PRO series channel constant voltage/constant resistance multi-purpose DSP digital amplifier

PROThe series amplifier is a flexible, stable and reliable 4-channel DSP power amplifier designed based on Infineon Drive Core technology chip. It can provide power for 8ohm/16ohm low impedance speakers and 70Vrms/100Vrms high impedance distributed lines without the need for output boost transformers, and can achieve higher audio quality in high impedance distributed audio applications. The simple front panel functions and rear panel wiring ports make the work of system technicians easier and faster. The installation height is only 1U (44mm), which is very suitable for multi area installation projects of command vehicle sound reinforcement systems and small and medium-sized venues.

First class quality, simple and easy to use

* Concise front panel features, LCD display, and rear panel wiring ports

*S-ΔmodulationSwitching mode output stage achieves high-efficiency power amplification and high-quality sound

* Onboard high-resolution DSP (with 24 bit 192KHZ A/D converter and 32-bit 192KHZ D/A converter)

* LCDThe control area is used to adjust the gain and mute of the power amplifier, configure the power amplifier, set and cancel DSP presets, so that the power amplifier can be flexibly configured for different applications

* Using the USB interface on the front panel, you can adjust the preset in the computer specific control program, transfer it to the amplifier DSP, or transfer the preset from the amplifier DSP to the computer specific control program

* The built-in DSP functions include: channel mute, channel routing, volume control, constant voltage/constant resistance output mode switching, input/output synchronous coupling, polarity reversal, 7-segment parametric equalizer, high-low pass filter, digital voltage limiter, 250mS digital delay, etc;

Strong practicality and diverse functions

* Can directly drive fixed resistance loads or 70V/100V high resistance distributed lines, suitable for any mixed fixed resistance/constant voltage configuration

* Each channel comes with high and low impedance settings

Highly reliable power supply design

* 176V~264VAC power input range, dedicated power filter, with ripple elimination network function.
