Introduction
With new mobile devices nowadays such as Personal Digital Assistants or Ultra Mobile PCs, great possibilities
arise for working in the field and transmitting files back to your home base. The sound professional however has
one major problem with these devices: finding a decent way to connect an audio source. Almost all
manufacturers skim on options and quality in this area.
N>Trans (pronounced as “entrance”) adds a professional audio input to your mobile device and enables a new
platform for computerized audio recording. Without the need for external preamps boxes, phantom power
supplies or highly customized adapter cables; N>Trans provides direct interface to all analog audio sources.
This Compact Flash sized high quality audio card will suit the needs for reliable digital portable recording for
both professional and consumer usage.
N>Trans comes in two versions: Standard and Pro. The differences are the type of connector and the type of
microphone power supply. The standard version has 3,5 mm Jack connectors: two mono balanced inputs and a
stereo unbalanced input. The unbalanced input has a 6Volt microphone bias for electret microphone support.
The N>Trans Pro has a single 5-pin LEMO connector wired for stereo balanced input. Both inputs can supply
12V, 24V or 48V Phantom power. Both versions have a 24-bit 96kHz A-D/D-A converter onboard.
