Wired Microphones
There are two (2) independent combination XLR/1/4” jacks for using microphones with cords. Each
jack has a volume control, MIC 1 and MIC 2 which control the loudness of the wired microphones. Also
each has a “Voice/Music” switch. On “music” program the sound is full fidelity, while on “voice” the
sound is tailored to give maximum projection while limiting battery drain.
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.
There is also a 3.5mm LINE IN jack available. The Line In volume control knob 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 CD/USB media player level is controlled by the
DISC/TB 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 decreas-
ing either the bass or treble from “flat” frequency response. The center or “12 o’clock” position is flat.
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.
Speaker out
Two 1/4” phone jacks for Switched and unswitched speaker output signals to connect to external
speakers. Switched output disengages main speaker, unswitched output divides output between
main speaker and passive speaker.
