Charteroak Peq-1 Equalizer The CharterOak PEQ-1 is an active equalizer that uses the highest quality operational amplifiers, capacitors, resistors, input transformers, and output transformers available today. The PEQ-1’s design is quite intuitive, with carefully designed switchable center frequency points and overlapping bands that are ideal for music production. The equalizer is highly clean and distortion-free, allowing for a significant increase in upper frequencies without harshness. The equalizer also has an incredibly tight and concentrated bass response and great stereo imaging, making it an excellent option for the mix bus or in a mastering situation. The PEQ1 is a switchable 16-band program equalizer with center frequencies spanning from 20 Hz to 50 kHz, designed for use as a finishing tool on the mix bus or during mastering. Specifications Frequency response: 20Hz-20kHz with a 0.4dB-3dB drop at 60kHz. Total harmonic distortion is 0.01% below 21dBu. Cross talk at low noise levels. Signal to noise ratio: -85dB (referenced to 4dBu). Maximum output: 23 dBu. The input impedance is 600 Ohms (balanced transformer). Transformer output impedance: 600 Ohms (balanced). Dimensions: Standard 2RU, 19″ length, 3.5″ height. Power requirements: 110-115 VAC or 220-230 VAC.
