Ahead of Superbooth 2018, Moon Modular’s Gert Jalass let us know that they are now shipping the M504 Voltage-Controlled Low Pass Filter.

The M504 is a traditional ladder-type low pass filter, with switchable 6/12/18/24 dB/oct slope and voltage-controllable cutoff frequency and regeneration.

A three-way slope toggle switch lets you select between 12 db/oct, 6 or 18 dB/oct (switchable via jumper on the rear side) and 24 dB/oct. An additional jumper on the rear lets you choose between the traditional behavior of the classic Moog ladder filter design, and an update that compensates for volume-loss at high resonance levels.

The module is calibrated for ±15 volts and includes both DotCom and Cotk/Moon style power connectors.

Pricing and Availability

The M504 Voltage-Controlled Low Pass Filter is available now for 279 EUR (incl. German VAT of 19%).
