Balance Control Characteristics

The balance control attenuates the signal from the source, so that the left and right bass frequencies (summed together and

reproduced in the woofer channel) will also respond to the balance control.

Example:

If an audio signal of a voice speaking English is fed to the left (A) input and a voice speaking Spanish is fed to the

right (B) input, then the left speaker channel will reproduce the midrange and high-range frequencies of the

English speaking voice, the right speaker channel will reproduce the midrange and high-range frequencies of the

Spanish speaking voice, and the woofer speaker channel will reproduce the summed (combined) low-range

frequencies of both voices.

If the balance control is rotated to the left (English), then the Spanish speaking voice in the right speaker channel

will diminish in volume and the Spanish speaking voice in the woofer speaker channel will also diminish.

Note that if the balance control is rotated completely to the left, the volume in both the left speaker channel and

left woofer speaker channel will increase slightly to maintain overall output level. See the simplified diagram

below for placement of the balance control in the audio amplifier circuit.

The converse of the above is true if the balance control is rotated to the right.
