Ausstattungsliste: Alpha Design Labs ADL GT40
- GT40 has no setting for gain to match different impedance headphones. We recommend using 16 ohm to 300 ohm impedance headphones.
- IMPORTANT NOTE FOR RECORDING:
- The TENOR chip used in the GT40 has a bandwidth limitation of 12Mbps (USB 2.0 full speed operation), and due to this limitation only one I2S input or output can be set for 24bit/96KHz application at one time. Therefore, under this condition, for simultaneous multiple-channel applications other I2S interfaces must be configured at 16-bit/48KHz or 16-bit/96KHz. In other words, when recording it is necessary to set the audio Input on the computer to 24bit/96KHz (PC-Sound application; MAC-MIDI application), but do not set not the audio Output to 24bit/96KHz. The Output should be set to a lower 16bit resolution until recording is done. Then when you want to playback your 24bit/96KHz files through the GT40 you need to reset the output to 24bit/96KHz and reset the input to a 16bit resolution.
