- Excellent flatness of frequency response across the full 20dB attenuation range.

I bought a 4-way distribution amplifier to replace an old one made by another company. Ordering and delivery went as planned. The amplifier is a solid piece of kit, built to last. Easy to fit. Works well. Nice one !
