The 5051 from TL Audio is a single channel voice and instrument processor with microphone, line and instrument inputs, a compressor, a four band equalizer and a noise gate. Housed in a 2U rack chassis, the single illuminated VU meter monitors the input level, output level or the compressor gain reduction.
Part of the Ivory 2 Series, the unit is a hybrid valve signal processor, which utilize low noise solid state electronics in conjunction with classic valve circuitry to produce an audio processing unit that offers a high quality signal path with a unique tube audio character.
Microphone and line inputs are provided on electronically balanced XLR connectors and the line input is duplicated on an unbalanced 1/4" TS phone connector.
A solid state, electronically balanced input amplifier is used to achieve very low noise, low distortion and wide bandwidth performance. An ECC83/12AX7A triode valve stage, run from a stabilized 150v DC supply, is used as a second stage voltage amplifier to obtain the classic vacuum tube sound and gradual overdrive characteristics.
Phantom power and a 30dB pad are provided on the microphone preamp stage along with a switchable 90Hz high pass filter.
A front panel instrument input is provided, thus allowing guitars, basses and keyboards to feed directly into the unit, removing the need for a separate DI box.
Balanced and unbalanced line outputs are provided on XLR and 1/4" TS phone connectors that can be used simultaneously.
A single illuminated VU meter monitors the input level, output level or the
compressor gain reduction.
Offers variable control of threshold and ratio, with switchable attack and release times and a choice of soft or hard knee compression modes.
A "Hold" facility reduces LF distortion, and a side chain insert point is provided for frequency conscious compression.
An independent gain make-up control is provided, to retain the subjective loudness of a compressed signal, plus an overall master output level control.
The output control has a nominal 0dB of gain at its centre, with up to 15dB of further gain available to achieve the high level required for some digital recorders.
Four band valve EQ with a triode valve stage in each filter
Up to 12dB of cut or boost and a choice of four pre-selected frequencies on each band.
An "EQ PRE" switch places the EQ ahead of the compressor in the signal path.
Simple but effective noise gate with variable threshold to remove unwanted background noise.
