Orion DEQ 30 - Manuals

ANALOG OUTPUT SECTION: The analog output section uses dual wide dynamic range 18 bit continuous bitstream auto calibration digital-to- analog converters (made by Phillips) with 192 times oversampling. It has low total harmonic distortion devoid ofcrossover distortion and incorporates digital de-emph...

INSTALLATION The installation of all ORION components will determine the overall performance result. Improper installation will not only limit the performance of your ORION system but also potentially compromise the reliability of thisdigital processor. To ensure proper sonic results and component r...

POWER CONNECTIONS 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. T...

DEQ 30‘s power supply is an ultra-quiet balanced high-frequency supply. All power and signal grounds are isolated for complete noise rejection. • Power connections made through large four terminal removable connector. • Connect 12V+ to the battery through fuseholder. This connection provides +12V ma...

ANALOG INPUTS Time alignment errors are caused by speakers that are located at different distances relative to the listening position. Time alignment errors are difficult to detect only using an RTA. In some cases, time response errors can beindicated by a shelving effect of a particular driver (in ...

The DEQ 30 can accept either balanced (Mini-XLR™) inputs or RCA inputs. However, only one input can be chosen per installation. The DEQ 30 was not designed to be a multi-source input selector. The systemdesigner/installer must determine which configurations will work and yield the best sound quality...

SETTING ANALOG INPUT LEVELS 1. Install DEQ 30 into your system. 2. With your source unit volume control set at a low position, test the function of the system. Oncesatisfied proceed to the next step. 3. Turn the gain controls of the DEQ 30, your amplifiers and other components in your systemto their...

8. Disconnect the output of the DEQ 30 from the rest of the system. 9. Leaving the source units volume control alone, slowly increase the left gain of the DEQ 30 untilthe “CLIP” LED indicator becomes illuminated.The output of the DEQ 30 is currently clipped. 10. Turn down the left gain control until...

DIGITAL INPUTS Roll-off response errors are caused by deficiencies in driver performance, driver placement, enclosure design and vehicle acoustics. This type of response error usually is inaudible in all but the most demanding music.However for competition systems potential points can be lost with a...

ANALOG AND DIGITAL OUTPUTS Off-screen response problems are often a result of a system with a large quantity of woofers. In some situations, this may be a desirable result. If so, look for smooth transition from octave to octave. If your goal iscompetition, you must have all the bands on display at ...

The internal analog to digital converter uses dual 18 bit resolution bitstream auto calibration digital-to-analog converters made by Phillips. It has 192 times oversampling and features low harmonic distortion, no crossoverdistortion and digital de-emphasis for smooth highs and controlled low freque...

USER INTERFACE The user interface controls are designed to be concise and user friendly. Listed below are thedescriptions of the user interface functions. DIGITAL DISPLAY ZONE Indicates which preset Zone you areworking in. There are four preset zones that store all information. To access the differe...

USER INTERFACE LED INDICATORS “CLIP“ - When illuminated, indicates the EQ has clipped its output. There are three solutions to this problem:Reset input gains, turn down source unit (if using analog input) or lower boost on boosted frequencies. “L” & ”R“ - Indicates which channel is to be equaliz...

USER INTERFACE CONTROLS Output Level Incompatibility Problems are caused by a miss-match in output levels between woofers, midranges and tweeters. In the above graph, the midrange output level is lower than what is needed to match the woofersand tweeters. This is usually an easy problem to solve wit...

• Pressing the left and right sides of the main user interface button selects one of 30 frequency bands in 1/3 octave increments from 25 Hz to 20 kHz. • Pressing the up and down sides of the main user interface button changes the output level of selected frequency band from -12dB to 12 dB in 1 dB st...

BASIC EQUALIZATION The DEQ 30 is a highly advanced signal processor. However, “highly advanced” does not mean difficult to use. There are two different levels of use for the DEQ 30. This section explains the basic utilization of the DEQ 30. Toproceed, it is important that you familiarize yourself wi...

Before you begin equalization it is strongly recommended that you accomplish the following: • Choose good quality speakers (ORION, of course). • Determine the best location for the midrange and tweeters. Speaker placement will make the most difference in sound quality, imaging, etc. • Choose a woofe...

While listening to your reference music, listen for irregularities in your system. These irregularities can best be described as tonal qualities your hearing finds offensive or irritating. To better locate a particular frequency rangethat needs correction, boost individual frequency bands (one at a ...

ADVANCED EQUALIZATION PERFECTLY FLAT CURVE This section is designed for people who will use the DEQ 30 in competition or people who desire the ultimate performance in their system. The DEQ 30 not only performs all of the equalization in the digital domain, it also hasthe ability to adjust equalizati...
