adjusted, use the Output Level control to set the overall output level of the
5050.
4.17 Compressor
On.
This switch enables or disables the compressor stage, thus allowing an A/B
comparison to be made between the original untreated signal and the
compressed signal. Any gain make up applied to the signal only becomes
active when the “Compressor On” is enabled. An associated status LED
indicates when the compressor is active. The Gain Reduction bargraph meter
will monitor the level of compression regardless of the compressor stage being
active or non active.
4.18 Output
Level.
The master level control is an output fader, which enables the 5050 output to
be matched to the following equipment. The control is calibrated for 0dB at its
centre, with a further 15dB of gain available by turning the knob fully
clockwise. The additional gain may be useful if the output of the 5050 is
connected directly to a digital recorder, which 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.
4.19 Bargraph
Meters.
The 5050 is equipped with twin 8 segment LED bargraph meters.
The output (right-hand) meter monitors the audio output from the unit. It has a
peak reading characteristic, with fast attack and slower decay.
The left-hand meter indicates the gain reduction occurring at the compression
stage. It will give a continuous reading, even if the compressor is bypassed. It
should be noted that the gain reduction indication is most useful as a measure
of the compression of the signal, and therefore does not include
the effect of any gain make-up that may be applied.
4.20 Optional DO-2 Digital Output Card.
The 5050 is designed to accept the optional D0-2 24 bit digital A to D
converter card, to allow easy interfacing with devices such as sound cards and
digital recorders. The card feeds the converted 5050 analogue output to the
DO-2’s SPDIF phono output. The sample rate is switchable between either
