Lexicon Signature 284
Designed by tube guru John McIntyre, the Signature 284 delivers sinuous touch and gorgeous tone as only a fully-cranked all-tube amp can. Its low-power design makes it ideal for recording as well as live performance applications where high volume levels are undesirable. The Signature 284's unique design combines a high-gain preamp with a low-wattage, stereo Class A power amplifier.
The preamp section uses three 12AX7 tubes and incorporates a switchable high-gain stage and beautifully voiced tone controls. To put the finishing touch on the 284's tone, a stereo power amp uses 2 EL84 tubes in a Class A configuration. A tube-driven stereo effects loop lets you place stereo effects in-line between the pre-amp and power amp for sonic effects that can't be obtained at the console. Simultaneous outputs let the amp drive any combination of stereo speaker, balanced recording, and slave amp outputs. The speaker outputs can handle 8 or 4 ohm cabinets. Built-in speaker simulation lets you select "smooth" or "bright" independently for each recording output. For silent recording, the passive load is automatically connected when the speaker is disconnected. Because the slave outputs tap the signal after the power amp, they carry all of the Signature 284's characteristic tone and can be connected to any power amp and gui-tar cabinets for greater performance volume.

Features:
* The ultimate solution to recording great guitar tracks in your project studio
* Delivers the authentic feel and tone of a fully cranked all tube amp
* Low power design and balanced recording outputs makes it ideal for recording or performance situations when you need to go direct
* Unique design combines a high gain preamp with low wattage, Class A stereo power amp
* Preamp tubes: 3 x 12AX7
P* ower amp tubes: 2 x EL 84
* Fan-cooled, 2U rack
T* ube-driven stereo effects loop
* Left and Right speaker outputs can handle any combination of 4 or 8 ohm guitar cabinets
* Speaker outputs have built-in passive loads for silent recording
* Stereo slave amp and recording outputs are post power amp — so they carry the sonic signature of the whole amp, not just the preamp
* Balanced recording outputs have speaker simulation built in — no need to mic cabinets
* Choice of bright (10 in.) and smooth (12 in.) speaker simulation for Left and Right recording outputs
* Recording great guitar tracks has never been simpler. Plug the guitar into the Signature 284, and plug the 284 directly into your mixer.
