OVERVIEW

The UNiKA DSP 4000 power amplifier is professionally designed for both installed sound application and portable PA. The DSP 4000 includes DSP Digital Signal Processor which is available to use RS-485 interface to connect with computer for operation. This unit is rugged and offer the best value at an affordable price.

The DSP 4000 power amplifier is setup with a powerful, high-current toroidal transformer, it provides stereo mode and bridged mono mode in variable ways of using the unit. The DSP 4000 power amplifier has been thoroughly tested before shipment and designed to mount into a standard 19" rack.

DESCRIPTION

The DSP 4000 is equipped with selectable input and output terminals that make them suitable for professional sound application: XLR and 1/4” TRS input terminals with 5-way binding post and Speakon output terminals, which accept balanced and unbalanced connections. Use these connections to connect the output signals from a mixer, a crossover or an EQ to your DSP 4000 amplifier. And there are extra XLR output connectors for signals easily passing through to multi-amps setups. The 5-way binding post and Speakon output connections for dual channels or bridged mono channel. 

Protection circuits include short circuit protection and detent gain controls. The circuit breaker is designed to protect the amplifier and your speakers in the event of an AC overload. Detent gain controls for easily repeatable settings.  

Built-in limiter allows signals below a specified input power to pass unaffected while attenuating the peaks of stronger signals that exceed this input power. The input sensitivity is fixed at 1V.

Indicators clearly showed the status of the protection systems and other parameters: each channel is designed with separate PROTECT indicator indicates protection circuit activation; SIGNAL level at -6dB, -3dB, 0dB, LIMIT and CLIP LED indicators. Continuously dual 2-speed fans efficiently prevent overheating and maintain high stability.

The DSP 4000 is designed as a digital power amplifier, it contains DSP (Digital Signal Processor) to control the related functions, such as EQ, LPF (Low Pass Filter), HPF (High Pass Filter), Limiter, Delay and digital signal input, via the front panel LCD display, and can be adjusted when connect it to computer with its exclusive control software.
