Comments about TECHNICAL PRO EQS7150 - Pro Dual Equalizer:

I purchased this EQ from another online seller [...] I hooked it up to a decent system with Harmon Kardon reciever and B&W speakers. Turn it on and there is a lot of flash but little quality in the fidelity of the sound. The LEDs on the sliders blink on and off at a rate of about once per second, alternating one next to the other like a Christmas tree. The Graphic display of the equalizer, which is supposed to display the sound spectrum is worthless. I noticed that it was responding to the music WITHOUT the EQ being attached to anything. It basically just responds to mid to low frequencies, and if you change the tone, the graphic display doesn't change. WHAT WE HAVE HERE IS YOUR BASIC JUNK ELECTRONICS FOR KIDS WHO WANT BLINKY LIGHTS. When hooked up the sliders do seem to change the appropriate frequency range of the sound, but there is an overall loss of crispness to the sound. Overall this purchase was a waste of money for me.
