One-Zero-Two Line Level Pre-Amplifier
Holton One-Zero-One Line Level Pre-Amplifier
Is a fully discrete two channel line level pre-amplifier featuring full Class A power MOSFET output stage.
Each channel has its own discrete low noise voltage regulator with a common PI filtered raw DC supply.
This pre-amplifier is capable of up to 5 watts RMS output into 8 ohms, so it is capable of driving with ease 4 x sets of 32 ohm headphone on each channel continuously.
The pre-amp comes with 2 x headphone outlets on the back, which can be expanded to 4 x outlets if so desired.
So it not only a high end line level pre-amp, it can be the bases for a very high quality multi outlet headphone amplifier.
The current version can be supplied with either dual 48 stepped attenuator volume controls or a single 48 stepped stereo attenuator.
