The ADSP-Z16 IV-12A is an integrated 16-channel DSP and 12-channel amplifier delivering 12 × 120 W at 2 Ω or 12 × 80 W at 4 Ω. Built on the same CS47048 32-bit/192 kHz DSP platform as the rest of the DSP-IV series, it supports 12 channels of speaker-level input (2–20 V) with auto-on, 8-channel RCA input, and 4-channel RCA output, along with coaxial and optical digital inputs. The optional HD-BT module adds aptX HD Bluetooth streaming.
