Note: When the SW-2 (or any mono foot switch) is plugged in, it will act as a
permanent shut-off switch for the second (stereo) foot switch. Many of the quick steps
for getting around on the DP / 4 (requiring two simultaneous button presses) will not
work properly because the DP / 4 reads the second (stereo) foot switch connection as
constantly engaged. Also, when a mono foot switch is connected and the DP /4 power
is switched on, you will briefly see "Button #15" in the display. This is normal, and
does not indicate a problem.
When the SW-10 is connected
to the FootSwitch jack:
It offers two separately
controllable pedals that can
select presets, bypass effects,
or act as modulation sources
6) Pedal/CV
When the SW-2 is connected
to the FootSwitch jack:
~U~U~U~U~U
Mono
It offers one controllable pedal
that can select presets, bypass
effects, or act as a modulation
source and disables FtSw2
Thisjack is for connecting an optional ENSONIQ Model CVP-1 Control Voltage Foot Pedal,
which is assignable as a modulator to parameters within the DP / 4.
Pedal/CV Specs: 3-conductor (tip
=
control voltage input, ring
=
470 Ohm resistor to +5 volts,
sleeve
=
ground). 2Meg input impedance, DC coupled. Input voltage range
=
a
to 5 volts DC.
For use with an external control voltage, use a 2-conductor cable with the voltage on the tip and
the sleeve grounded.
7) Output Jacks
The four mono output jacks can be configured in numerous ways. Because the DP / 4 offers fully
programmable output control, you can have almost any combination ranging from a single mono
output to four mixed stereo signals.
8) Input Jacks
These four mono input jacks are truly independent inputs and can be used in a 1 source, 2 source,
3 source, or 4 source configuration.
Note: As the labels on the Input and Output jacks indicate, the DP / 4 employs
extensive automatic switching on each stereo pair of inputs and outputs. That is:
• Normally, Inputs 1 and 2, and Inputs 3 and 4 are treated as stereo inputs. However, if
nothing is plugged into 2 or 4, Inputs 1 and 3 will work as mono inputs and will also provide
signal to Inputs 2 and 4 respectively.
• Similarly, Outputs 1 and 2, and Outputs 3 and 4 are normally stereo outputs. If nothing is
plugged into Outputs 2 or 4, however, the stereo signal will be summed to mono and sent to
Outputs 1 and 3 respectively.
• If nothing is plugged into Output 3, the stereo signals from outputs 3 and 4 will be summed
with the stereo signal from outputs 1 and 2 before the automatic switching circuit described
above.
~ Important:
You must use cables with mono 1/4" phone plugs for both the Input and Output
Jacks, in order for the DP / 4 to function properly.
