The HDA-130 is the smallest amplifier in URC's HDA distributed audio family: one stereo zone at 30 watts per channel into 8 ohms, stable down to 4 ohms, in a chassis small enough to tuck behind a display or above a ceiling. A separate left and right preamp output lets you add a powered subwoofer to the same zone. It is not just a local amp, though, since whatever is plugged into its inputs can be streamed across the HDA network to other zones at 96 kHz and 24 bits.

Inputs are a 3.5mm analog jack and a TOSLink optical digital input carrying PCM. Per zone processing includes high pass and low pass filters and a full 5 band parametric EQ, plus ducking so paging or a microphone automatically pulls the music down. Up to ten WAV files can be stored in the chassis for doorbell chimes and trigger alerts. The unit runs on 100 to 240 volts AC or PoE++ and connects over gigabit Ethernet. A system processor and programming by an authorized URC Total Control dealer are required, and an HDA-SW5 AVB switch is needed once more than one HDA product is on the network.
