Government´s Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures: There are no user serviceable parts in this equipment. refer all servicing to qualified service personnel. Condensation can form on the inside of an amplifier if it is moved from a cold environment to a warmer location. [. . . ] To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation. All electrical and electronic products should be disposed of separately from the municipal waste stream via designated collection facilities appointed by the government or the local authorities. Thank you for purchasing this Blackstar HT-5 amplifier. Like all our products, this amp is the result of countless hours of painstaking Research and Development by our world-class design team. Based in Northampton (UK), the Blackstar team are all experienced musicians themselves and the sole aim of the development process is to provide guitarists with products which are the ultimate tools for self expression. All Blackstar products are subjected to extensive laboratory and road testing to ensure that they are truly uncompromising in terms of reliability, quality and above all TONE. If you like what you hear and want to find out more about the Blackstar range of products please visit our website at www. The HT-5 is the ultimate studio and practice amp, packing all the great tone and innovative features of the award-winning HT valve pedals into a two channel, footswitchable valve amp format. The patent-applied-for ISF (Infinite Shape Feature) circuit gives you infinite adjustment over the characteristics of the tone control network and takes you from the USA to the UK and any where in between. So now you can effectively design your own tone and finally find `the sound in your head'. In making the HT-5 ideally suited to home and studio use, the aim was to develop a valve amp which sounded full and toneful even at the lowest volume level. With this in mind the Blackstar design team designed a brand new valve power amplifier topology. The HT-5 power amplifier is a low powered push-pull design which produces the crunch and break-up characteristics of a traditional 100W output stage but at a much lower volume. This is achieved by the use of a 12BH7 dual triode in push-pull configuration producing 5 watts output, which is rich in valve harmonics and compression. The HT-5 also has a fully specified speaker emulated output which further enhances the studio credentials and allows any guitarist to get amazing valve tone straight to tape or disk, or through headphones. It also features the unique 4x12/1x12 voicing switch allowing you to change the tonal characteristics of the emulated signal between two emulated cabinet types. Add to this an effects loop with switchable level, along with 16 and 8 speaker outputs which allow you to run the amp into an external speaker cabinet of your choice, and you have everything you need for recording or practising. Always use a good quality screened guitar lead. When the LED is off the Clean Channel is in operation. Low settings, counter clockwise, will deliver a clean sound on the edge of break-up. As the Gain control is increased clockwise (CW) the sound will become more overdriven moving through crunch tones until, at its maximum position, a full distorted lead tone is arrived at. Bass The Bass control adjusts the amount of low end frequencies in your tone. [. . . ] The lead should only be connected to a power outlet that is compatible with the voltage, power and frequency requirements stated on the rear panel. If in doubt get advice from a qualified technician. The outputs marked `1x8 Ohm or 2x16 Ohm' are for the connection of either a single 8 Ohm extension cabinet or two 16 Ohm cabinets. Also, the internal loudspeaker of the HT-5 combo can be plugged in here if it is used with a 16 Ohm extension cabinet. [. . . ]
