To help with this we use Tascam 122 MkIII, Nakamichi RX505 and 680 and 600 series 3 head cassette decks when we digitise stereo audio cassettes and Teac C-3x and Tascam 234 and 238 decks for high speed 2 channel, 4 and 8 channel transfers.

We can provide the appropriately - sized USB delivery media for your files, or use media supplied by you, or deliver your files online. We can also digitise to 24-bit / 192 kHz, if required. We're happy to create any other digital audio files, according to your needs.
