Detailed Product Description
Extending amplifier
·Adopting GaAs or power double module output stage with high output level and low distortion feature.
·Components are modularized design, easy to maintain and upgrade.
·Two-ways separate return channel, changeable return channel attenuator, output level could be controlled flexibly.
·High-grade switch power supply with +24V1.5V current, 40~90VAC voltage ensuring the security and reliable operation.
·With automatic gain control function to make sure there is stable output level within the certain range.
