Top Panel Introduction; Connections; Mod Wh Cv; Osc Cv (Cv In) - Behringer Pro-1 Operation Manual

AP099 Revision 1.01 CM100B
Top Panel
Introduction
This section describes all connections which may be made via the top panel jacks. This section
is the major difference from the original Pro-One, and consists of 15 jack sockets at the top of
the front panel.
On the Pro-One these were Audio out / Audio in / Filter CV IN / Gate Out / CV Out / Gate
Clock In / CV IN. These designations are shown in brackets where they are common with the
Pro-1.
The functions as either input or output are shown in with < or > respectively.
All jacks accept a
standard 3.5mm
mono jack plug
The original Pro-One
had a slightly
different layout, with
some of these
connections on the rear panel and being 6.35mm sockets.
These connections can be used to make alternative connections within the synthesiser, or to
connect other synthesiser units or modules external to the Pro-1.

Connections

MOD WH CV <
Input for Mod wheel CV.
OSC CV (CV In) <
For control of the oscillators and filter at a scale of 1V/octave. Similarly to the FILTER CV IN
jack, when connected, CV IN overrides the normal KYBD CV, but may still be switched by the
OSC B KYBD switch and attenuated by the FILTER KEYBOARD AMOUNT knob. (For the
FILTER, FILTER CV IN overrides CV IN.)
If sound disappears when you connect to this input, you may be driving the oscillators into
the super audio range. Reducing the external CV will return the oscillator frequencies to the
range of human hearing.
GATE/CLK (Gate Clock In) <
External Gate or clock input.Once this digital input is enabled by selecting the REPEAT/EXT
MODE, it provides for envelope gating, or sequencer or arpeggiator clocking by an external
(+5V nominal) pulse.
