INTRODUCTION Whether you have a Headbone VT or a Headbone SS, the setups and connections are identical. For simplicity , this manual will discuss the Headbone VT . It is important to note that because of the very different nature of solid-state amps and valve-tube amps, each Headbone’s internal circuit is different. The Headbone VT is exclusively[...]

True to the Music Radial Engineering Headbone Owner ’ s Manual Why is this setup so cool? Because it truly covers all of the bases: the powerful clean sound from a 100-W att amp is radically different than an all-tube 30-W att amp cranked to 10. Not just as far as loudness goes, but also as far as tone. Being able to use that reserve power for bl[...]

Input Buffered – This is the primary input for your guitar and pedal effects that do not buf fer (pre-amplify) the signal. 2. Input Direct – Used when driving the Headbone from a device, like the Radial Loopbone, that buffers (pre-amplifies) the signal. 3. T o Amp[...]

True to the Music Radial Engineering Headbone Owner ’ s Manual ance. Y ou must manage the speaker connections for the best impedance match. It is important to note that most amplifiers are designed to work best at their rated impedance. If your amp features selectab le impedance loads, use the one that matches your speaker cabinet. A lways consu[...]

True to the Music Radial Engineering Headbone Owner ’ s Manual 10 from electrical shock. Most amplifiers have been subjecte d to safety tests from authorities like UL or CSA. Amplifiers that have passed these tests are safe to use with your Headbone. If you intend to use the Headbone with amps that only have 2-prong AC plugs, such as old vintag[...]

True to the Music Radial Engineering Headbone Owner ’ s Manual 11 F AQ Q: I heard that tube amps must always see a speaker load or else they will blow up. Is this true? A: This is true. T o deal with this, the Headbone is equipped to manage two loads: the speaker for the active amp and a load resistor for the standby amp. The Headbone transitions[...]

True to the Music Radial Engineering Headbone Owner ’ s Manual 12 amps and speaker can I be? A: As a general rule, we do not recommend running cables any more than 20 feet as you are subjecting the signal to increased resistance. If you are intent on doing so, use good quality cables. For speaker con- nections use large gauge (12A WG) speaker cab[...]
