phoenix-type, high-imped-
ance balanced.  

Miscellaneous

Cooling shall be by convection. Included protection mechanisms shall 
be current 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 con-
nectors, and spade lugs. Optional accessories shall be a 1-VCAP remote 
volume control for one channel, and a 4-VCAP remote volume control for 
four channels.

The dimensions of the amplifi er shall allow for 19 inch (48.3 cm) EIA 
standard (RS-310-B) rack mounting. The amplifi er shall be 3.5 inches (8.9 
cm) high, and 12.2 inches (31 cm) deep behind the rack-mounting surface 
(not including the non-touch cover).

The amplifi er shall weigh 25.3 lb (11.5 kg).

The amplifi er shall be designated the Crown 1160A.
