The Behringer CS100 is a compact analog compressor and sustainer pedal. Behringer describes it as a simple way to improve overall tone, promising "super-smooth compression and endless sustain." The pedal works by compressing louder signals while at the same time boosting lower signals, which RockBoard's PedalPedia says delivers silk-smooth sustain without compromising sound quality.1
If you are new to compressor pedals, the CS100 sits in the entry-level tier of Behringer's range, alongside the Behringer Compressor Sustainer, the Behringer Dynamics Compressor and the larger Behringer CS4001.
Controls
The CS100 keeps things simple with four dedicated knobs for sound shaping:
| Control | What it does |
|---|---|
| Level | Sets the overall output level |
| Tone | Shapes the tonal character |
| Attack | Sets how the front of each note comes through |
| Sustain | Sets how long notes are held |
RockBoard's PedalPedia says these dedicated Level, Tone, Attack and Sustain controls are designed for easy sound shaping.1
Power and bypass
The CS100 runs on a 9V DC supply with center negative polarity and draws 30mA. It also supports a 9V battery, so it can be used without a supply at all. A DC power supply is not included with the pedal.1
The CS100's electronic switching means it is not described as true bypass. RockBoard's PedalPedia states that "a first-class electronic On/Off switch is integrated" for absolutely noise-free operation.1

Questions
Does the Behringer CS100 take a battery?
Yes. The CS100 can run on a 9V battery, or on a 9V DC power supply with a center negative connector. Note that a DC power supply is not included with the pedal, so battery power or a separately purchased supply are the two options.
Does the Behringer CS100 come with a power supply?
No. Behringer's product information states that you can run the CS100 on a 9V battery or a DC power supply, and that the power supply is not included. If you plan to power it from a pedalboard supply, you will need a 9V DC, center negative output rated for at least the pedal's 30mA current draw.
Is the Behringer CS100 analog or digital?
The CS100 is an analog pedal. Its circuit type is listed as analog, meaning the compression and sustain are handled by analog circuitry rather than digital processing.
Is the Behringer CS100 true bypass?
Behringer does not describe the CS100 as true bypass. Instead, the pedal uses what the company calls a first-class electronic On/Off switch, which it says is integrated for absolutely noise-free operation.
What polarity does the Behringer CS100 power supply need?
The CS100 needs a 9V DC supply with center negative polarity, the same convention used by most modern compact pedals. The pedal draws 30mA, so a standard 9V output on a pedalboard power supply should handle it.
