250W, 6 Channel Mixer Amplifier
AMIS250
Description
The AMIS250 is a 6 channel, 250 watt mixer amplifier suitable for rack or desk mounting. The ampli-
fier is a self contained compact unit of solid steel construction. 
Inputs
The AMIS250 has six universal input channels with separate level controls. Each channel will accept
balanced or unbalanced microphone, line and auxiliary inputs. The unit has industry standard XLR
microphone sockets and dual RCA auxiliary sockets for each channel. An electronically-balanced
600 ohm telephone input for paging is also provided. An insert point is also featured on the rear
panel for those applications where an additional EQ or feedback exterminator may be required.
Outputs
The AMIS250 features 70 volt and 4 ohm isolated transformer outputs, plus a tape recorder output
by means of dual RCA sockets. A balanced 700mV XLR output is also provided to feed up to 6
power amplifiers.
3 Band EQ
The AMIS250 includes a 3 band equaliser (Bass, Middle and High), giving the user a wider range of
tone controls for high level music or difficult voice applications. 
Tone Generator
The AMIS250 comes standard with an in-built four tone generator module. Tones include Bell, Pre-
announce Chime, Alert Tone and Evacuate Tone. Any of these tones may be activated from a sim-
ple contact closure on the rear panel of the amplifier.
Muting
VOX muting is standard on the AMIS250. A mic or line signal on channels 1 or 2 will mute channels
3, 4, 5 and 6. The muting function can be disabled via an internal link.
Phantom Power
Phantom Power (18V DC) is available from all mic inputs. A rear panel phantom power on/off switch
is also provided.
Protection
Internal current limiting protects the amplifier from both overload and overdrive conditions.
Australian Monitor Installation Series amplifiers feature a protection network that provides greater
stability and performance. Our amplifiers are recognised worldwide for their
reliability and this is due to the extensive levels of current limiting which pro-
tect the amplifiers from both overload and overdrive conditions.
