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.
