AT 10Z volume control is made of a control circuit with a 6 position (5 + off) selector. It can be inserted between the amplifier “4 Ω” output and the inputs of 1 or more loudspeakers having a 4 Ω total impedance. Features Constant impedance attenuator for speakers with minimum impedance 4 Ω Universal mounting on any s...
AT 20T volume control is made of a control circuit having a 6 position (5 + off) selector and a separated transformer. It can be used in 100 V line systems to adjust the volume level of a loudspeaker group having a total power not exceeding 20 W. All connected loudspeakers shall have 100 V line matching transformers. It can be set ...
AT 40T volume control is made of a control circuit having a selector and a separated transformer. It can be used in 100 V line systems to adjust the volume level of a loudspeaker group having a total power not exceeding 40 W. All connected loudspeakers shall have 100 V line matching transformers. It includes a 24 V dc override relay to ei...
CP 52 selector can be used in 100 V constant voltage systems to select 1 out of maximum 5 available lines. The maximum total power of the output load cannot exceed 120 W. It includes a 24 V dc override relay to bypass the 6 position (5 + off) selector and route the first input (J1 terminal) directly to the output. CP 52 can be installed on...
The 6 (5 + off) position selector CT 61 shall be matched to a (not included) RCF TL 128 line transformer (or equivalent), in order to get a volume control for a loudspeaker group (in a 100 V constant voltage system) having a total power not exceeding 120 W. All connected loudspeakers shall have 100 V line matching transformers. It includes a ...
The TL 128 transformer can be used in sound systems with constant voltage loudspeaker lines (usually 100 or 70 V) to adjust the power of one or more loudspeakers equipped with line transformer and having a max. total power not higher than 120 W. Thanks to its sockets with decreasing transformation ratios, the voltage applied to loudspeakers can...
