The card feeds the converted output signals of channels 1 and 2 to the SPDIF
phono output. The sample rate is switchable between either 44.1kHz or to 48kHz,
and the card can be clocked to an external digital source via the BNC wordclock
input. When clocking the DO-2 to an external source the sample rate setting on the
DO-2 needs to be set to match the external sample rate, otherwise correct locking
may not occur and audible clicking may appear on the digital output. In terms of
gain, the DO-2 will generate a signal level of 0dBfs in the digital domain when +18dBu
of output level is generated at the balanced line output of the 5052.
5. GETTING STARTED
5.1 Connections.
There are various ways that the 5052 can be connected into your audio system. The
four most common are:
a) As a vocal or instrument front end
b) Connected to a channel insert point on a mixing desk
c) Connected to a group or master insert point on a mixing desk
d) Connected in-line from the mixer’s master outputs to the 2-track recorder
To use the 5052 as a front end, connect the output of the 5052 directly to the line
(not mic) input of your console, recorder or sound card. A common mistake is to
plug the XLR line output into the XLR mic input of a console. This will cause the
console mic inputs to overload very easily and may result in a loss of quality. Once
the output is connected, simply feed your microphone into the rear panel XLR mic
input (with the +48V engaged if the mic is a condenser type), or feed your instrument
into the front panel jack input on the 5052. Recording direct to the multitrack
recorder (thus bypassing the console) is a common technique these days as it keeps
the signal path short, and of the highest quality. No unnecessary console stages are
passed through, thus maintaining quality.
Many mixers have sockets called ‘insert points’, which allow processors such as
dynamics devices and EQs to be patched in-line into the mixer signal path at various
points. The mixer’s channel insert point usually ‘sends’ the input signal out directly
after the mixer’s preamp stage - allowing connection to the line input of the 5052 -
and then returns the processed signal from the line output of the 5052 back into the
mixer at the same point in the signal path. This is commonly achieved using a special
insert cable (sometimes known as a ‘Y’ lead or split lead - usually a stereo 0.25” jack
