Two-Wire Volume Control
A Rowe innovation, the two-wire volume control simplifies complex installations and reduces cost. A special
preamplifier design permits volume control wiring using any unshielded two-wire cable.
OUTPUT TRANSFORMERS
The output transformers (Figure 1-7) “step up” the power amplifier’s output voltage for 70-volt extension speakers.
The output transformers also provide connections (taps) for selecting different power levels for the speakers.

SPEAKER SYSTEM

mid/high range speaker, a tweeter, and a crossover network.
