Q4 Applications

Using the Q4 on voice

Connect a mic to your favorite preamp and send the signal through the Q4 to add a gentle sparkle in the top end or solidify the fundamentals in the lower mids. The Q4 lets you quickly dial in the frequencies you need without ever sounding harsh.

Using the Q4 to accentuate tracks

The Q4's musical sounding circuit can make any track sound its best! Simply send an instrument or pre-recorded track into the Q4 and explore! The Q4 is super easy to use. Add some high end to accentuate the air, some bass to warm up the bottom and pull out some mids to blend tracks together.

Using the Q4 on program material

The Q4's warm sounding class-A discrete circuit is the perfect medicine to warm up digital tracks and give them old-school 'vintage' analog character. With 12dB of boost and cut on each frequency, you have plenty of power to shape and create your sonic signature.
