WARNING: the digital inputs accept up to 192 kHz / 24 bit stereo PCM signals. So DOLBY DIGITAL (AC3) multi-channel signals coming from audio/video sources (such as the audio of a film in DVD) or DTS can not be reproduced. The output of these devices will therefore be set in STEREO mode for the signal to be reproduced.
*Remark: when performing the installation of fiber optic cables, the minimum bending radius should be 40 mm. A bending with higher radius value may cause the cable to break and the consequent disruption of the digital signal.
OPTICAL 1/OPTICAL 2 inputs selection
1. Through the DRC MP, selecting the OPTICAL 1 / OPTICAL 2 input.
2. Through the OPTICAL 1 SEL / OPTICAL 2 SEL terminal properly set up (see section 4.3.4).
This control is activated by connecting the terminal at + 12V.
3. Through the selection of the OPTICAL 1/ OPTICAL 2 input via the bit One HD Virtuoso PC software.
4. Through the selection of the OPTICAL 1/ OPTICAL 2 input on the OEM source, using the “Auto Input Switch” function, via the bit One HD Virtuoso PC software (see section 5.6.1 - 7.2.4).
5.6.1. OPTICAL 1 / OPTICAL 2 AUDIO DETECT.
By activating the ”Optical 1 / Optical 2 Audio INPUT SWITCH” function from the PC software, it is possible to automatically activate the OPTICAL 1 o Optical 2 input of the bit One HD Virtuoso, whenever an audio signal is present. Activate the function using the menu as described in section see section 8.3.6.
*Connect the OPTICAL 1 or OPTICAL 2 input of the bit One HD Virtuoso to the digital audio source as follows. The Audio Detect function is available on one input at a time.
WARNING: the activation of the "Auto Input Switch" function, and the related selection of the auxiliary input to be used, leads to the loss of the other two auxiliary inputs not selected.
Remark: by activating the “Optical 1 / OPTICAL 2 Audio INPUT SWITCH” function, this will have priority over the other inputs of the bit one HD Virtuoso. Switching will take place when the audio signal is available on the OPTICAL 1 or OPTICAL 2 input. In this operating mode it is possible to control the volume trough DRC MP volume, or directly from the digital source connected to the optical input selected.
The usability of the Optical 1 / Optical 2 inputs AUDIO DETECT depends on the use of the same inputs for other functions (see section 8.3.6).
5.6.2. OPTICAL 2 / SDC DETECT + B-CON
By connecting the optical output of the B-CON to the Optical 2 input of the bit One HD Virtuoso, it is possible to automatically switch the Optical input by using the connection between the SDC connector towards and the B-CON. When Bluetooth audio streaming starts, the B-CON device will automatically activate the Optical 2 input. In case of incoming calls via Bluetooth hands-free telephone or Bluetooth audio end streaming, the main Master input will be reactivated.
This function, if enabled on the B-CON device, will allow you to adjust the main volume not only with the DRC MP, but also with the volume keys of the connected mobile device. If the Absolute volume function is not enabled on the B-Con it will be possible to adjust the main volume only with the DRC MP.
5.6.3. “AUTO INPUT SWITCH RVA” OPTICAL 1 / OPTICAL 2 SIGNALS.
Activate the ”AUTO INPUT SWITCH” function on the OPTICAL 1 or OPTICAL 2 input via PC software to enable the bit One HD Virtuoso OPTICAL 1 / OPTICAL 2 input, each time the source AUX input is activated. When using this function the bit One HD Virtuoso volume can be controlled through the source volume (see section 7.2.4 - 8.3.5).
Connect the bit One HD Virtuoso OPTICAL 1, OPTICAL 2 input to the audio source and the processor’s RVA input to the Master source AUX input (Head Unit).
WARNING: the “Auto Input Switch” function activation, and the subsequent selection of the auxiliary input to be used, may cause the loss of the other two auxiliary inputs not selected.
Remark: when activating the “Auto Input Switch” function, the DRC/PC Software can no longer be used for the switch of the audio system inputs. The switch can be enabled through the audio system source, selecting the AUX or Master input. When the “AIS - Auto Input Switch” function is active and a bit Play HD is connected to the system along with Full DA amplifiers (AD LINK - AC LINK) the DRC MP will be disabled and will display the following: “DRC DISABLED”.
Connect the Head Unit AUX input to the RVA connector of the bit One HD Virtuoso as follows, using the wiring supplied in the giftbox. The selection of the source AUX input will then allow the automatic selection of the bit One HD Virtuoso auxiliary input.
*If the car HEAD UNIT does not feature an AUX analog input, connect the USB RVA device, supplied with the product, to the USB player of your audio source as shown to the side. The USB device contains the ready-to-use 16.5KHz.MP3 format file (default), but it is possible to choose one of the other tones included in the compressed folder during the calibration (see section 8.3.5). If a USB reader is not available, you can copy the tone to be used for automatic switching from the supplied USB RVA device to an SD Card type storage device. Please note that the storage device must contain only this file and no other files. If you use the USB memory to activate the switching via the RVA function, just select the USB (SD) input of the main source (Head Unit).
