TL Audio 5052 - Manual (Page 29)

5.3 In Use - Stereo mixdown mode.
Now we’ll assume that the 5052 is connected via its line inputs/outputs to the
master insert points of a mixer (see ‘Connections’ section 5.1). Set the input
selector switches on both channels to ‘LINE’, and activate each of the 3
stereo mode switches (Comp, EQ and Limiter) so that channel 1 can be used
as the master for both L and R signals of the stereo mix. Note that only the
compressor, EQ and limiter controls work as masters - preamp and in/out
gain settings remain independent - see section 4.30.
1. The first stage is to set up the gains of the 5052. With the compressor, EQ
and limiter stages switched out, start with the 5052 input gains at minimum and
output gains at 0dB.
2. Gradually bring up the 5052 input gains until the Drive LED illuminates with
the chosen source material - this should also generate a healthy reading on
the 5052 VU (when set to ‘I/P’). Then switch to meter ‘O/P’ and check that
around 0VU is being produced, and adjust the 5052 output level controls if
necessary. To get the most benefit from the valve stages it’s normal to keep
the Drive LED glowing most of the time, with the Peak LED illuminating on
transient peaks only. For a cleaner sound you can back off the input gain
and thus reduce the drive to the valve stages, which will cause the Drive LED
to glow much less frequently.
Now follow steps 4 to 9 in section 5.2.
6. FREQUENTLY ASKED QUESTIONS (FAQ)
Q: What type of valves (tubes) are used in the 5052?
A: The 5052 employs 3 dual triode valves, and the type used are Sovtek ECC83
(12AX7WA). A dual triode valve is one that provides two independent valve
stages within one glass tube, so while the 5052 has three valves this actually
means it has six valve stages: one each in the preamp, compressor and EQ
sections, repeated for both channels.
You can in theory use any brand of 12AX7WA in the 5052, but you may find
subtle difference in audio quality (and price) between various brands. We
