Sustain Pedal MARANTZ Kurzweil KP-2 — single-foot switch for digital pianos and keyboards

The Sustain Pedal MARANTZ Kurzweil KP-2 is a single-foot switch designed to provide standard on/off sustain control for digital pianos, stage keyboards and MIDI controllers that accept a 1/4" (6.35 mm) pedal input. The unit connects with a standard TS instrument cable and translates a simple foot press into sustained note behavior, allowing players to hold tones and chords without maintaining finger pressure. Its compact form-factor and straightforward wiring make it suitable for practice, live performance and studio use.

Advantages

The KP-2 delivers reliable mechanical action and consistent on/off switching compatible with most keyboards and controllers. Its durable housing and non-slip base improve stability during use, while the standardized jack ensures broad compatibility. The pedal’s simple single-switch design minimizes latency and possible configuration issues compared with multifunction pedals, providing a predictable sustain response for players of all levels.

Suitable for

• Digital pianos and stage keyboards with a 1/4" pedal input
• MIDI controllers requiring a momentary sustain switch
• Home practice where hands-free sustain is needed
• Live gigs and stage setups with compact pedal requirements
• Studio sessions for recording sustained notes and passages

Key specifications

• Connection: 1/4" (6.35 mm) TS jack
• Operation: mechanical momentary on/off switch (sustain)
• Compatibility: standard passive sustain input on keyboards and controllers
• Housing: compact, low-profile pedal with non-slip base
• Cable: external connection via instrument cable (cable not necessarily included)

How to use

Connect the sustain pedal to the instrument’s pedal input using a 1/4" (6.35 mm) TS cable. Place the pedal on a stable surface in front of the keyboard at a comfortable distance. Press and hold the pedal with your foot while playing to sustain notes or chords; release to stop sustaining. If the instrument has a polarity or sustain switch setting, verify the correct polarity in the keyboard’s settings to ensure proper on/off behavior.

Usage recommendations

For consistent performance, use a good-quality 1/4" TS cable and position the pedal on a flat surface. Check your instrument’s pedal polarity option if sustain operates reversed; many keyboards allow switching polarity in the settings. Avoid exposing the pedal to moisture and store it in a dry place when not in use.
