Button 9 System Exclusive Receive Waiting

3 Basics of Equalization

Button 9: System Exclusive Receive (Waiting)

As long as this page is active, the DEQ230D will allow an external device such as a computer to transmit a new bank of 30 User programs into its User memory space. Once the external device begins sending the proper sys-ex data, the DEQ230D displays the message “Rcving,” or “receiving.” Depending on the speed of the transmission, the transfer can happen so quickly you may not see that message. Either way, when the sys-ex transmission is complete, the DEQ230D will let you know by displaying the message “Done.”

If you change your mind in the middle of the transmission and realize you’ve loaded in the wrong bank (or worse, you forgot to back up the User programs first), you can interrupt the transmission by pressing the [DOWN] button. But you’d better act quickly, as the whole process takes only about one second.

And unfortunately, as soon the message “Rcving” is displayed the DEQ230D begins overwriting programs in the User bank. If you saw that message you will have lost some User programs. But if you interrupted the transmission, you will have managed to save some of the programs.

Button 10: MIDI Out/Thru Select (Out/Thru)

Sometimes it is necessary to “daisy-chain” MIDI devices so the MIDI data from one unit will be passed through one or more other pieces of MIDI gear until it is able to reach the last unit in the chain. The DEQ230D will allow you to do that when this function is set to Thru (the default value).

The setting on this page will not affect whether or not the DEQ230D will send its memory out the MIDI Out jack. When that command is initiated (Button 8), the sys-ex data will be sent in either case.

Button 11: Sample Rate Select (44.1/48)

The DEQ230D automatically senses an incoming digital signal through its S/PDIF input and slaves its internal clock to that, whether the rate is 44.1k or 48k. But if you need the DEQ230D to serve as an A/D converter, then it also will need to be the master clock to the receiving device.

You may prefer to record the output of the DEQ230D at either 44.1k or 48k. Use the setting of this function to set the internal clock to the desired sample rate.

Button 12: Force Analog Input (Auto/Analog)

There may be times when you want the DEQ230D to ignore an incoming digital signal, but you don’t want to have to reach around to the back of the rack and unplug the cable going into the S/PDIF input. This function will help prevent that tangled spaghetti-mess of cables where no one knows whether the other end is actually hooked up to anything!

Warning! Sending a sys-ex bank into the DEQ230D will overwrite the User memory locations. Make sure you have backed up the entire User memory before you load in a new set of User programs.

DEQ230, DEQ230D specifications

The Alesis DEQ230 and DEQ230D are sophisticated digital equalizers designed for audio professionals seeking precision in sound control. Equipped with advanced features and innovative technologies, these units cater to a variety of applications, from live performances to studio recordings.

Both models include a powerful 31-band graphic equalizer, allowing users to sculpt their sound with incredible accuracy. The DEQ230 and DEQ230D offer extensive frequency coverage from 20 Hz to 20 kHz, ensuring that all audible frequencies are managed effectively. The 1/3-octave resolution facilitates fine adjustments, enabling sound engineers to target specific problem frequencies within the mix.

One of the notable characteristics of the DEQ230 series is its dual-channel operation. The DEQ230 provides individual equalization for two separate channels, making it an excellent choice for stereo setups or multi-channel applications. The DEQ230D takes this functionality even further by incorporating digital connectivity, allowing for seamless integration with digital audio systems and enhancing flexibility in various setups.

In terms of technology, the DEQ230 and DEQ230D utilize state-of-the-art digital signal processing (DSP) to deliver high-quality audio performance while minimizing latency. These models feature comprehensive output level control and provide precise metering through LED indicators, which allows sound engineers to monitor levels easily while adjusting the EQ settings.

Moreover, both equalizers come equipped with a variety of memory presets. This feature enables users to save and recall specific settings, streamlining the workflow during live events or studio sessions. The intuitive interface ensures ease of use, with clearly labeled controls that facilitate quick adjustments on the fly.

Alesis has also prioritized durability in the design of the DEQ230 and DEQ230D. The robust construction and rack-mountable chassis make them ideal for both touring and permanent installations. Additionally, the inclusion of balanced XLR and TRS inputs and outputs guarantees compatibility with professional audio gear while minimizing signal degradation.

Overall, the Alesis DEQ230 and DEQ230D represent valuable tools for any audio professional, offering precision, versatility, and robust performance in a compact design. Their combination of advanced features and user-friendly interface makes them an excellent investment for enhancing sound quality in any audio environment.
