Output Connections

Line Out
This output uses a phono connection
The Line Out connector provides an output (1V) for connection to slave amplifiers for larger
systems where more power is required and is connected post master volume.
Tape Out
This output uses a phono connection
Two phono sockets are available. These are connected together internally and provide a
fixed mono output, independent of the master gain control.
Loudspeaker Out
It is possible to connect 100V line loudspeakers or 8Ω low impedance loudspeakers to the
music output only. Under no circumstances must the two types be mixed. The output is
overload protected.
Two loudspeaker outputs are available – 'Music & Speech' and 'Speech Only'.

'Music & Speech' gives a permanent output of all signals passing through the
amplifier. Three terminals are provided. COM gives a common (0V) connection
for both 100V and 8Ω operation. Connect the loudspeaker circuit to 100V if
100V line loudspeakers are being used or connect to 8Ω if low impedance
loudspeakers are being used. Do not connect any circuit where the load
impedance is less than the minimum source impedance (for example, if wiring
to the 8Ω terminal, the total load impedance must not be less than 8Ω).

'Speech Only' gives an output during a priority condition only.
terminals are 100V line terminals only. They are useful when an area needs
coverage only from a priority source such as a paging microphone.
Loudspeaker Loading
To allow sufficient transient overload margin it is suggested that the output load should not
exceed approximately 80% of the rated power output.
