Home 10 Band Equalizer Basic Equalizer CW I'der & Pulser PSK 31 Distortion Meter Sound Card Manager


 

Below is list of tested sound cards and notes on setting up each sound card. This is not complete list of sound cards that will work with the RoMac 10 Band Equalizer, many other sound cards may work and give excellent results. Most sound card problems that we have seen to date are usually a noisy microphone input. Sometimes checking both the +20 dB and -20 dB in the sound card level dialog box will help solve this problem. This may seem counter intuitive, but the +20 dB controls the hardware on the sound card, where as the -20 dB selection is implemented in the equalizer software.

A dynamic microphone (-55 dbm) has been used for all the tests.

Windows 2000 & XP have an option to use the "Line In" as the audio source when the equalizer is in a transmit mode. This will usually require some kind of microphone preamp in order to drive the sound cards "Line In" with a Microphone. Windows Vista 32 bit, has this capability built as part of the it's operating system.

Sound cards are rated 1 to 5 with an asterisk

As we test more sound cards in the future the results will be posted here.

Mic is a bit noisy, but using the +20 dB and -20 dB settings together will quiet it down.

With a Mic preamp use the -20 dB setting with the level wide open, and adjust the microphone preamp for proper levels.

Microphone seems very quiet under Windows 2000 & XP
