The leads are coloured red and green for easy channel identification. The unit is powered by a single PP3 battery. It can also operate in single-channel, mono mode where just the red channel is operational. Since the DAT is a two channel recorder, the right channel in mono mode is a -12dB version of the left as insurance against overload and clipping. In this mode the battery drain is also halved.
Operation is by a three position rotary switch which prevents accidental switch-on.
The unbalanced 'domestic' level output to the DAT is via a Sony miniature jack. Frequency range DC to 20kHz. Extras Electret Connectors Electret microphones are intended to be used with DAT machines such as the TCDD7. Due to the mediocre performance of the microphone preamps in the DAT, improved performance can still be achieved using the Clarity Preamp with inline 'pads'. These are available as an option.
