Black Ice Audio ( Jolida ) F360 Vacuum Tube Preamplifier Valve With SSX - Rare in the UK!
Listed at £750 under list price. U.K. 230v version.
Condition is brand new, still sealed in the original box.
A very special tube preamplifier designed by Jim Fosgate with tone and dimension controls - has the SSX Sound Expander built in. Plus rear rca outputs.
Remote volume control.
When the SSX is switched to bypass, this preamp creates a perfect square wave (and uses no negative feedback).
Jim Fosgate uses an upgrade to the classic Cascode circuit design and adds a mosfet which gives the musical performance of tubes but with the speed and detail of current solid state designs.
So the design is a HYBRID - valve and solid state mix to fix issues of buffering the signal, controlling high and low frequencies, focusing or expanding a 3D image and rear outputs for the option of creating an analog surround system (or a false ambience to expand what can be perceived as the actual location of the recording). Using the hybrid design allowed Jim to get to the perfect square wave (with the EQ/tone controls off).
The 360 offers both XLR and RCA inputs and outputs as well as outputs for a mono or stereo subwoofer.
It also has a full tape loop for external components or a legacy tape deck.
And for those who want to go even further there is a set of outputs for rear stereo speakers (volume setting can be set and then controlled via the main volume pot).
Gain is 10dB
Max output voltage: 13V RMS front channels, 8.5V RMS back and sub channels.
