Yamaha YDG 2030 Graphic EQ Black

2 Channel digital equalizer
MIDI Interface - The MIDI Interface allows EQ programs to be recalled and parameter changes to be made from a MIDI sequencer, computer or similar device. The MIDI interface also features a bulk dump function that allows the contents of the YDG2030 memory to be transferred to any MIDI device capable of recording bulk data.
"Flat" key sets all gain parameters to "0" in one operation

20-bit digital graphic equalizer with intuitive interface and outstanding performance.
Superior Audio Quality - 110-dB dynamic range, precise response from 20 Hz to 20,000 Hz and total harmonic distortion of less than 0.007% (emphasis on). 20-bit A/D and D/A converters sampling at 44.1 kHz.
2-channel 30-band Format With switchable Gain - It features a 2-channel 30-band EQ format with 1/3-octave bands from 25 Hz to 20 kHz. Extra control flexibility is provided by switchable +/-12 dB or +/-6 dB gain ranges.
LPF, HPF and Four Notch Filters per Channel - It has programmable high-pass and low-pass filters as well as a group of four notch filters with variable frequency and bandwidth.
40-program Memory - Up to 40 complete equalizer setups can be stored in internal RAM memory and recalled as needed.
Independently Programmable Channel Delays - Each channel also provides a variable delay parameter that can be used for phase alignment, speaker distance compensation, and other applications. The delay range is from 0 to 714 milliseconds, adjustable in sub-millisecond steps.
Feedback-seeking Sweep Function - The YDG2030 includes a sweep function that lets you sweep a preset amount of boost or cut continuously through all bands. Once the problem band has been located, you can easily compensate in the normal way.
Professional Analog Inputs and Outputs - Both the YDG2030's inputs and outputs are electronically balanced with XLR-type connectors. Extra I/O versatility is provided by independent -20/+4 dB level selectors for the inputs and outputs.
Expanded EQ Network Capability - The network can include up to 31 YDG2030 units to efficiently handle even the largest and most complex sound reinforcement systems.
