Product Description
1. Product Summary
Suitably used in bi-directional transmission (can be reserved) and signal equalization of multi-class trunk transmission or high-required distributive network. Adopt PHILIPS, NEC imported power doubler modules. Audio pre-amplifier is low-noise microwave tube push-pull amplifier to insure enough gain. It has 1 input and 2 outputs, and each connection has over-current protection. The output branch or distributiveness can be changed following it. Double-equalizer is used, so adjusting multi-class transmission flatness is simple and convenient. Attenuator and equalizer are plug-in, so customers can choose fixed or adjustable style. High-reliable switch power (or linear power) and strict waterproof and anti-thunder design insure steady durative work.
