I am nearly sold out of the MP73EQ and will be replacing this item with the N-SONIC N73 STRIP. Please buy that instead, as it is the same item, and currently priced cheaper than the Alctron version.
The MP73EQ is a low-priced preamp with a high-end sound. It allows you to select the perfect impedance for your microphone, and allowing more tonal possibilities, making the MP73EQ invaluable to any serious engineer. Combined with plenty of gain, it also lets you get the most out of ribbons and other “low-output" microphones.
The MP73EQ has the switchable high pass filter, which lets you cut out the muddy low frequency that can cloud up your sound. Shelving high and low-frequency EQ controls with selectable cutoff frequencies give you an enormous range of tone, and semi-parametric mid control lets you dial in frequencies from 360Hz all the way up to 7.2k - perfect for fine-tuning your sound.
If you're looking for a single great preamplifier/EQ that you can use for any microphone and any sound source, the Alctron MP73EQ microphone preamplifier and equalizer is an excellent choice.
