■ Connection between electronic instrument and playback equipment
This connection example shows use of the 1204 as an effect device for electronic instruments. When using the unit
in a monaural configuration, connect only the L jack. The balance between the original sound of the instrument and
the effect sound is adjusted by the MIX LEVEL control.
■ Connection to send/return jacks of a mixer
This connection example shows use of the 1204 in the send/return loop of a mixer to which instruments or other
sound sources are connected.
In this case, the balance between the original sound of the mixer (DRY) and the effect sound produced by the 1204
(WET) is normally adjusted at the mixer. Therefore the MIX LEVEL control of the 1204 should be turned fully
clockwise, so that only the WET sound is returned to the mixer.
■ Connection between microphone and playback equipment
This connection example shows use of the 1204 as an effect device for vocals. Use a dynamic microphone with an
impedance of 600 ohms. Plug the microphone into the MIC IN jack on the front panel of the 1204. If connected to
a rear-panel INPUT jack, the volume level will not be sufficient. Normally, the signals fed to the INPUT jacks on
the rear panel and the MIC IN jack on the front panel will be mixed and processed by the same effect. An
exception is the Vocoder effect. When this effect is active, the signal from the MIC IN jack on the front panel and
the right INPUT jack on the rear panel is mixed and used as envelope signal for controlling the Vocoder. Only the
signal from the left INPUT jack on the rear panel is effect-processed and heard as sound. (The balance between the
signals from the MIC IN jack and right INPUT jack can be adjusted with the EDIT 2 control.)
■ Using two effects in parallel
The 1204 allows the simultaneous use of two effects in parallel. This is possible with the effects in bank B marked
with a "/" on the display. This connection example shows how to use such effects independently in a parallel
configuration.
