If you choose to activate the Optical 1 input as the Master input of your source, and this does not have an output volume control, this operation is essential to be able to adjust the volume from your audio source. For connections, refer to section 5.4.3 - 5.6.1 of this manual and proceed as follows.
1. Auto Input Switch
The automatic volume control for the auxiliary source (Aux - Optical 1/2) can be activated through the Head Unit volume control, if it is provided with an AUX input
(see section 5.4.3, 5.6.1; 8.3.5 ). If the car HEAD UNIT does not feature an analog AUX input, connect the USB RVA device supplied with the product to the USB player of your audio source as shown in sections 5.4.3; 5.6.1. The USB device contains the ready-to-use 16.5KHz.MP3 (default) file, but it is possible to choose one of the other tones found 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).
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press SKIP to skip the procedure, or if you want to use the USB RVA device.
Follow the instructions listed below:
1) Use of the Head Unit AUX input:
- connect the Head Unit AUX IN inputs to the RVA connector of the bit One HD Virtuoso using the appropriate cable.
- select the source AUX IN input (Head Unit).
- set the source volume to the maximum undistorted level.
2) Use of the Head Unit USB input:
- Press NEXT and then adjust the RVA function settings as per section 8.3.5.
At the end of the procedure:
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
2. Selection of the speakers available in the system
Speakers can be selected just by clicking on them. If the left tweeter, left midrange or left woofer are selected, the software provides the ability to automatically activate also the right tweeter, right midrange or right woofer. Once the software is started, this choice will affect the dedicated crossover type.
E.g.: if on the rear system only the woofers are activated, the software will only show a low-pass or band-pass filter as available. If you want to use a coaxial system as rear channel, both tweeter and woofer need to be selected and then you need to specify that a passive crossover is connecting them, so the software will show a high-pass filter as available.
Window for the selection of the speakers available in the system
Remark: if you decided to use the FIR mode the bit One HD Virtuoso will avail of a maximum of 9 output channels to be enabled.
From this point onwards a simulation of a system with the following components will be used:
- 3-way Front active
- 2-way Rear active
- 2-way center passive
- Stereo Sub
All 13 output channels of the bit One HD Virtuoso in IIR mode will be used.
- Press BACK to go back to the previous step.
- Press NEXT to go ahead with the configuration.
- Press CANCEL to exit.
Remark: Audio systems with at least 4-way front or 3 Rear are not fully compatible with AV bit In and bit Tune.
3. Selection of passive crossovers for speaker groups.
The presence of passive crossovers managing speaker functional groups in complex systems can be provided by the user.
E.g.: the 3-way Front can be managed as:
- multi-amplified (6 output channels would be required);
- passive mid-high speakers + separately amplified woofer (4 output channels would be required);
- 3-way passive (2 output channels would be required).
While performing the setup, the software will automatically notify the return within the 8 output channel limit, the warning message will then disappear and the NEXT button will appear.
- Press BACK to go back to the previous step.
- Press NEXT to continue the configuration.
- Press CANCEL to exit.
4. Processor outputs (Ch1÷Ch13 IIR MODE) allocation.
The bit One HD Virtuoso features 13 output channels. On this specific step of the procedure, any signal can be assigned to each output channel.
Eg.: the outputs 1 and 2 can be assigned to the rear channels simply to avoid having to lengthen the cables going to the specific amplifier.
For a matter of convenience, if the output 1 is assigned to the left woofers, the software will automatically assign the output 2 to the right woofers. If during the procedure the output 1 is assigned also to the left mid-high speakers, the software will show a warning message. Change the allocation of one of the two numbers marked in red and the software will automatically select the first available channel.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
5. Selection of the amplifiers connected through the AD Link / AC Link connection system.
If the system features amplifiers provided with the AD Link digital input and you want to connect them to the system, you need to select them on this setup procedure window.
The CH1-CH8 output channels will be available on the AD LINK 1 socket, while the CH9-CH13 channels will be available on the AD LINK 2 socket.
Remark: remember to assign the corresponding Amp ID to the specific amplifier. The bit One HD Virtuoso will automatically recognize the identified amplifier.
6. System configuration successfully completed.
Stop playing the Test track, remove the supplied Setup CD from the head unit CD player and then press OK.
