frequency control. This can be effective for “warming up” the low frequencies
or adding brightness or “air” to the top end frequencies.
4.10 Fat Contour Switch.
Each channel of the 5013 has a “FAT” contour switch positioned to the far
right of the unit, indicated by a red LED. The Fat switch adds a subtle boost to
the low end and high end frequencies with a slight mid range dip - meaning
the overall volume is not altered. The effect of this is to “sweeten” the signal in
a similar manner to the “boom and fizz” effect of many Hi-Fi speakers. The Fat
switch can be used on any signal or to “fatten-up” an entire mix, and may be
used in conjunction with the rest of the EQ controls.
4.11 Output
Level.
The output level control is centre-detented for 0dB gain, with +/-20dB of gain
available. The additional gain may be useful if the output of the equaliser is
connected directly to a digital recorder that requires a high level of modulation.
Note that applying additional gain at the output will not increase the dynamic
range of the signal, but will increase the noise level as well as the audio signal
being recorded, and should therefore only be used if an output level in excess
of the nominal +4dBu is required.
4.12 Optional DO-2 Digital Output Card.
The 5013 is designed to accept the optional D0-2 24 bit digital A to D
converter card to allow easy interfacing of the 5013 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 5013.
5. GETTING
STARTED
Having connected the 5013 checking that the operating level switch is at the
most suitable setting (see section 3.2), it’s time to put it into action! Here’s a
simple step-by-step guide:
1. The first stage is to set up the gains of the unit. With the EQ section
switched out, start with the input and output gains at 0dB.
