3 Overview
The PT-1SPDIF is a high quality digital audio converter that accepts a digital
audio S/PDIF input and converts it to an optical TosLink® audio output.
The PT-2SPDIF is a high quality digital audio converter that accepts an
optical TosLink® audio input and converts it to a digital audio S/PDIF.
The PT-1SPDIF and PT-2SPDIF output the same data stream as the input,
without any conversion. In this way all existing and even future audio formats
are supported. Both are:
12VDC fed
Housed in a small enclosure
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
Avoiding interference from neighboring electrical appliances that
may adversely influence signal quality and positioning your PT-1SPDIF
and/or PT-2SPDIF in a location free from moisture and away from
excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
