The Grendel DC-2 Drone Commander 2, introduced in 2021, represents the Main + Expander from our earlier Grendel DC-2e system fused together as a single eurorack module of 35HP width. DC-2’s front panel features a low-glare brushed aluminum finish, anodized, in both silver (natural) and black. This module requires a rear clearance depth of 72 mm behind the rails in your euro case. The DC power requirement is 120 mA (+12 V), 2.5 mA (-12 V).
Almost all of the DC-2 circuitry is exactly as in the DC-2e, with minor updates. Notably, the v/oct inputs have been re-organized. DC-2 has two 1V/oct inputs, and a 15v/oct input suitable for pitch bender or vibrato modulation — all three v/oct inputs affect both VCO 1 and 2 simultaneously. This differs from the DC-2e, which has separate 1v/oct inputs for each oscillator, plus one 1v/oct input that affects both.
Another noteworthy update to the DC-2 is an increase in dynamic range, less noise, and hotter audio outputs at both the ¼” and 3.5mm output jacks.
The published user manual for the DC-2e also applies to DC-2, except for whats mentioned above!
Drone Commander 2 is an all-analog synth voice module. It incorporates two VCOs, two VCFs, two synchronized sawtooth LFOs, a special dual sinewave LFO dedicated to VCO PWM, an attack-release envelope generator that controls low pass gate, and a triggered variable shape ‘Slide’ LFO. There are 12 control voltage I/O patch points, 4 clock and gate I/Os, 2 audio outputs, and 1 audio input. All 12 solid metal knobs double as push-pull switches for secondary functions such as signal routing, envelope gate on/off, and filter mode.

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
