Instrument Input; Output Level Control; Balanced Output - PulpLogic Entry Point User Manual

1. Instrument Input

1/4" phone jack input for connection to both passive and
active instruments.
2. Active/Passive Selector Switch
Selects the amount of gain required to bring your instrument's
output up to a line level signal. For passive instruments with
standard high impedance pickups the switch should be set to
PASSIVE for best results. When using instruments with on-
board active electronics or when feeding the Entry Point from
the output of an external preamplifier, the switch should be
set in active mode. Some instruments with active pickups
(like EMG) produce relatively low output signals and may
work best in passive mode. Since every instrument is
different experimentation is encouraged.

3. Output Level Control

Sets the output level for the 3.5mm SIG jack. The required
output level is dependent on the next module in the
processing chain. Experiment with driving filters and other
modules with different amounts of gain to broaden your
sound palette. Once you find the sweet-spot for a particular
module, note the LED metering level for repeatability.
4. Output Level Metering
The LED output metering provides a visual feedback for the proper level settings. The meter is particularly
valuable when playing live as it allows you to quickly setup your system based on predetermined levels.
5. Fundamental Tracking
The TRACK control is used to set the bias for the fundamental extractor. In the counterclockwise position the
extractor is at it's most sensitive setting. In this position the extractor may be unreliable when tracking low
frequency notes and open strings. This will be evident by the note jumping between the fundamental and an
octave above the fundamental. As the control is rotated clockwise, tracking will improve but the sustain will
be shortened.
6. Envelope Threshold
The envelope threshold control THRESH is used to set the minimum signal necessary before an envelope is
created. Once the input signal crosses the set threshold level, an envelope will be present on the ENV+ and
ENV- jacks. The amplitude of the envelope will be the amount of signal over threshold multiplied by the ratio.
The blue led illuminates when threshold has been exceeded.
7. Envelope Ratio
The ratio control sets the gain for the envelope follower. Large envelope ratios allow for the generation of
envelopes that span the full control range on input signals that just barley exceed the threshold.
8. Output Group
3.5mm output jacks for interfacing with Eurorack modules. The SIG jack delivers a clean Eurorack level
representation of your instrument's output. The SQR jack is the square wave output of the fundamental
extractor. The ENV+ and ENV- jacks output the rising and falling envelope control voltages. The rising envelope
is 0V to 5V and the falling envelope is 5V to 0V or 0V to -5V.

9. Balanced Output

This output provides a line level balanced copy of the input signal. The jack is TRS balanced with the tip
connected to the in phase signal and the ring to the -180° signal. It is safe to use a standard TS instrument
cable if an un-balanced output is needed.
