60W, 6 Channel Mixer Amplifier
Description
The SA60 is a high quality system amplifier which can be powered by AC mains or 24 volts DC.
It is sturdily constructed with a solid steel chassis and standard rack mounting front panel.
Generous heat sinking and a conservatively rated 125vA power transformer ensure that the
amplifier comfortably meets specifications.
Inputs
The SA60 features six universal channels with separate channel gain controls. Each channel will
accept balanced microphone or unbalanced line and auxiliary inputs. The unit has industry
standard XLR microphone sockets and dual RCA auxiliary sockets for each channel.
Outputs
The SA60 features 100 volt, 70 volt & 8 ohm isolated transformer outputs. A separate male
XLR socket provides a 700mV (max.) balanced transformer isolated output for connection to
additional power amplifiers. A separate tape recorder output is supplied by means of dual
RCA sockets.
Insert Point
A 6.35mm insert jack between the pre-amp and power-amp stage is accessible on the rear panel. It
is ideal for a Graphic EQ, FBX Feedback Exterminator or any other type of line in/line out processor.
DC Operation
The DC input allows the SA60 to be powered by an external 24 volt battery supply.
Tone Generator
A four tone module (ATC5488) is an optional accessory. The unit plugs in to a receptacle inside
the amplifier. A choice of any one of four tones may be selected including Bell, Pre-announce
chime, Alert tone (AS2220.1) and Evacuate tone (AS2220.1). Any of the tones may be activat-
ed from a remote point by means of external connections which may be wired to the rear panel
of the amplifier. Activation of any tone automatically mutes inputs 2 to 6 of the amplifier.
Muting
The SA60 is equipped with a multi-pin receptacle on the circuit board which accommodates
the optional TX3014 two channel muting module. With the TX3014 installed, signal present on
channel 1 will mute all remaining inputs (2 to 6). When signal is present on channel 2, inputs 3
to 6 are muted. A single channel muting module TX3010 is also available. This unit plugs into
the same socket within the amplifier and will provide muting of channels 2 to 6 when signal is
present on channel 1.
Protection
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 protect the amplifiers from both overload and
overdrive conditions.
