Keep input levels adjusted so that the DSP output levels are below -6dB. There is no output gain control on the 1100/1124 and digital clipping will occur if the digital output exceeds -3dB. So, again, keep the input level low enough to not exceed about -6dB on the digital output of the 1100/1124.
In some filter combinations, you may notice a weird processor hum or low tone. This seems to be a digital audio loop of some kind. To remove this processor tone, simply change your memory channel to the ' - - ' channel just below memory ch 1. The tone should disappear. Then, return to the memory channel you were working with and see if the tone is gone. If it is, then press the 'STORE button twice to save the program. The saved program should now be tone free!
If you create a program that you like, and you want to make a backup, here is a nice way to do it. Let's say you are using only the LEFT channel for your EQing. Once you have set up your Left channel program, press and hold the 'ENGINE L' button then the hit the 'ENGINE R' button and the program will copy itself to the Right channel. Now, if you ever accidentally 'Mess-up' the program, just copy the Right Channel back to the Left channel by pressing and holding the 'ENGINE R' button, then hit the 'ENGINE L' button to transfer the Right channel to the Left channel.
The DSP1100/1124 Software programs version 1 & 2 are downloadable by clicking the link at the top of this page or by selecting it from the 'SSB TX Setup' menu. Version 2 is an updated version of version 1 but still has some significant bugs, so beware! For a graphical representation of your EQ curve, version 1 is still a better version for this purpose.
The DSP 1100/1124 is connected to your computer via midi cables from your computer sound card MIDI in/out connectors (if available) or more typically via your computer's Game/MIDI port. So, there are two possible ways to interface the 1100/1124 to your computer:
1) A pair of standard midi to midi (in/out) cables if your sound card has standard midi in/out jacks.
2) A special cable with 2 DIN-5 Male midi connectors on one end and a DB-15 Male plug on the other end for game cards that use the DB15 in/out jack.
There are also cables available that have a DB-15 Female connector added for a Joystick passthrough if you play games that require the use of your joystick. These cable costs about $20.00 and is available at most music outlets.
The software is very useful, even if you only want to use it to display a graphical image of your programmed EQ curve. Just plug in your settings in the software and you will see a nice graph of your resulting curve. Also, the software will let you see how your Frequency / Bandwidth / Gain settings effect the graph to better understand the relationship of these settings with a graphical picture.
NOTE: To perform a hardware reset of the unit to factory default, do the following:
1) Power OFF the DSP1100/1124
2) Press and hold the 'STORE' and 'FILTER SELECT' buttons while turning on the unit.
(Keep pressed for about a second after the DSP-1100/1124 is tuned on)

Controlled remotely from a PC via the downloadable BEHRINGER Amp Remote control software. This manual first describes the panel controls and connection points before delving into the DSP functionality. Special sections describe how you can program the DSP by using either the amp's front panel controls, or by using the Amp Remote software. According to several user reviews, they have praised Behringer FX2000 Virtualizer 3D for the produces good reverberation effects; adds depth to the music; found the basic controls easy to operate; plenty of effects to chose from. Also, some users have complained it for the four-character display is limiting. Image source: selyaproduct.com. Behringer Virtualizer PRO. Behringer DSP-1000 PRO Virtualizer. Digital Dual-Engine 24-Bit Multi-Effect Processor, fully programable either with alpha dial or MIDI editing software provided free by the manufacturer. The editing with led display is not comfortable. The sound is crystal clear but also pretty sterile.
