The Northern Light Modular Electric Dompteur – Model hED is a swarm LFO comprising eight linked true-zero LFOs with phase offset and spread.

The Northern Light Modular Electric Dompteur - Model hED offers eight different waveforms for the LFO including sine, falling and rising ramps, square, pulse and random. The master frequency can then be offset in phase or spread for all eight LFOs. In phase mode each step can be offset up to 180 degrees. In spread mode, the offset is based on subharmonics of the master frequency.

The frequency of the LFO ranges from 0 to 300Hz. A Clock input also accepts MIDI clock sync. When a connection is made to the clock, the LFO becomes a multiplier.

The h-Series is half the height of a 1U 200 Series module and requires an h bracket to be mounted in a 1U space. Two h modules can be mounted in a 1U space.
