I N T R O D U C T I O N A V A N T- P R O P O S E I N F Ü H R U N G I N T R O D U C C I Ó N Amplifiers designated by the letter "V" in their model number are designed to drive 70-volt distributed lines directly, without output transformers: These models are the 2-channel CX 302V, CX 602V, and CX 1202V, and the 4-channel CX 204V. They can be bridged— Channel 1 + Channel 2, and for the CX 204V, Channel 3 + Channel 4— to drive 140-volt lines in mono.
