The TT-Au comes with your choice of the following capsule options:
TT 12-Au: The GK12 Capsule is Brilliant, yet Smoother than the stock TT. Same capsule found in the popular Vienna II-Au.
TT 47-Au: The GK47 Capsule has Medium Mids with a softer top.
TT 49-Au: The GK49 Capsule features a very smooth, dark top, but a full mid and bottom end. Great for getting that extremely vintage vibe on would-be harsh sources. Perfect for strings.
TT 67-Au: The GK67 Capsule has a 60's vibe w. Slightly Mellow Tone and a little extra Mids. Same capsule found in the popular Hamburg 67-Au Microphone.
TT 251-Au: The GK251 Capsule is sweeter, top and bottom.
Which capsule should I choose? Glad you asked! Here are some test recordings we did comparing all 5 available TT-AU Models on 5 different sources:

Sebatron Thorax MkII Description
The New Sebatron THORAX is an evolution from previous models most notablely in Frequency Response, Dynamic Range , improvements over noise floor and compression characteristics.
Quality components and build make this Valve Microphone preamp and Compressor a must for any professional recording setup.
The Sebatron THORAX preamp is centered around the newly developed 'AXIS' preamp core. The THORAX/AXIS preamp core features are:
- Fully balanced and unbalanced inputs and outputs.
- Transformer coupled microphone input.
- High Impedence Direct Input for Guitar , Bass , Keyboards or line level signals etc.
- A variable 'pad/gain' control
- A passive 40Hz to 400Hz variable High Pass Filter
- 180 degree phase switch
- Phantom power
- Output level control
This controls a full thirty db swing and acts as a pad control when rotated
fully left and a gain control when fully set to the right. Everything from
close miced drums to gentle acoustic overheads can be handled and controlled
through the useage of this pre control.The Pad/Gain control is a dual feature
parameter that acts as a pad for dealing with heavy mic/line signals by
varying negative feedback between the input and the first valve triode stage
and by also controlling the interstage coupling level.The pad/gain control
provides just over 30db swing that allows the user to comfortablely deal
with heavy audio signals ( up to +10db ) with a very transperent reponse
but also able to drive a signal into mild to heavy distortion if required.This
means that anything from close miced drums to line level signals through
the Direct Input or Mic input can be delt with and processed by the AXIS/THORAX
preamp stage .
Variable Hi-Pass Filter:
Passive means that this stage doesn't have an active gain element which
means by switching this feature into the signal path , there will be no
added noise , distortion or colouration.This filter is useful on many sources
particularly voice or guitar to eliminate very low frequencies that will
subsequently eat into the dynamic range of the signal yet offer little or
no real musical value.Sometimes vocals will 'sit' better in a mix if the
lower frequencies roll off fairly high.Easy to put back in at mix time if
needed , but better eliminated earlier on rather than latter. The interplay
between the 'colour' and variable Hi-Pass can sometimes also provide interesting
creative textures to work with.
Output Level Control:
The Output level control provides up to another 30db of gain , however control is clean and transperent through the whole scale.From mic input to final output , the THORAX/AXIS preamp stage can provide up 70db of gain.
Valve Equalizer and Optical Compressor:
The THORAX Equalizer is intergrated into the optical compressor to preserve the integrity of the audio signals. This is the reason why the two components can't be accessed individually. The Equalizer is boost only and based around two primary bands , Deep and Air/Bright. The 'Deep' control peaks quite low at 80Hz but has a smooth 6db per octave rise however as this dial is increased so is a percievable 'enhancement' quality to the bottom register that seems to 'thicken' up the signal. Ideal for Bass , Guitars , Keyboards or Vocals where the original signal may be too thin or narrow to commit to proper recording. The Air/Bright is switchable from 10Khz ,12khz or 14Khz . These are delicate boost EQ controls that are designed to sweeten up the signal with little or no signal artifacts.
- Fully balanced and unbalanced phono and XLR inputs and outputs
- Switchable mic/line input
- Variable input trim control
- Fully variable and switchable Two band passive Equalizer
- Fully variable Threshold, Ratio, Attack, Release
- Tight/Smooth switch similar to Peak/RMS
- Switchable Side-chain insert for external EQ or 'Ducking'
- Variable High Pass Filter for compressor side-chain control
The Optical Compressor is a feedback design and therefore is also post EQ. Detection takes place after the EQ to increase the overall depth of the compression amount. The Compressor Detection circuitry has been optimized for fast , tight charactersics but also has significant flexibility to mimic some classic slower time curves of the past. The fully variable attack/release controls allow the user to easily fine tune the compression envelope and the Ratio control is invaluable for providing the gateway into compression that is neither heard nor unheard. At the far left setting , the ratio control operates at the minimum and careful alignment with the envelope can provide a compression characteristic similar to analog tape. Particular attention has been made to compression depth so signals can be subtley compressed or heavily slammed. The compression 'mode' is setup by the 'tight/smooth' control toggle. This is similar to Peak/RMS switching but a little more extreme and linked to envelope response.
Gain makeup is all valve and the interplay between the input trim control and output level control can create some interesting and organic textures to signals.
If injected from the AXIS end ( D.I input for example ) the signal can be driven up to the point of saturation via the use of all the four gain and output level controls.
The compressor stage features balanced and unbalanced inputs/outputs that can handle a wide range of levels from cold to hot.Two of these stages can be linked up via the side chain input on the back to form an accurate stereo buss compressor. Mixes can be processed in an organic manner when run through the THORAX circuitry
even with no EQ or compression.
