 Triton
- USB Audio Interface
| The
Triton is a USB Audio Interface, intended for acoustical
measurements. The analog inputs and outputs operate
phase-synchronously, thereby allowing the use of deconvolution
techniques, such as with MLS and sine sweep measurements.
USB's Plug & Play architecture and the compatibility with
native Microsoft™ Windows™
and Apple Computer™ Mac OS drivers enable instant use
without driver installation.

Signal
levels report
Each
individual Triton is supplied with a measurement report of the accurate
full scale input and output voltage levels at 1 kHz.
Applications
-
Acoustics
and vibration measurements
-
Electronic system measurements
-
MLS
or sine sweep based measurements
-

Due
to its small size, the Triton fits easily in your pocket. |

Input
attenuation
To
attenuate the input voltage or to increase the input impedance,
you can use an input series resistor, which forms a voltage
divider with the Triton input impedance. The table below shows the
attenuation for some standard E96 series resistors. You can mount
yourself resistors in the cable plugs, or order attenuator cables from
Acoustics Engineering.

Input gain
An
input gain exceeding 0 dB is available on request. The additional gain
will add a single pole/zero high-pass cutoff in the input frequency
characteristic. The cutoff frequency is given for several gains in the
table below.
