THD Hot Plate Amp Attenuator - 8 Ohms. For sale is a Hot Plate guitar amplifier attenuator from THD.
These allow playing your amp at stage volumes, yet cutting the power down to moderate levels for recording, practice, small venues or domestic settings. The Hot Plate comes in a variety of impedance levels to match up to the output (load) impedance of your tube amp. These hot plate attenuators have been display/demo items, and are basically new. The THD Hot Plate Attenuator is a power attenuator and noise reducer that lets you attain the incredible sound of your amp running at high output and full distortion but at recording, small club, and neighbor-friendly volumes.It also makes a perfect dummy load. A power attenuator is simply a device placed between the speaker output and the speaker cabinet. The Hot Plate acts like a huge master volume control and permits the amp to be turned up most or all the way while absorbing most of the power generated by the amplifier and turning this power into heat.
It passes a small part of the power to the speaker. Designed for use strictly with vacuum tube guitar amplifiers, each version of the Hot Plate is optimized for a specific impedance. These inductive loads are frequency-compensated, which means you get the best possible sound for that impedance speaker and amplifier combination. Controls for attenuation levels of 0, -4, -8, -12, and -16 decibels. A setting for Load that acts as a dummy-reactive load.Switches on the front panel (Bright and Deep) help tailor the sound. Built-in bulb that works as a passive noise reduction system. Line level output with dedicated volume control on rear. Independent level control for the -16dB range.
Self-powered fans that operate automatically when cooling is needed.
