Introduction Congratulations on the purchase of your new Midiman EQMan Programmable Graphic Equalizer! The EQMan’s revolutionary hardware and software design allows your PC to apply graphic equalization to any stereo audio source under the complete control of your computer.
EQMan Features The EQMan can be used to enhance a number of line-level audio applications including the following: • Use the programmability of EQMan in the effects loop of your mixing board to automate mix downs. • Use the EQMan to equalize the output of a PC soundcard. • Use the EQMan with a MIDI sequencer to do automated filter “sweeps” for interesting effects.
“Aux In” Jack The “Aux In” is an auxiliary input which bypasses the equalizer stage of the board. Its line-level stereo signal feeds directly into the EQMan’s stereo volume control circuitry, where it is mixed with the Main In signal that exits the equalizer stage. Because the Aux In audio signals bypass the equalizer stage of the board, they are not affected by the equalizer settings of EQMan.
Hardware Installation Each adapter card in a computer must reside at a unique “address” in order for a computer to function properly. If two or more adapters are set to respond at the same address (this is known as an “address conflict”), the computer will operate in a random or inconsistent manner, if at all. To avoid address conflicts, the EQMan board has a configurable address, allowing it to be adjusted to work properly in practically all personal computers.
The program FINDPORT.EXE does its best to determine port addresses available for use with the EQMan card. Choose one of the free addresses reported by FINDPORT and use the chart below to set the EQMan ADDRESS jumpers to that address. It’s also a good idea to write down the selected address as well as some alternates. You may need these addresses later to run the diagnostics and install the EQMan Windows Driver.
Fig. 1 here Factory Default Jumper Settings Physical Installation The EQMan should be installed into your computer only after a potential address setting for the card has been determined and properly set on the card itself. Make sure you have performed the above instructions related to address selection and that the EQMan jumpers have been set accordingly. Only then should you proceed and physically install the EQMan. When ready to install the EQMan in your computer, follow these steps: 1.
DOS prompt. If you are in Windows, exit Windows completely, to DOS, then start the program from the DOS prompt. When you run EQMNDIAG.EXE, you will see the main screen pictured below. You may change the cursor (=>) line by pressing your computer’s up/down arrows, then press the key to cycle through various parameter settings for that line. As a shortcut you may also select a line by pressing the key associated with the first letter of the desired line.
range, and treble frequencies. Listen to the audio output and verify it with what is being displayed on the computer screen.
EQMan Software The EQMan requires software in order to be a useful tool. There are three groups of software included with the EQMan: Diagnostics, Windows Remote Control, and the Windows drivers. Diagnostic software is discussed in the Installation part of this manual, so this section will address the operation and relation of the other software items. Drivers MIDI application software communicates with the EQMan via software “drivers.
Included with your EQMan is Windows Remote Control Software. The Remote Control software is actually two separate applications, an EQ application and a Volume Control application, which allow you to configure and control the EQMan card. These applications are used to change EQ and Volume settings on-the-fly, as well as act together as an EQ/Volume “program” editor/librarian application. Windows 3.1/3.
Windows 95 Driver Installation 1. Open the Control Panel and select “Install New Hardware.” Then press the “Next>” button. 2. When prompted to automatically search and detect installed hardware, click the “No” radio button. Then click “Next>”. 3. Scroll down in the list box and select “Sound, video and game controllers.” Click “Next>”. 4. Click on the “Have Disk...” button. 5. Insert the Midiman driver disk in your floppy drive.
Occasionally some users may need to make fine adjustments or customizations in the Windows drivers. This is accomplished through the Windows Control Panel. Within the Control Panel is a Drivers applet (in Windows 95 choose the Multimedia applet) that allows you to select an installed Windows driver and modify its settings. Open the applet, highlight the Midiman EQMan driver selection and click on the Setup button. This will open the Driver Setup dialog box.
Fig. 3 goes here EQMan Driver Advanced Setup Dialog Box The Midi Channel Assignment is used to set the MIDI channel on which the EQMan operates. To a MIDI application such as a sequencer, the EQMan looks just like any other MIDI device (i.e., a synthesizer or drum machine) and responds on its own MIDI channel. The MIDI channel is important when sending MIDI program change, volume, pan and continuos controller messages to the EQMan. The default MIDI channel is 1.
Remote Control Software Operation The Remote Control Software is actually two separate applications: the EQMan Remote Control and EQ-Vol. EQ-Vol controls the output levels of the EQMan board only. EQMan Remote Control controls all graphic EQ settings and indirectly the output levels. It is also the home of the EQMan program editor/librarian function that allows you to load/configure/store sets of different EQ programs. An EQ program contains settings for all EQ bands and volume settings.
The File Button The File Button pops up a menu of selections: Open File..., Save File..., About..., Exit. Open File... Lets you select a stored program map file (a group of 16 EQ programs) to load from disk. The suggested default extension for a program map file is .EQM although you may name them whatever you choose. The included file FACTORY.EQM contains some factory default EQ programs for your use. Save File... Allows you to save the current map (16 programs) to disk.
the Rom, save the current programs to disk as a map file before using the Read All function. Write One Allows you to select and write any App program to and EQMan Rom program. The selected EQMan Rom program is overwritten. Write All This choice writes all App programs to Rom where they can be accessed via other MIDI applications. All Rom program locations are overwritten. View Rom Programs This selection displays the current application program map.
down during sequences sending MIDI EQ commands, either choose a slower update speed or close the Remote Control application altogether. Volume Fader App You may choose to display the Volume Fader application (EQ-Vol) or not. If “Show” is selected, EQ-Vol is opened automatically when you open the Remote Control and closed when the Remote Control is closed. The Current Program Status In the middle of the control/status bar, the current program status is displayed.
The EQ Flat button automatically flattens (sets gains to 0 dB) all EQ bands. This basically acts as an EQ bypass and does not affect the volume settings. When Flat is pressed again, the previous EQ settings are restored. In effect, the Flat button is a handy way to compare your current EQ settings with a bypass setting. The Map Button The Map button accesses the current program map in Remote Control application memory. When pressed, it pops up the following dialog box: Fig.
Configuring Windows Applications to Use EQMan Once the Windows drivers for the EQMan have been installed, you will need to configure your MIDI applications to take advantage of the EQMan Windows drivers. NOTE: The supplied Remote Control and Volume applications automatically detect the presence of the drivers and do not to be specially configured for operation.
Programs 1 through 16 are the user-defined programs, and program 0 is always an EQ-Flat (bypass) setting. Program 0 is hard-coded and may not be modified. Volume Control and Pan Messages The EQMan driver accepts Volume and Pan Controller messages to set the output levels of the left and right channels. The standard pan values range from 0 to 127 with 0 being hard-left and 127 being hardright.
Some General Thoughts About EQ A lot of beginning audio engineers tend to misuse or overuse equalization. While it is one of the most important tools in an audio engineer’s bag of tricks, like any other tool, there are some basic ground rules (like never put your hand in front of a buzz saw). 1. Signal-to-Noise is improved drastically when the input signal to the EQMan is a bit “hot”.
Once again, the EQMan automation features can enable you to add just a little and change it back before your listeners start yawning. 7. Use your ears! Some engineers will automatically set up a particular EQ for an instrument without listening to the specific instrument first. Listen first. Not all acoustic guitars sound the same; that's why some are worth thousands of dollars and others are good for emergency umbrellas.
Troubleshooting If you are having problems using your EQMan it is probably a good idea to reread this manual and make sure you have properly installed the card. If you can't find the source of your difficulty check the following typical fixes: SYMPTOM: The computer won't boot with the card in. Everything is fine without the card. (This may include strange error messages.) SOLUTION: Run through the INSTALL procedure given above and make sure the card is recognized at the ADDRESS selected.
SYMPTOM: Audio is present but distorted. SOLUTION: Make sure the input signals are not too hot for the EQMan. Make sure the output volume setting of the EQMan is not too loud for whatever it’s driving. Make sure the source material is not distorted itself. SYMPTOM: The EQ seems erratic and confused when changing presets. SOLUTION: Hardware Speed may need adjusting in the Windows Driver. Do so from the Advanced Setup in the Windows Driver.
