Audison SPM4 Passive stereo mixer (unpowered) with 4 input channels and 2 output channels

Device designed for active multiway OEM systems where each speaker is powered by a specific amplified channel. The Audison SPM 4 performs mixing through 4 audio transformers specifically designed to have very low distortion and high linearity. SPM4 allows you to mix the midrange and tweeter channels coming from the amplifier and provide a single mid-high channel.

The Ch1(L/R) channels have two inputs, one of which is inverting with respect to the Ch2 (L/R) channels; frequently mixing gives better results by phase-shifting one of the two channels by 180°. SPM4 is particularly suitable for extending the number of inputs of Audison digital processors or amplifiers with DSP as they are equipped with de-equalizer (Re-Eq). In this case any non-linearities due to the mixing of pre-existing filtered channels are duly compensated.
