The API ASM164<\/strong> is a professional-grade 16-channel analog summing mixer<\/strong> that brings the classic API console sound to a compact, rackmount format. Inspired by the summing section of API’s renowned THE BOX\u00ae console<\/strong>, the ASM164 is designed to deliver world-class summing performance for home studios, professional project rooms, and commercial production environments<\/strong>.<\/p>\n Built on API\u2019s legendary discrete analog architecture, the ASM164 features proprietary API 2510 input op amps<\/strong>, 2520 output op amps<\/strong>, and transformer-balanced outputs<\/strong>, ensuring your mixes benefit from the punch, warmth, and clarity that define the API sound. With 16 balanced line-level inputs via DB-25 connectors<\/strong>, the ASM164 offers a versatile front-end for hybrid mixing workflows.<\/p>\n Each of the 16 channels can be assigned to Mix-A, Mix-B, or both<\/strong>, allowing flexible routing and parallel processing. Every channel includes a continuously variable pan control<\/strong> (with center detent), 31-step detented level control<\/strong>, and insert send\/return<\/strong> for integrating outboard gear. The global 0dB bypass<\/strong> enables a direct unity-gain mix for reference or recall-friendly setups.<\/p>\n Additional features include a balanced stereo external input<\/strong> assignable to either mix bus, 4-segment LED meters<\/strong> for each channel, and high-quality VU metering on the stereo outputs<\/strong>. The ASM164 offers comprehensive rear-panel connectivity and is powered by an external supply for reduced noise and increased reliability.<\/p>\n The API ASM164<\/strong> offers the unmistakable API summing sound in a compact and efficient format, making it an ideal addition to any hybrid studio setup that values analog warmth and clarity in the final mix.<\/p>","protected":false},"excerpt":{"rendered":" API ASM164 16-Channel Analog Summing Mixer The API ASM164 is a professional-grade 16-channel analog summing mixer that brings the classic API console sound to a compact, rackmount format.
