Hardware Installation Place the Cello on a flat surface in front of your computer screen. You will need to be able to easily access the unit and will find that some controls require more frequent adjustment depending on the way you work. Most of the controls that you will regularly need to adjust are available on the hardware panel but you will also want to be able to easily access the additional controls available through the JoeCoControl application on the computer.
Operating modes There are 4 modes of operation of the Cello: All channels at up to 48kHz sampling 16 channels at up to 96kHz sampling 8 channels at up to 192kHz sampling 4 channels at up to 384kHz sampling All modes support the lower sample rates available in the higher channel count settings. Select the operating mode using the blue button at the bottom left of the Mic/Line Input Controls section.
Alerts Beside the orange arrow button is the alert indicator. This shows green when there are no Alerts but changes to Red when you need to be alerted to a clocking error. If there have been alerts that have since been resolved it will change to brown. Pressing the Alert button brings up a dialogue box which shows you the exact nature of the error condition so that you can resolve it. If the error has since been resolved the dialogue will change colour to reflect the current situation.
Top+: adds a subtle high frequency lift to the mic channel. The turnover frequency can be adjusted using the “+” button beneath or on the hardware interface by pressing and turning the headphone 1 knob (or headphone 2 knob for channel 2) Note that there is no onscreen level control on the Mic Pre and Instrument inputs. The level control on these channels is via the physical control knob on the hardware interface. This allows for a fully analogue signal path through these most sensitive circuits.
Digital Output: selects what to output on the digital output RCA connector Word clock SPDIF ADC setup select between the ADC input filter modes to your taste. In 384kHz mode, an additional option allows you to cancel out any residual DC level for highest fidelity DAC setup selects between the DAC output filter modes to taste Mode select – selects the operating mode as described above.
There are 4 stereo stems (2 stereo at the highest sample rates) which are returns from your workstation to allow you to separately control the relative levels for example of the backing tracks and vocals for different performers in their headphones. Each channel offers: level fader, pan, Mute, Solo and PFL (Pre Fade Listen) controls To select a different mix, click one of the grey buttons to the left of the orange arrow in the small panel low latency mixer panel.
MUTE – mutes the monitors The faders control the master level fed to each of the outputs. For example pulling down the ph-1 fader will reduce the overall volume in headphone 1 output. AFL – After fade listen buttons will reflect the respective mix onto the main monitor outputs The Monitor section also includes buttons for monitoring: Stereo, Mono, Left, Right, Reverse which are hopefully self explanatory.
particular requirement for their headphone mix that you want to be able to recall quickly later. You can give each mix an easy to remember name to make life easier but the program will give it a default name with the date and time if you wish e.g. Main Mix 18-07-17 17-18-26.jcx To recall a mix just select the mix you want to recall and load it.
