NOTES

INTRODUCTION

Thank you for your purchase of the ORION DEQ 30. The latest technological advancement in car audio signal processing, the DEQ 30 is the worlds first stand alone digital 30 band 2 channel equalizer. The DEQ 30 processes all the equalization in the digital domain and comes equipped with both analog to digital and digital to analog converters. The DEQ 30 contains four preset stations called “zones” which allow storage of several equalization curves. This is especially useful in sound-off competition where the DEQ 30 presets can be set for “Sound Quality,” “RTA,” “SPL” and regular listening. The addition of a DEQ 30 to a system is a must for a competition system and for people who demand the best.

This manual is designed to answer your questions about this product. To accomplish this task, the manual is divided into several different sections according to the type of questions you may have. These sections are Introduction, What‘s in the Box, Technical Overview, System Planning, Installation, User Interface, Trouble Shooting, Specifications and Warranty. In the event you have questions not covered in this reference, please refer questions to your local Authorized ORION Dealer. Record your serial number and date:

NOTES

TECHNICAL OVERVIEW

Designed for the person who competes, the DEQ 30 is a must for all high-end systems. Either channel of the DEQ 30 can be adjusted individually or linked together. The DEQ 30 can accept direct digital inputs (TOSLINK or COAX), conventional RCA inputs or Mini-XLR™ balanced inputs. The DEQ 30 processes all equalizer functions in the digital domain.

With four separate universal presets, you can equalize for SPL, sound quality or any other sound you want. After processing, a digital output can be connected to an outboard D/A converter or done internally with an 18 bit, 192 times oversampling converter with our patented C-Lock™ anti-jitter circuit.

Analog outputs are standard RCA or balanced Mini-XLR™ with an incredible 4 volts output. For the future there is a serial data port to use with an additional controller or a computer.

TECHNICAL OVERVIEW

TRUE DIGITAL EQUALIZATION:

All equalization is performed digitally by proprietary digital algorithms. Digital equalization achieves perfect phase response. The signal-to-noise ratio is unaffected by equalization adjustments. Frequency centers, boost levels and “Q” values are exact. There is no variance like analog circuits. Additionally, digital equalization eliminates oscillations normally associated with analog circuits.

30 BANDS SEPARATE LEFT AND RIGHT ADJUSTMENT:

30 bands of equalization set to the exact frequencies on 1/3 Real Time Analyzers. Left and right channels can be adjusted individually.

4 PRESET WORKING ZONES:

4 working zones create different preset response curves for every listening preference.

ANALOG INPUT SECTION:

THE DEQ 30 uses an 18 bit balanced delta sigma analog-to-digital converter with 128 times oversampling. It accepts both RCA and Balanced (Mini XLR™) inputs. Left and right input sensitivity adjustments are fully variable and independent.

DIGITAL INPUT SECTION:

The digital input section uses a Professional Grade SPDIF receiver. It uses the same receivers used in high-end home audio and professional applications. The DEQ 30 supports 44.1 kHz and 48 kHz sampling frequencies and both TOSLINK and COAX digital inputs.

ANALOG OUTPUT SECTION:

The analog output section uses dual wide dynamic range 18 bit continuous bitstream auto calibration digital-toanalog converters (made by Phillips) with 192 times oversampling. It has low total harmonic distortion devoid of crossover distortion and incorporates digital de-emphasis. The DEQ 30 has both RCA and Balanced (Mini XLR™) Outputs. The output voltage is 4 Volts rms for the RCA outputs and 8 Volts rms (4 Volts rms output per phase) for a balanced system.

DIGITAL OUTPUTS:

Digital outputs use Professional Grade SPDIF transmitters. These are the same transmitters used in high-end home audio and professional applications. The output frequency is 44.1 kHz. The DEQ 30 supports both TOSLINK and COAX digital formats.

C-LOCK™ ANTI-JITTER REDUCTION CIRCUIT:

C-Lock™ Anti-Jitter clock recovery system virtually eliminates jitter from a digital signal. Jitter in a digital signal creates amplitude errors in rapidly changing signals. The C-Lock™ circuitry strips away the existing clock information and replaces it with a reconstituted correctly timed clock. The result is a perfectly timed digital signal.

POWER SUPPLY:

The power supply used in the DEQ 30 is a balanced high-frequency power supply. For optimal noise isolation, power and signal grounds are isolated.

COMPUTER INTERFACE:

The DEQ 30 uses a RJ-11 port that supports a IBM computer compatible RS-232 data interface. Additionally, there will be an optional remote interface that will be released in the future.

The above corrected response is not a perfectly flat curve. For good sound quality in a vehicle a flat curve may sound great when the vehicle is stopped and the engine is off. However, most people put systems in cars to listen to great music with the engine running while driving. The above response is not a mandate for good quality sound in a vehicle but one example of a frequency response that has smooth transitions from octave to octave and compensates for the road and vehicle noise. To get the best sound quality in a system, use an RTA to detect and resolve problems but use your hearing to determine if the finished product is acceptable. Because you are the one listening and enjoying the system, not the RTA, Orion brings you one step closer to a perfect system with the DEQ

30. Enjoy!
