E490

The E490 is based on the 5U MOTM-490, updated for Eurorack.

The E490 Ladder VCF is a 10HP, Moog 904A 4-pole lowpass filter using modern transistors, but exactly matching the characteristics of the original. Using these new, matched dual and quad transistors allows the E490 to have lower noise and better tracking than the 904A without changing all the ‘quirks' in the sound.

Panels are available in black or silver, at the same price.

The 904A has several distinct characteristics which the E490 duplicates:

• Low frequency self-resonance begins at 72Hz
• There is a mid-frequency ‘dip and bump' due to phase shifts
• The output amplitude drops as resonance increases
• The resonance drops as the amplitude increases
• The filter will ‘track sharp' past 400Hz (it tracks OK 100 – 400Hz)
• If you push the RANGE trimmer to max, it can oscillate to over 20KHz

The MSRP is $249. This production run is limited to 220pcs, due to parts constraints.

Analogue Haven will be the exclusive dealer for the E490 for the near future. This may change at a later date.
