1, 2,
GAIN
2/1: Jacks 1 and 2 are audio inputs for Micro-
phone or Line signals (a musical instrument, cassette re-
corder, CD player or microphone). For mono connec-
tions use the IN 1 jack. The volume of the MIC/LINE
signals fed into the IN 1 and 2 jacks can be regulated
with the front panel MIC/LINE control. The gain 2/1 twin
knob controls the volume of the signal fed into the Inputs.
Gain 1 (the smallest central knob) regulates IN 1, gain 2
(the larger outer knob) regulates IN 2. All to the left (min-
imum) corresponds to the LINE impedance (stereo de-
vices and musical instruments). All to the right (maxi-
mum) corresponds to the MIC impedance (microphones).
The optional A/V board is required for most external
processing applications.
6. OUTPUT
L
EFT
,
RIGHT
, 1, 2: Stereo Left-Right Outputs and auxiliary
1, 2 outputs to listen to the WK4 sound through an exter-
nal device such as a mixer or audio amplifier. For Mono
reproduction, use either the RIGHT or LEFT jack. The
auxiliary outputs emit “dry” sounds (i.e. with no effects).
7. VIDEO (AUDIO/VIDEO INTERFACE)
RGB. Video output in RGB/Composite Video standard.
SVHS. Video output in SVHS/Composite Video stand-
ard.
Both outputs are operational only with the optional Au-
dio/Video Interface.
Models not fitted with the A/V Interface leave the factory
with an adhesive applied below these outputs saying “NO
VIDEO INTERFACE INSTALLED”.
8. MAIN SOCKET
Insert the supplied power cord into this socket.
1. PEDALS

AMPER
, 1, 2, V
OLUME
: Three programmable jacks for con-
tinuous control pedals or switch action pedals (Damper,
1, 2) and a Volume jack for a standard Volume pedal.
The footswitch polarity of the switch action pedals can
also be reversed.
2. PEDALB.
P
EDALBOARD
: Connector for a pedalboard (optional). En-
abling the pedalboard disables the computer port auto-
matically. Pedalboard settings are enabled in Edit Gen-
eral.
3. COMPUTER
Computer port: Serial port which permits WK4 to be con-
nected directly to a computer (Apple Macintosh or IBM
PC and compatibles.) Data interchange between WK4
and PC or Mac requires appropriate setting in Edit Gen-
eral.

A/B: Two series of
independent connectors (A and B) used to control other
MIDI instruments or to communicate with a Computer.
IN: receives data from another instrument. OUT: trans-
mits data to another instrument. THRU: retransmits data
received at MIDI IN.
When using WK4 on its own, these jacks are not required
to be connected.
