Product Description
The dbx 580 Microphone Preamp is an ideal companion for your microphones. It offers sonically - transparent gain, enabling you to uncover the details and unique audio signature of even the most specialized microphones. This preamp can convert the low - level output signal of microphones into a high - level, high - current output, allowing for direct connection to the line - level inputs of mixers, samplers, or other recording devices that accept line - level analog input.
With its modular 500 Series design, the dbx 580 provides up to 60dB of gain. It comes with a variable - frequency Low - Cut Filter, unique Low and High Detail Equalization Controls, a 20dB Pad, Polarity Invert, +48V Phantom Power, a Front Panel Instrument Input, VU Metering, and a Peak Indicator.

Using the dbx 580 Microphone Preamp is a breeze. First, connect your microphone to the input of the preamp. If you're using an instrument, you can use the 1/4 - inch front - panel instrument input. Then, connect the output of the preamp to your mixer, sampler, or other recording device that accepts line - level analog input.
Adjust the gain to your desired level. You can get up to 60dB of gain, which is quite powerful. Use the variable - frequency Low - Cut Filter to remove unwanted low - frequency noise. The Low and High Detail Equalization Controls can help you fine - tune the sound according to your needs.
Remember to be careful when using the 20dB Pad. When it's enabled, it can handle higher input levels. Also, make sure your power source provides +/- 16V DC as required.
For maintenance, keep the preamp in a clean and dry place. Wipe it gently with a soft cloth if it gets dirty. Don't expose it to extreme temperatures or humidity. If you notice any issues, it's best to have it checked by a professional.
