An RCA jack is provided near the output terminal strip for connection to a

WMT

1

A line-matching transformer. A 600-ohm, balanced telephone level output

signal can be obtained by plugging the RCA connector of the WMT

1

A line-matching

transformer into this jack and taking the output signal off of the WMT

1

A line-

matching transformer screw terminals (see Figure 9).This is useful for dividing a long
line when connecting to remote equipment.

When all output connections are made, remove the appropriate knockout on the
input cover. Replace the cover and tighten the screws while dressing the wires
through the knockout hole.

An external power amplifier can be used with the TPU250 amplifier. You must first
add a resistor voltage divider to the telephone amplifier, as illustrated in Figure 8.
Connect a patch cord to the high-level/high-impedance input of the booster
amplifier.
