TL Audio 5052 - Manual (Page 4)

contribute to the smooth, open sound of the unit, along with a triode valve stage
that forms part of the gain make-up circuit.
A four band valve EQ stage is included, providing up to 15dB of cut or boost on
each band. The LF and HF bands provide swept frequency controls with a choice of
shelving or peaking response. The LM and HM bands are fully parametric with
variable control of gain, frequency and bandwidth. The ‘EQ PRE’ switch places the
EQ ahead of the compressor in the signal path, while the ‘EQ S/C’ switch places the
EQ entirely in the compressor sidechain circuit, for frequency conscious
compression. A triode valve stage is located just after the four EQ filter stages.
A peak output limiter is included, and this is located after the output level control.
This limiter has a high ratio and a fast attack time, making it ideal for prevention of
overload in digital recorders. A threshold control is provided, along with an LED
indication of when the limiter threshold is exceeded.
Mic and line inputs are provided on electronically balanced XLR connectors, and the
line input is duplicated on an unbalanced mono 0.25” jack connector. Balanced and
unbalanced line outputs are provided (on XLR and jack respectively) and these can
be used simultaneously. The operating level of the line input can be shifted from -
10dB to +4dB (unbalanced) or +4dB to +18dB (balanced) via a rear panel switch,
allowing the 5051 to accept very high levels - such as those from a digital recorder. A
pair of high impedance front panel instrument inputs are also provided, thus allowing
guitars, basses and keyboards to feed directly into the 5052, removing the need for
a separate DI box. Finally, balanced insert points (located after the preamp stage
but before the processing stages) and compressor sidechain insert points are
featured. The former allows other external units to be patched into the 5052 signal
path, while the latter permits frequency conscious compression to be performed by
patching in an external equaliser.
Please read this manual fully before installing or operating the 5052.
