The Chandler Limited TG2 Pre Amp/DI is a recreation of the rare EMI TG12428 pre amp used in EMI/Abbey Road recording and mastering consoles in the late 60s and early 70s. The sound was used on many famous recordings done at Abbey Road including The Beatles "Abbey Road" and Pink Floyd "Dark Side of the Moon."
This microphone pre-amplifier features the same discrete transformer balanced amplifiers as the TG series limiter and offers a creamy, smooth tone with a surprisingly open, clear top end. The sound, as explained by many users, has"warmth" and punch, but with a "beautiful" expanded top end. In fact, the unit does have a small rise in its top-end frequency response and some warmth inducing distortion, which contribute to its sound.
 
Stepped Output (Stereo) Option
All TG units require and function on the PSU-1, Chandler Limited power supply. The PSU-1 has an internal switch for setting voltage to 120V or 220V (115V/230V).*Please note:
 
Not all of the early Abbey Road TG2 Pre Amp/DI units have the "impedance" as a standard feature of the unit. If buying a used unit, please inquire as to whether the unit is equipped with the impedance before purchasing.
 
The Features
Input Gain Control
- Features a transformer-balanced input with 5–75dB of gain
Output
- Functioning as a console fader, this control is placed after the gain stage and before the output stage. This allows for trimming of the input signal between the 5dB steps on the input switch, as well as allowing the user to run the input very hot (for extra coloration) without distorting the recorder. In most cases this will be left in the full position
Direct In
- This is an unbalanced high impedance input for guitar, bass, samples etc. The switch bypasses the mic transformer and feeds directly to the amplifier. The naturally high impedance of the amp causes no loading. The DI switch on the front panel can also be used as a mute switch when using the rear panel mic input
Summing Option (on back panel) 
- The signal is mixed from both preamps and is sent to the output of the second channel. You can now bypass your console using great sounding discrete circuits and maintain a minimal signal path
Impedance
- This allows for switching the input from 1,200 ohm to 300 ohm values to match any mic
- Phase reverse
- 48-volt phantom power
- PSU-1 Power supply not included (sold separately).
