intercom system and to external audio equipment or

to the AUDIO LINE connectors (input & output), also
on the rear of the PS 260T.

The electronic circuitry of each interface is powered
by the 30V DC power supplied via the intercom party
line.
The unbalanced signal on the audio wire of the ASL
party line appears on the PS 260T audio output
connector after being converted to a balanced signal.
The signals brought to the audio input connector are
placed on the audio wire of the intercom line
connector.
Two-stage side tone trimmers avoid that audio input
signals appear at the audio output connector. The
input/output separation is better than 30 dB from 200
Hz to 20 kHz. The built-in test tone generator assists
to adjust or check the side tone levels.
The audio inputs and audio outputs of the PS 260T
are transformer balanced.
After unpacking the unit please inspect for any
physical damage to the unit, and retain the shipping
carton and relevant packing materials for use should
the unit need returning.
If any damage has occurred, please notify your
dealer so that a written claim can be initiated. Please
also refer to the warranty section of this manual.
Faults arising from misuse, unauthorized
modifications or accidents are not covered by this
warranty. If the unit is faulty, it should be sent in its
original packing to the supplier or your local ASL
dealer, with shipping prepaid. A note must be
included stating the faults found and a copy of the
original suppliers invoice.
There are no separate power connections to install
since the necessary DC voltages are derived from
the ASL party line.
The PS 260T is fully protected against wiring
mistakes (reverse power) or short circuit in the
interconnecting cables.
