How An Equalizer Is Used
The Planet Audio PEQ15 parametric equalizer is a high-fidelity signal processor/preamplifier that allows you to control the relative levels within the audible frequency spectrum of a stereophonic system. It is intended for use in a car audio system which includes amplifiers in a signal path after the equalizer, and provides front, rear, and subwoofer low level outputs via RCA connectors.
Specifications
- Front/Rear EQ center frequency ranges: Low (20-70 Hz); Low/Mid (150-400 Hz); Mid (1.5-4 kHz); High (4-20 kHz)
- Sub channel EQ crossover range: 50 – 250Hz
- Equalization range: +/- 18 dB (boost/cut)
- Frequency response: 10 Hz – 50 kHz (+/- 1dB)
- Signal to noise ratio: 110 dB (ref. 1V input)
- THD: 0.005%
- Channel separation: 82 dB (at 1kHz)
- Output impedance: 50k Ohms
- Power supply: 11-15V negative ground
- Output voltage: 7V
- Dimensions: (7.2” W x 3.8” D x 1.3” H)
