Speaker Line Matching
Transformers
Line transformers adapt
conventional 8ohm speakers
for use with multi speaker
commercial systems. High
efficiency design provides
insertion loss of less than
0.6dB, with frequency
range of 50Hz~15KHz. A
single unit is compatible with both 70.7V and 25V
systems, for greater flexibility, and models are available
with 10W and 30W RMS capacity. Secondary
impedance is 8ohm. Primary taps: •10W model: 0.63W,
1.25W, 2.5W, 5W and 10W •30W model: 5W, 10W,
15W, 20W and 30W

slight rise above 2KHz for improved
speech intelligibility. Long life DPDT
leaf switch provides choice
of push-to-talk (with lock
capability) or lift to
talk operation. It is
manufactured to take normal
abuse and retain its performance over a
long life. Features: •Molded non skid feet •Rugged die-

100 Watt Speaker
Matching Transformer
Single coil autoformer
allows high power matching
of 8ohm or 16ohm speakers
to 70V or 100V distributed
commercial systems. It may also be used to convert
8ohm speakers to 16ohm, allowing larger numbers of
speakers to be used in a conventional 8ohm
installation. Wide frequency response makes this ideal
in situations where sonic quality is critical. Color-coded
22AWG connections are 12" in length. Specifications:
•Power capacity: 100W RMS •Frequency response:
35Hz~19KHz (±1dB) •Taps (ohms): 8, 16, 50, 100, 200,
400, 800, 1600, 3200 •Taps (70V): 100W, 50W, 25W,
