Fig. 5 Patch Bay Features
The patch bay consists of fourteen 1
/
4” jack sockets which you can use to receive and send various control
voltage signals. If an arrow is pointing towards the jack socket it shows you that this is an output, if the
arrow is pointing away from the jack socket it is an input.
Let's start from left to right in the upper row.
CLOCK
(analog clock output)
This is the main clock output of the RH301. It sends a 50% duty cycle square wave signal. The
tempo is dependent on various settings explained above. The CLOCK output is twofold and
both outputs are buffered.
DIVISION
(analog clock output)
This is the division output, sending a 50% duty cycle square wave signal depending on the
setting of the rotary DIVISION switch. The DIVISION output is twofold and both outputs are
buffered.
EXT. CLOCK
(analog clock input)
This CV input accepts rising edge driven analog clock signals. Every time a signal rises from
0V – 3V the pedal counts one beat.
LFO SPEED
(CV input)
The LFO SPEED CV input controls the speed of the LFO, therefore plugging a CV signal into
this jack will change the speed of the LFO. When you insert a control voltage into this input
the RATE knob determines the offset voltage (see Control Voltage Theory section). (Usable
range from 0 – 5V).
LFO RESET
(CV input)
The LFO RESET input can be used the externally reset the LFO to bar 1 at any time. The
input reacts to any rising edge trigger that changes from 0V to 3V.
Left to right, lower patch bay row:
ENV
(CV output)
The ENV CV output holds the signal of the envelope generator. Signal ranges from 0V – 7.6V.
ENV INV
(CV output)
The ENV INV CV output is the inverted envelope output. Signal ranges from 7.6V – 0V.
LFO
(CV output)
This is the main LFO output of the pedal. The LFO can be shaped and set up in the LFO
section of the pedal. Signal ranges from 0 – 7.6V.
