The Ashly SRA-TR2 60W/70V transformer option allows the Ashly SRA-120 power amplifier
to drive 70 volt distributed sound loads. Mount the transformer option directly next to an SRA-120
for connecting to the amplifier outputs. Separate transformers are used for channel one and channel
two. Transformer input wires are pre-stripped for connecting to the SRA-120 binding posts, while
70 volt transformer outputs are factory wired to #8 screw teminals for speaker wire connections. The
following diagram shows the proper use of the SRA-TR2. Please note that the SRA-TR2 is not
compatible with other power amplifiers, only the Ashly SRA-120.
