TVA-110 ACL Channel Amplifier with AGC

TVA-100ACL-e.jpg

* High selectivity
* Automatic energizing of antenna preamplifier and energizing block in case of fault   (non-personal operating)
* Output level control
* Automatic output level control
* RF input for signal summation
* Plug-in design
* F-type connectors

It is intended for set channel amplification when the input signal level is changeable. A possibility of antenna preamplifier energizing and amplifier cascading: input cascading (in case of several channel reception by one antenna) and output cascading (signal summation from separate amplifiers).

Note: Energizing block of the antenna amplifier is effected when load current exceeds 100 mA. Operability of a TVA-100 and a TVA-110 ACL channel amplifiers is kept. It is necessary to cut off a 12V/0,3A energizing of the channel amplifier (TVA-100, TVA-110 ACL) for a short time to resume energizing of the antenna preamplifier (provided that current overload is excluded).
