DMP NEW | DIGI-SYS

General Description:

DIGI-SYS Pro Audio Monitoring is a perfect solution for professional audio level monitoring requirements in broadcast stations and production studios. The design of the unit can handle analog stereo signals as well as AES/EBU digital format audio signals with built in high quality D to A converter and associated circuits. All sample rates up to 192 KHz are supported and selected automatically. Digital signals support 16 to 24 Bit resolutions at all sample rates and is again automatically selected.

Built in three way digital crossover network is perfectly matched to the power full drivers. The current unit has predefined curves to cross match the drivers with bass boost support. The colour display with interactive GUI provides all the vital digital format parameters and also acts as a digitally controlled volume control.unit has a dedicated headphone monitoring with quarter inch jack. The unit has protections against short circuit, open circuit and R.F pick-ups and has a built-in regulated power supply.

The Unit have one stereo and two digital inputs and one SPDIF input also. The unit has only one knob on front panel which actually is a professional rotary encoder. In normal operation the display will be showing the input levels on the colour LCD display and rotating the knob will increase or decrease audio volume. While changing the volume display will automatically change to show you gain setting of the control. Adjust the volume according to comfortable listening by interactive control on the front. The input audio level will also be shown on the LCD display bar graph display.
