Features of the D4 and their function
 
1. Top panel
 
1. [INPUT 2] mic input jack
 
You can connect a mic to this balanced XLR jack. If 
you use this jack, set the rear panel [INPUT 2] switch 
to “EXT (MIC).”
 
2. MIC (internal mic)
3. INPUT LEVEL [1], [2] knobs
 
These knobs adjust the level of the inputs. The optimal 
setting is the highest level that does not cause the 
LEDs to light.
 
You may hear hum or noise if you raise the INPUT LEVEL [1], 
[2] knob levels when nothing is connected to the input jacks.
 
4. TRACK ASSIGN [1], [2] keys
 
These keys assign are used to assign the signal from 
the [INPUT 1] and [INPUT 2] jacks to tracks. The 
[INPUT 1] jack corresponds to the TRACK ASSIGN [1] 
key, and the [INPUT 2] jack corresponds to the [2] key. 
When you press one of the TRACK ASSIGN keys, that 
key will light. Next, press the [PAN] knob correspond-
ing to the destination track. Both the REC SELECT 
LED and TRACK ASSIGN keys will light, indicating 
the input jack is assigned to that track.
 
TUNER
 
To access the Tuner mode, press the TRACK ASSIGN 
[1], [2] keys simultaneously. The tuner function lets 
you tune an external instrument. Since the effects are 
bypassed in Tuner mode, this provides a way for you 
to compare the sound with the effects on or bypassed.
 
The Tuner function will not operate during playback or dur-
ing record-standby.
 
5. [PRE/FAVE] (favorite) knob
 
Turn this knob to select the effect you want to use.
You can register your eleven favorite effects to this 
knob, and select them simply by turning the knob. 
When the D4 is shipped from the factory, the eleven 
effects printed on the panel are the effects assigned to 
this knob. To assign your own favorites, refer to “Step 
7. Using effects” in the Operation section.
