Diamond Audio’s NEO DSP amplifier family was announced on August 14, 2026. This feature looks at one practical detail of the NEO12004DSP: its amplifier-channel count and DSP-channel count are different.
Four powered channels, six processed channels
Diamond lists four internal amplifier channels and two RCA outputs, with six-channel DSP processing. Its specifications rate the amplifier at 150 watts per channel into 4 ohms or 300 watts per channel into 2 ohms. Bridged output is listed as two channels at 600 watts into 4 ohms.
The onboard tuning includes 31-band parametric equalization, crossovers, time delay and channel linking. The two RCA outputs provide expansion connections; they are not two additional amplified speaker outputs.
Make the plan easy to follow
Sketch each speaker and the amplifier channel intended to power it before shopping. Keep signal connections on a separate line. That simple drawing helps prevent a six-channel processing label from becoming a six-speaker-power assumption.
