You may find that some digital recorders require a good deal of input level in

order to register a 0dB reading on their meters (a +18dBu analogue output

usually matches 0dBFS in the digital scale). This is normal, since many digital

recorders are designed to preserve headroom and keep the signal well below

the 0dB clip point - thus preventing the recorder distorting. The 5021 provides

a further 20dB of gain at the output fader to drive digital recorders. It is

important to distinguish the difference between the output gain knob and the

gain make-up knob in the compressor section. The gain make-up control is

only active when the compressor is switched on. The output gain control is

always active but will have no effect on the compression characteristics of the

signal.

4.17 Optional DO-2 Digital Output Card

The 5021 is designed to accept the optional D0-2 24 bit digital A to D

converter card to allow easy interfacing of the 5021 with devices such as

sound cards and digital recorders. 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 5021.

5. GETTING STARTED

5.1 Connections.

There are various ways that the 5021 can be connected into your audio

system. The four most common are:

As an instrument front end

Connected to a channel insert point on a mixing desk

Connected to a group or master insert point on a mixing desk

Connected in-line from the mixer’s master outputs to the 2-track recorder

To use the 5021 as an instrument front end, connect the output of the 5021

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. The 5021’s balanced line outputs are the

recommended connections to use for the best sound quality. Once the output

is connected, simply feed your instrument into the front panel jack input on the
