Audison SPM 4

4CH Passive Stereo Mixer

 

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. Spm4 Provides The Ability To Mix The Midrange/Woofer And Tweeter Channels Coming From The 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° Dephasing. Spm4 Is Especially Recommended To Extend The Number Of Inputs Of The Audison Digital Processors Or Amplifiers With Built-In Dsp Because They Feature A De-Equalizer (De-Eq). In That Case, Any Possible Non-Linear Acoustic Emissions Due To The Mixing Of The Pre-Existing Filtered Channels Are Duly Compensated.
