SE-02 EXT BOX
MULTI-FUNCTION EXTERNAL CONTROLLER

OVERVIEW

Designed specifically for the SE-02, the EXT Box is a multi-function external controller, offering high CV resolution filter frequency control with a full-sized knob. It also features an 1/8" to 1/4" connection converter for External Input and Audio Out. A drive-adjustable hi-pass filter with attenuation, rich overdrive and extremely potent boost, add rich character and depth, while expanded external input control, expressive gate triggering for external signal/sample manipulation, expand and inspire; let it breathe new life and fire into your beloved (and usefully compact) SE-02.

And what the Ext Box does for the SE-02, it can for many desktop synths and modules which offer some combination of External Input control, CV, Gate, and VCF CV connections; we recommend our Boomstar and Boomstar Modular Eurorack modules—especially the Tonestar.

SPECIFICATIONS

• Variable high-pass filter with drive control, for severe distortion and gain boost with on/off switch

• Interface to 1/4" connections: external input/audio output

• External Input 1/8" and 1/4" multed

• Audio Output 1/8" and 1/4" multed

• Secondary VCF CV input

• Filter CV source switch: knob or secondary source selection—such as your modular

• 3 Gate options: fixed gate switch, momentary gate switch (transformer), external gate input

• Large filter control knob for smooth or sharp, highly articulated sweeps

• Back panel 1/8"-1/4" connections: 1/8” and 1/4" inputs; 1/8” and 1/4” outputs

• Din interconnect: Output, Ext Input, VCF CV, Gate (cable included)

• True bypass

• Eurorack voltage compatible

• Interfaces with other desktop and modular synths

• 12v 3 prong low profile power adapter: one socket space for the US supply; the EU/UK supply is slightly larger and heavier

• Roland® style metal sides option
