The whirlwind qbox audio line tester/cable tester/test tone generator is the all-in-one audio line tester ideal for applications such as live sound, maintenance, installation work – anywhere audio runs down a cable. the qbox includes a microphone, a speaker, a test tone generator, outputs for standard headphones, a 1/4" jack for line-in or a 2k ohm (telephone) earpiece out. a handy clip attaches the qbox to your belt or equipment rack. simply generate into or listen to audio at any point in your system from the mics to the power amps to quickly confirm which sections are working and which ones aren't. the qbox can quick-check dynamic mics and cables without firing up the entire system. use the built in mic or tone generator at three different levels for activating a signal path or identifying a specific cable in a pile of cable ends. powered by a single standard 9v alkaline battery and housed in rugged abs, the qbox is light yet able to withstand the wear and tear of fieldwork. for an instant hands-free intercom, just plug in headphones and hook up one qbox on each end of a line and use the built-in microphone. use it to monitor a standard 3-wire intercom feed – leds confirm the presence of intercom or phantom power. use it as a squawk box to the stage from the main audio console during set-up. works in a pinch as a handy, portable, powered monitor too. the source section of the qbox lets you send a tone or the signal from the built-in condenser mic at mic or line levels. the speaker volume control lets you confirm incoming signals at mic or line level. a handy monitor switch allows the user to listen to a balanced signal or to two separate unbalanced signals on pin 2 or 3 (referenced to pin 1), such as a two-channel intercom. a split switch disconnects the two xlrs from each other so tone or internal mic can be sent out of one xlr while you listen to what's coming back on the other.

Volume 1 of the most complete and practical modern reference on tube guitar amplifiers – the first three chapters of this unique book cover introductory topics such as basic electronic circuits and passive components (resistors, capacitors, inductors), the building blocks of tube amplifiers. audio amplifiers are also investigated as "black boxes", from the outside perspective, and important concepts such as spectra, gain, bandwidth and distortion are introduced. – chapters four to six explain operational principles behind vacuum tubes (diodes, triodes, tetrodes and pentodes), and their use as rectifiers and active amplification components in guitar amps. – the rest of the book progresses through various stages of guitar amps, from input circuits and preamplifier stages, through tone control circuits and analog effects, to output or power stages. – after the in-depth coverage of tube power supplies, single-ended output stages (triode, pentode and "ultralinear") are covered first, followed by phase inverters and push-pull circuits. the associated controls such as "presence", "resonance" and "texture" are also discussed, using peavey valve – king 212 amp as a case study. – despite claims by their manufacturers, many modern guitar amps aren't "all tube" at all, but hybrid designs. most have a single tube in preamp stages to "color" the sound, and a cheap solid state output stage (usually using integrated circuits). others take the opposite approach, choosing semiconductor preamp stages and a tubed power stage. for that reason solid state (semiconductor) components and amplifiers are covered here briefly, together with two examples of hybrid amps. – this practical diy manual is richly and professionally illustrated with photographs of tubes, components and amplifiers, circuit diagrams, tube pinouts, curves and loadlines, graphs and charts. these valuable illustrations make it faster and easier to comprehend issues, a picture is truly worth a thousand words! all the information required to design and build tube guitar amplifiers is compiled in one place. – who is this book for? -guitar players wanting to learn how tubes and tube amplifiers work.- diy constructors who want to build, service or modify tube guitar amps.- buyers and sellers of tube guitar amps who need a better understanding of tube technology.- electronic technicians and engineers familiar with solid state devices and amps, who want to expand their knowledge of tubes and their circuits.- anyone who wants to learn how to design, build, test, fix, or upgrade tube guitar amps.
