The API ASM164 is a 16-channel analog summing mixer that brings the company's legendary analog summing performance to your professional studio in a convenient 19" rackmount format. You'll experience the renowned API sound through its proprietary 2510 input and 2520 output op-amps that deliver a transparent signal path from inputs to outputs. With comprehensive rear panel connections offering balanced inputs/outputs and DB-25 connectors, the ASM164 seamlessly integrates into your existing studio setup. Flexible routing lets you assign each channel to the two stereo program busses (Mix-A and Mix-B) for versatile summing workflows.

The API ASM164 gives you precise level control with 31-detented steps and continuously variable panning with center detent. Comprehensive metering with 4-segment LED meters on each channel and analog VU meters on the main outputs ensures precise level monitoring. Backed by API's reputation for rugged, studio-grade construction and an external power supply, the ASM164 brings the iconic analog summing sound to your professional productions in a space-efficient package.
