API ASM164 Analog Summing Mixer Review - TapeOp Magazine | Tape Op Magazine

tapeop.com

API's ASM164 summing mixer delivers the brand's signature warmth and musicality in a compact rack unit. Its 2520 op-amp and transformer output design enriches the sound, pushing elements forward in the mix with notable midrange presence. The dual stereo bus architecture is perfect for parallel processing, enhancing versatility for various workflows. While the ASM164 excels in adding character, it might not suit those seeking transparency, though bypassing the output stage offers a neutral option. At $3195, it's a solid choice for studios craving analog warmth and flexibility, embodying the classic API sound.
