NOBSOUND EQ9 9-Band Stereo Analog Equalizer with 2-Channel Selector

The Nobsound EQ9 is a 9-band analog stereo equalizer designed to precisely refine the sound reproduction of a home HiFi or car audio system. Operating as an audio preamplifier with independent frequency correction, it allows adjustment of nine distinct frequency bands ranging from 20Hz to 16kHz with an adjustment range of ±6dB for each band (20Hz / 60Hz / 125Hz / 250Hz / 500Hz / 1KHz / 2kHz / 6KHz / 16KHz). The EQ9 features two stereo RCA inputs as well as two stereo RCA outputs, allowing multiple audio sources and devices to be connected simultaneously without constantly unplugging cables.

Designed to preserve the integrity of the audio signal, the EQ9 offers excellent technical performance with a frequency response from 20Hz to 20kHz (±0.4dB), extremely low harmonic distortion of only 0.001% at 1kHz, and a signal-to-noise ratio greater than 111dB, ensuring detailed, clean, and faithful sound reproduction. Its 2V nominal output level and 1V input sensitivity ensure excellent compatibility with most DACs, CD players, amplifiers, and analog audio sources.

The EQ9 also features a Bypass mode allowing the equalization circuits to be completely disabled in order to achieve direct audio signal transmission between inputs and outputs without additional processing. A left/right balance control is also included to precisely adjust soundstage positioning and compensate for any channel imbalance. The entire unit is housed in a robust black aluminum chassis offering excellent protection against electromagnetic interference while ensuring an elegant and durable finish. Compact with dimensions of 220 x 65 x 21 mm and a weight of 457g, the Nobsound EQ9 provides a simple and effective solution for customizing and optimizing the sound reproduction of a HiFi setup.
