Tailor Your Music

The Linertec LT-7 pre-amp equalizer is a 4 band parametric equalizer and preamp engineered to give you precise control over your receivers output while also providing efficiency to your amplifier and sound system.

Designed with a 12db boost or cut adjustment control for each of your high, midrange, midbass and bass bands. The LT-7 allows you to have the freedom to tailor your music and fine-tune low frequencies to get the bass kicking the way you like.

The LT-7 also functions as a line driver/preamp. With an output voltage of 7V RMS, the master volume knob lets you boost the signal up to the level that your amplifiers need to play at maximum efficiency while lowering the noise floor of your system, even through long wire runs. With a compact body the LT-7 pre-amp equalizer will be an easy and welcome addition to your sound system.
