APPLICATIONS
EXAMPLE FOR HARMONICA SOLO
Connect the microphone for the harmon-
ica to the INPUT 1. If you use a CD player
etc. as an accompaniment, connect it to
the INPUT 3 and 4. Thus you can control
the tone for the harmonica and the ac-
companiment separately.
The input terminal of this unit is a phone
jack. The output terminal of the portable
CD player is often a stereo 1/8
˝
phone jack,
you can connect it by using a set of con-
nection cables with a stereo 1/8
˝
phone
plug and 2 RCA plugs and 2 adaptors with
a RCA jack and a 1/4
˝
phone plug.
The output level of the microphone is
rather small, so set the [VOLUME 1]
knob a little high. That of the CD player is
rather high, so set the [VOLUME 3] and
[VOLUME 4] a little low.
If you want to add reverb effect only on
the harmonica but not on the accompa-
niment, turn [OFF] the [REV.] switch be-
forehand.

If the volume of one unit is not sufficient, you can increase the power by connecting
the LINE OUT jack to the [INPUT 1] jack of another SPA-150R-L, prepared as a sub-
sidiary unit. In this case, set the [VOLUME 1] at 2 and the [MASTER VOLUME] at 5
on the slave unit.
Set the TONE controls at center on the slave unit for avoiding undesirable sound
change.
