OPTICAL INPUTS & OUTPUTS
EVO 16 features two optical inputs and two optical outputs. Each of these
can be set to operate using optical stereo S/PDIF or 8-channel ADAT using
the EVO Software Mixer. All i/o will operate at up to 96kHz, with ADAT dropping
to 4 channels at sample rates of 88.2kHz or higher.
Running in S/PDIF mode, the optical i/o provides the option to integrate
external digital outboard, allowing up to 4 channels of audio in and out of
the EVO 16 at sample rates up to 96KHz.
Running in ADAT mode, the optical i/o provides a great way to expand to 24
inputs for recording via an external mic preamps such as the Audient ASP800.
The ADAT outputs could also be connected to headphone distribution systems
such as a HearbackTM system or to an 8-channel DAC for summing purposes.
When using higher sample rates such as 88.2kHz and 96kHz, you are restricted
to a total of 8 digital inputs and 8 digital outputs due to the limitations of the
ADAT protocol.
The EVO 16 includes a BNC Word Clock output which allows you to clock multiple
digital devices to the EVO 16’s master clock and keep everything in sync.
The Word Clock output will send a clock signal at the same sample rate (44.1,
48, 88.2 or 96kHz) that the EVO 16 is operating at. This will occur regardless of
whether the EVO 16 is being clocked internally or externally.
In a digital setup, there can be a number of options when determining which
device should be your master clock. Quite often the best device to set as the
master is the one that is connected to the computer such as an audio interface.
This way, when you open a project in a DAW, the audio interface should change
automatically to match the project sample rate, and therefore change the
sample rate of all the slave devices. However this depends on the devices being
used.
When connecting external digital devices to the EVO 16, it’s important to ensure
that all devices are synchronised.
To ensure this, one device in the setup must be set as the master clock. The other
devices will then use the master clock signal to stay in sync. There can only ever
be one masterclock present in a chain.
The master clock signal can be sent either via an optical cable embedded into
the digital signal data, or through a BNC clock line cable. Please bear in mind
that the clock will only travel in one direction through these connections, from
a device’s output to a device’s input.
