Black Lion Audio PM-8 MKII Summing Mixer (Demo Deal)

Summing in the analog domain is widely regarded as superior to mixing "in the box."  The DSP required to sum individual channels into a stereo pair is prone to clock-based errors and mathematically unrelated signal artifacts, something avoided entirely by mixing down in the analog domain.  While issues of channel cross-talk, thermal noise and distortion are problems faced in the analog world, these artifacts are considered more euphonic than those created in the digital domain.

Introducing the Black Lion Audio PM-8 summing mixer.  It features eight channels of transformer-coupled inputs and three separate master outputs: a passive output, a transformerless output, and a transformer coupled output.  It has mute, volume and pan capability on each channel, plus a DB25 connection to link a second summing box.  Huge 3/4 Watt bus resistors provide isolation between channels while minimizing the thermal noise typically found in a small format console bus.  Grain oriented silicon steel input and output transformers lend a rich coloration to the sound by adding just a touch of low-order distortion below 250Hz.  

Updated features in MKII version:

• Separate monitor outs for each output pair
• New link feature allows connection of multiple PM-8 MKII units using Tascam-standard DB25 connection
• Separate monitor volume control
• Swappable input and output transformers
• New anodized faceplate
• Updated retro knobs
