RS-232, FIRMWARE UPDATE
The U-150 amplifier RS-232 terminal is used mainly for firmware updates.
You can check for U-150 firmware updates on the Aavik Acoustics homepage.
TRIGGER OUTPUTS
The U-150 amplifier is equipped with two DC trigger outputs. These can be used
to power-on power amps, subwoofers and other equipment together with the
amplifier. When the amplifier is switched on (not in standby mode), the trigger
outputs will supply 12VDC. They can supply up to 40mA total.
DIGITAL INPUTS
The U-150 is equipped with the following digital inputs: USB input, TOSLINK opti-
cal S/P-DIF inputs, and BNC electrical S/P-DIF inputs.
TOSLINK OPTICAL INPUT
The U-150 comes equipped with two optical S/P-DIF (32-96kHz, 16-24 bit)
TOSLINK inputs.
BNC DIGITAL INPUTS
The U-150 comes equipped with two electrical S/P-DIF (32-192kHz, 16-24 bit)
digital inputs.
USB INPUT
The U-150 comes equipped with one fully isolated, UAC 2, asynchronous USB
input. It supports 32-192kHz, 16-24 bit PCM and DSD64/DSD128 using DoP
encoding.
When connecting a computer running Mac OS X or Linux, no drivers are needed.
For Windows a driver can be downloaded from the Aavik Acoustics website.
Note: When playing music in PCM format from a computer, it is possible to select
sample rates as high as 384kHz. The PCM DAC in the U-150 however, only
supports sample rates up to 192kHz.
