y

 Pickup Blend Control (PICKUP BLEND)

Controls the volume balance between the two built-in pickups. 
The line out jack is compatible with a standard ¼” phone plug. 
Rotate the knob fully to the right [BODY] to produce the signal 
from the pickup underneath the bridge, which reproduces the rich 
tone produced by the instrument’s body. Rotate the knob fully to the left [BRIDGE] to produce 
the signal from the pickup in the bridge, which reproduces bow articulation and quicker re-
sponse. Set the dial to its center position to produce a balanced output of the two pickups.

*  The volume control is not located on the instrument itself, use the volume control on the control 

box to adjust the volume.

u

 Line Out Volume Control (VOLUME)

Adjusts the volume level of the signal delivered from 
the LINE OUT and BALANCED OUT jacks. (It does 
not effect the volume of the Phones jack.) 

i

 Treble Control (TREBLE)

Adjusts the treble or high range frequencies. (Effects 
all output) 

o

 Bass Control (BASS)

Adjusts the bass or low range frequencies. (Effects 
all output) 

!0

 Phones Volume (see diagram on page 7)

Adjusts the volume level of the Phones jack signal. (This volume can be set regardless of 
the main volume control setting.) 

*  If the electric output sound is distorted, lower the VOLUME and other such controls to a suitable level.

!1

 Ground Lift Switch (GROUND LIFT GND/LIFT)

Separates the ground between the instrument and external device when connecting the in-
strument to an external device via the BALANCED OUT XLR connector. The [GND] setting 
is used under normal circumstances. If you experience noise due to a ground loop, move 
the switch to the [LIFT] position to separate the ground between the instrument and exter-
nal device. This is one method that can be used to suppress noise. 

*  When the switch is set to the [LIFT] position, the instrument will not operate with phantom power 

(Refer to page 11). Use batteries or a power adaptor.

!2

 Balanced Out Pad Switch (BALANCED OUT PAD -26dB/OFF)

Attenuates the signal from the BALANCED OUT jack by 26dB.
Setting this switch to the [-26dB] position when connecting the instrument to a small mix-
ing console or other device that only has balanced XLR mic level inputs makes its output 
compatible with a mic level input.
To connect the instrument to a line level balanced input on an external device, set the switch 
to the [OFF] position to send the same level signal as that of the unbalanced LINE OUT.
