The ADSP-Z12 IV-10A is an integrated 12-channel DSP and 10-channel amplifier delivering 10 × 120 W at 2 Ω or 10 × 80 W at 4 Ω. The CS47048 32-bit/192 kHz DSP core provides 31-band graphic/parametric equalization, four crossover filter types, and time alignment across 12 processing channels. Coaxial and optical digital inputs, 8-channel speaker-level inputs with auto-on, and a port for the optional HD-BT module round out the connectivity.
