Video demo of the Rocktron Mainline 300 Watt Stereo power amplifier in BRIDGE mode. Using a popular DSP Preamp/Processor's stock presets this demo shows the uses and sound variations of the Mainline 300 tube emulation circuit by using adjustments to the Resonance and Presence Controls.
The Mainline is a solid state power amp with a new front end circuit that emulates that sought after tube "feel" found in classic tube amps.
With a LA Custom designed filtering in the front of the amplifier, the sweet spot in tube emulation has been achieved. The Mainline has a proprietary circuit that truly emulates the way a tube amp interacts with a speaker. Typical solid state power amps do not know or care what they are connected to, so they tend to always have a flat response. The Mainline amps possess an enhanced frequency response that is very much like a tube amp connected to a speaker. This adds a level of warmth and clarity not usually found in solid state power amps.
The Mainline Power Amplifier features additional circuitry providing an "instrument/line level" (INST/LINE) switch. The INST input allows you to run your pedals - or pedal board - directly into the amp without having to utilize a separate preamp. The LINE input allows use of a preamp in combination with the Mainline power amp, providing plenty of flexibility with the Mainline.
Rocktron has covered the bases in a great sounding, super responsive power amp. It's like having a "head" in a single rack space!
