Description: DACT Line Stage Linear Pre-amp
CT-101 Pre-amplifier Line Stage
The DACT CT101 is a linear 2-channel wideband audio buffer / pre-amplifier. It is built on a compact PCB, which together with the use of SMD components yields a very short signal path. The CT101 is built as two mono pre-amplifiers on one PCB and can be powered by two individual supplies for dual mono operation if required. The active devices are special ICs, and the power supply connections are decoupled with SMD capacitors.

DACT CT101 x3 with 6-gang stepped attenuator for AV / home theatre systems.
Use the DACT CT101 to build an active high quality 2-channel audio pre-amplifier. One of DACT's stereo CT2 stepped attenuators can be solder directly onto the PCB to adjust the volume. This is an almost ideal pre-amplifier for sources like CD-players. You may add DACT's CT3 audio input selector switch and / or CT4 balance control to make a pre-amplifier with more features.
