A quick glance at the Denon user manual suggests that it has analogue RCA sub outputs.

The D2500 requires a digital SPDIF PCM feed and needs to be paired with a Meridian DSP speaker as it is not capable of being a "Master" (i.e. switching itself on and off, etc.) on its own.

See the D2500 user manual
