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.

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. See Also

Product Information for model: YDP2006. Description: Digital parametric equalizer
20-bit digital parametric equalizer with graphical interface and outstanding performance.
MIDI Interface - A MIDI interface that 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 memory to be transferred to any MIDI device capable of recording bulk data.
Unmatched Audio Quality - 110dB dynamic range, precise response from 20 Hz to 20,000 Hz, and total harmonic distortion less than 0.007% (emphasis on) 20-bit A/D and D/A convertors sampling at 44.1 kHz.
A Choice of EQ Modes - There is a choice of two EQ modes. In the stereo mode it offers 2-channels of 6-band parametric EQ while in the mono mode you get a single channel of 12-band parametric equalization. In either mode you have +/-12 dB gain control in each band, plus Q control ranging from 0.5 to 10.
LPF, HPF, and Multiple Notch Filters - In the stereo EQ mode, independently programmable high-pass and low-pass filters as well as a group of four notch filters with variable frequency and bandwidth. In the mono mode the YDP2006 provides the same high-pass and low-pass filters with no less than eight programmable notch filters.
40-program Memory - The YDP2006 stores and recalls up to 40 different EQ programs as required. You can recall via the front-panel keys or the MIDI interface or Y-485 bus.
Independently Programmable Channel Delays - For phase alignment and speaker distance compensation, each channel provides a variable delay parameter that can be set anywhere from 0 to 714 milliseconds in sub-millisecond steps.
Easy Programming Interface - A graphic LCD panel is a graphic representation of EQ curves, simultaneous display of related parameters, and comprehensive display layouts. Another feature is the provision of three rotary encoders for data entry. In addition it has a parameter copy function that allows parameters to be copied from an existing program and then edited as required.
Reliable Balanced Analog Inputs and Outputs - Electronically balanced input and outputs with XLR-type connectors. Versatility is provided by independent -20/+4 dB level selectors for the inputs and outputs.
Multi-equalizer Network Capability - Up to 31 YDP2006 units can be included in the network. All parameters can be remotely accessed and controlled from a single master YDP2006 unit or a computer running Yamaha QS1 Digital Equalizer Control Software.
