14 INSERT
This stereo jack socket allows you to connect external devices, such as a compressor or
EQ, for dynamic signal processing.
For connection, use a "Y" cable with a TRS stereo connector wired as follows:
tip (T) - send, ring (R) - return, sleeve (S) - common ground, then connect the external
device using two unbalanced connectors, one for the input and one for the output.
15 DC INPUT
Connect here the external power supply unit supplied with preamp.

RECOMMENDATIONS FOR USE

We recommend that the preamp is positioned on a flat surface in a well-ventilated room,
making sure that the valve cooling slots are unobstructed and not in contact with any
surfaces. Before connecting the power supply cable to the power input socket, turn the
Input and Out knobs to -∞ and check that +48V phantom power is switched off. Power
on the preamp and then connect the microphone or instrument cable to the Input socket.
Adjust the Input and Out knobs so that the CLIP LED on the VU meter lights up with very
loud signals. The central preset selector allows you to control the level of tube saturation
to colour the sound of the input source. You can choose from 16 different settings divided
into the following:
COLD - to retain the natural sound of the input instrument/voice. Almost linear response
without any significant tonal colouration.
WARM - to emphasize the presence of the input instrument/voice. Response with enhanced,
more incisive loudness.
WARM + GAIN REDUCTION - For situations where the input signal is very loud and close to
distortion (effect of proximity or very rapid changes in signal amplitude). Response similar
to WARM presets.
COLD + GAIN REDUCTION - For situations where the input signal is very loud and close to
distortion (effect of proximity or very rapid changes in signal amplitude). Response similar
to COLD presets.
