Like New In Original Box!

Dont wait any longer to improve the sound and performance of your stereo system! This 10-band frequency equalizer gives you total frequency control and sound contouring of your home stereo. It has a very wide frequency response range (5 - 50,000 Hz). The frequency control range is from 31 - 16,000 Hz. This unit is used but is in very good condition. It was used only with my home system in a clean, smoke free environment. It will make a fantastic addition to your stereo system. I used this EQ with a vintage Kenwood amplifier, some Bose 201s and a passive subwoofer and you wouldnt believe the sound. If youve never experienced the versatility that an EQ brings to your stereo system, dont wait any longer. The original owners manual and packaging is included.


IMX Expander - The expander allows you to adjust the separation between your stereo left and right channels. The result adds clarity and depth to the mix. This is especially useful when dubbing muddy sounding cassette mixes. The expander has a slider to adjust the effect level & can also be turned on an off on the front of the unit.

Spectrum Display - The dynamic spectrum display shows the relative sound level of each frequency band in real time. It is adjustable by a slider control on the front of the unit.

Bypass - This feature allows you to bypass the equalizer. It is useful when comparing the mix to the unprocessed signal.

Tape Dubbing - Lets you copy from one tape deck to another. A switch on the front of the unit controls this feature.

Tape Monitoring - Lets you listen to the recorded sound. A switch on the front of the unit controls this feature

Display Level Control - Lets you adjust the display lights to best represent the signal levels.
