THD Hot Plates also feature a Line Out, which is adjustable by its own volume control giving it a wide range of applications. The Deep switch offers two distinct bass settings to help you fill out the bottom end, or reduce the bass in a cabinet with too much low end. The Bright switch gives you two different high frequency levels so you can compensate for an overly bright, or dull speaker cabinet. The Hot Plate is also the only attenuator offering a Bright switch and a Deep switch for tailoring your sound. The harder you play, the brighter it glows. A by-product of the noise reduction circuit is that it generates light as you play. We've designed a passive, single-ended noise reduction system which provides approximately 10 dB of broad band noise reduction without gating or pumping, and without affecting the tone of the amp. The THD Hot Plate is the only attenuator on the market with built-in noise reduction to reduce the hiss and hum between notes. The amp thinks the Hot Plate is a speaker, so the sound stays true even when you turn the volume down. To use one: connect the speaker output of the amp into the input of the Hot Plate, then connect the speaker cabinet to one of the two speaker outputs of the Hot Plate (doesn't matter which one). The THD Hot Plate is designed for use strictly with vacuum tube guitar amplifiers, and each version is optimized for a specific impedance (2, 2.7, 4, 8, or 16 ohms.) These inductive loads are frequency compensated, which means it will give you the best possible sound for that impedance speaker and amplifier combination. The THD Hot Plate is the first, and for now, the only attenuator that is frequency compensated. The Hot Plate compensates for this, working like the Loudness switch on a hi-fi. As the volume drops, your ear becomes more sensitive to the mid-range, and less so for highs and lows. Your ear perceives sounds differently at different volumes: the louder the sound, the more sensitive your ears are to highs and lows. It passes a small part of the power to the speaker.Ī THD Hot Plate is a tuned network of capacitors, resistors and inductors which adjusts the overall EQ as the volume is turned down to compensate for the human ear's frequency response. It 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. What is the THD Hotplate power attenuator?Ī power attenuator is a device placed between the speaker output and the speaker cabinet. Thus the need for the THD Hot Plate power attenuator. Since most of the mojo you experience when using a tube amplifier comes from having the output tubes delivering power in their 80%-90% output range, unless you have a plethora of guitar amplifiers suited for every occasion, you are very likely to experience much inconsistency when using this high power amplifier at small to mid sized venues. If you're a guy who only owns a 100 watt Marshall and you want to use it in a small club, chances are you won't make the club owner very happy, or you won't make yourself happy when it comes to getting the tone you love to hear from that amp. The THD Hot Plate power attenuator is the solution to the age old problem concerning volume levels in different sized venues. Shipping: This Item Qualifies For Free Shipping on orders over $99!
