Technical Help

Connectivity options
Connection via Bluetooth

Thanks to aptX Bluetooth, the Coturn CT-1 has the best possible transfer rate and the cleanest sound. In particular, if the signal source and receiver are capable of aptX and are connected to each other via Bluetooth, the quality increases significantly.

Headphone output

The CT-1 is one of the few portable turntables that has a headphone jack

Neutral audio output

The line-out output (3.5mm jack) is neutral. This means that the CT-1 can not only be connected via Bluetooth, but also with classic devices and systems via cable / jack to cinch.

The portable record player has a belt drive

Which needle is used?

An Audio-Technica AT 3600 is used as the stylus, but it can be easily swapped out or replaced.
