Description
Audison SPM4 - 4 CHANNEL STEREO PASSIVE MIXERSPM4 provides the ability to mix the midrange and tweeter channels coming from an amplifier and supply one single mid high channel. The Ch1(L R) channels feature two inputs, one features an inverting input compared to Ch2 (L R) channels; the mixing process often gives better results when one of the two channels undergoes a 180 phase shift. SPM4 is especially recommended for extending the number of inputs of Audison digital processors or amplifiers
SPM4 provides the ability to mix the midrange and tweeter channels coming from an amplifier and supply one single mid-high channel. The Ch1(L/R) channels feature two inputs, one features an inverting input compared to Ch2 (L/R) channels; the mixing process often gives better results when one of the two channels undergoes a 180° phase shift. SPM4 is especially recommended for extending the number of inputs of Audison digital processors or amplifiers with built-in DSP because they feature a De-equalizer (De-Eq). In this case, any possible non-linear acoustic emissions due to the mixing of the pre-existing filtered channels are duly compensated for.
Stereo passive mixer (unpowered) featuring 4 input channels and 2
output channels, designed for active OEM multi-way systems where
each speaker is powered by one specific amplified channel. SPM4
mixes audio through 4 audio transformers specifically developed to
achieve very low distortion and highly linear acoustic response.
