Description

The Citronic D4350 is a quad digital power amplifier built into a lightweight 1U rack-mountable case. It delivers 350Wrms across each of its four independent speaker outputs, drawing on a switch-mode power section and a class-D amplifier circuit. This design keeps the unit energy-efficient and provides accurate power-on-demand, so the amplifier draws only what the load calls for. Proprietary cool guide technology handles temperature management to keep operation stable over long sessions.

Each pair of output channels can be switched independently to run in parallel or bridged mono, which lets you set the D4350 up as a quad, stereo or 2.1 system to suit the job. Channel A carries a switchable 120Hz low-pass filter (LPF) for use with subwoofers, while channels C and D share a switchable stereo pair of 120Hz high-pass filters (HPF). Those crossovers focus power in full-range cabinets running as mid-tops alongside subs, so you can build a working system without a separate processor.

The signal path is fully balanced, and inputs are made through four XLR female connectors with output on four SPK connectors. Full audio and power protection is included, along with a peak limiter to guard both the amplifier and the connected speakers. For permanent or mobile installations, the D-series gives audio designers and sound engineers a flexible problem solver in a single rack space. Power comes from a 220-240Vac 50/60Hz IEC supply, and input sensitivity is set at 0dB = 0.775Vrms.
