Behringer 140 DUAL ENVELOPE/ LFO User manual

Quick Start Guide
140 DUAL ENVELOPE/ LFO
Legendary Analog Dual Envelope/LFO
Module for Eurorack
Controls
(1) MANUAL GATE – Press and hold to start the
envelope cycle.
(2) EXT GATE – Connect a gate signal to control the
envelope cycle.
(3) ATTACK TIME – Adjusts the rate at which the envelope
reaches its peak voltage.
(4) DECAY TIME – Adjusts the rate at which the envelope
decays from its peak level to its designated sustain level.
(5) SUSTAIN LEVEL – Controls the level at which the
envelope remains after its peak but before release,
sustaining as long as the input signal is present or the
manual gate switch is held down.
(6) RELEASE TIME – Controls how quickly the envelope
falls after the input signal stops or the manual gate
switch is released.
(7) ENV OUTPUTS – Send up to 2 positive waveforms
and a negative waveform to other modules via these
output connectors.
(8) FREQ RANGE – Sets the oscillating frequency range of the
LFO in 3 steps.
(9) FREQ – Manually sets the oscillating frequency of the LFO.
(10) DELAY – Sets the time from when a trigger signal is
received until the LFO begins operating again.
(11) FREQ CV IN – Accepts voltage for controlling the LFO
frequency with an external source.
(12) TRIGGER - Connect a trigger signal to turn the LFO
o until the end of the trigger cycle. This works along
with the Delay slider, and the LFO recovery takes about
20 seconds. The rear panel features a jumper that can be
removed if you don’t want the LFO to be re-triggered.
(13) OUTPUT LEVEL – Selects between standard or 1/10th
output level for the LFO OUT jacks.
(14) WAVEFORM – Select between sine, triangle,
pulse, sawtooth or reverse sawtooth for the LFO
waveform output.
(15) LFO OUT – Sends the LFO output to other modules.
The upper jack is non-inverting and the lower jacks
is inverting.
Power Connection
The 140 comes with the required power cable for connecting
to a standard Eurorack power supply system. Follow these
steps to connect power to the module. It is easier to make
these connections before the module has been mounted into
a rack case.
1. Turn the power supply or rack case power o and
disconnect the power cable.
2. Insert the 16-pin connector on the power cable into the
socket on the power supply or rack case. The connector has
a tab that will align with the gap in the socket, so it cannot
be inserted incorrectly. If the power supply does not have
a keyed socket, be sure to orient pin 1 (-12 V) with the red
stripe on the cable.
3. Insert the 10-pin connector into the socket on the back of
the module. The connector has a tab that will align with the
socket for correct orientation.
4. After both ends of the power cable have been securely
attached, you may mount the module in a case and turn on
the power supply.

Installation
The necessary screws are included with the module for mounting
in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of xed holes
spaced 2 HP apart along the length of the case, or a track that
allows individual threaded plates to slide along the length
of the case. The free-moving threaded plates allow precise
positioning of the module, but each plate should be positioned in
the approximate relation to the mounting holes in your module
before attaching the screws.
Hold the module against the Eurorack rails so that each of the
mounting holes are aligned with a threaded rail or threaded
plate. Attach the screws part way to start, which will allow
small adjustments to the positioning while you get them all
aligned. After the nal position has been established, tighten the
screws down.
