The SPM-1 3U half-rack powered speaker monitor offers "Ultra Near Field" monitoring, which focuses sound directly to the operators ears making channels distinguishable, reducing acoustic crossover, and keeping noise to a minimum.

The unit monitors analog audio signals and fits into a standard 3U half-rack frame.

Because it is fully magnetically shielded, it can be mounted next to a vector scope, waveform or video monitor without causing interference.

The SPM-1 accepts analog audio signals on four XLR connectors.

The unit also features analog loop-through output connectors, independent lighted source select buttons with summing feature, lighted mute button, volume control, and headphone output.
