An external input module that brings microphones, instruments, and line-level sources into a Eurorack system via a transformer/opamp mic preamp and a FET instrument/line preamp, with phantom power, pad, HPF, envelope follower, and comparator.894

Capabilities 4

Comparatorcomparator
Compares the envelope follower signal against a manually set threshold; when exceeded, a gate signal is output at the Comparator Gate Output.894
Envelope Followerenvelope-follower
Built-in envelope follower with manual attack and release controls generates a unipolar positive envelope output from the input signal, with a comparator threshold-based gate output.894
External Inputexternal-input
Accepts XLR microphone and TS instrument/line level signals, converting them to modular-level signals via its dual-channel preamp.894
Preamplifierpreamplifier
Provides both a transformer/opamp mic preamp (up to 60dB gain) and a FET instrument/line preamp (over 40dB gain), with phantom power, pad, and HPF on each channel.894

Jacks 4 (1 in / 3 out)

NameSignalVoltageDescription
Inputs (1)
XLR/TS InputaudioAccepts either XLR microphone-level or TS instrument/line-level signals for amplification to modular levels.894
Outputs (3)
Comparator Gate OutputgateOutputs a gate signal whenever the envelope follower exceeds the comparator threshold setting.894
Envelope OutputcvUnipolar positive CV output derived from the envelope follower tracking the input signal amplitude.894
OUTaudioFinal audio output after preamplification and level attenuation.894

Parameters 9

NameTypeRangeBehavior
AttackknobApplies slew to the attack time of the generated envelope follower signal.894
Comparator ThresholdknobSets the level of the envelope follower signal at which the comparator triggers a gate output.894
GainknobSets the amount of preamplification applied to the input signal; monitored via the VU meter on the output.894
HPF ToggleswitchA two-position toggle that applies an 80 Hz high-pass filter to the input signal when in the left position, and bypasses the filter when in the right position.894
Input ToggleswitchA two-position toggle selecting XLR microphone-level input in the left position or TS instrument/line-level input in the right position.894
LevelknobAttenuates the final output signal level sent to the OUT jack.894
Pad ToggleswitchA two-position toggle that applies -20 dB attenuation to the microphone input when in the left position, and disables the pad when in the right position.894
Phantom Power ToggleswitchA two-position toggle that enables +48V phantom power to the mic input when in the left position, and disables it when in the right position.894
ReleaseknobApplies slew to the decay/release time of the generated envelope follower signal.894
