The Latest Models Have Direct Constant Pressure Capability

The Constant Voltage Transformer(CVT) was the first series to independently select high and low impedance operation for specific channels, and the CDi and amps carry on that tradition with carefully selected power levels and features for integration into fixed installation designs.

70V (dual mode) and 140V (bridge mode) as well as low impedance (2/4/8 ohm) operation are available. The CTs Series amplifiers offer direct constant voltage (70V/100V/140V/200V) or low impedance (2/4/8 ohm) operation. In dual mode, the CTs 600/1200 can power 25/50/70V lines; the CTs 2000/3000 can power 25/50/70/100V lines. In bridged single-channel mode, CTs 600/1200 can be powered from a 140V line; CTs 2000/3000 can be powered from both 140V and 200V lines.

One channel can drive low-impedance speakers while the other channel drives speakers with 70V transformers. This makes it easy to set up a system with large low-Z speakers for local coverage and distributed 70V speakers for distant rooms, all using just one amplifier.
