Line In
Insert both RCA plugs into the RCA jacks when using a stereo input. The left and right channels are combined so no
program material is lost. If the source is monaural, either RCA jack can be used. The Line In volume control is used
to increase or decrease the level of the input signal.
Line Out
The two RCA jacks are used to connect to the input of another piece of equipment such as a tape recorder, mixer or
another amplified speaker. The outputs are monaural and volume level will depend on the volume of the source. For
example, the tape or CD player level is controlled by the tape/CD volume control. Line out is independent of the Master
Volume Control.
Tone Controls
The separate base and treble controls provide a wide range of adjustment for increasing or decreasing either the bass or
treble from “flat” frequency response. The center or “12 o’clock” position is flat.
Speaker Mute Switch
Engaging this switch will cut off the sound of all speakers, internal and external, except as explained in the section under
“PA919PS operation”.
Voice Priority
This feature is used for voice override of the music program when using a microphone. The “ducking” circuit attenuates
the music when a person speaks into the microphone. After a 3 second delay in the speech, the music returns to the
previous level.
