User manual HUGHES & KETTNER ATS 120

[. . . ] However, tht traditional , passive three-band equalisation controls and the "Soft-Click" circuitry make it possible to reproduce the mild distortion characteristics of a vintage valve amplifier. The "Soft Click" circuit prevents hard-sounding, unattractive transistor distortion and provides pleasant, lightly distorted clean sounds at higher gain settings. (2) VOLUME : determines the volume of the CLEAN channel. At settings around 8 or 9, mildly distorted "clipped" rhyhm sounds can be produced from single coil pickups. [. . . ] (11) REVERB: controls the amount of tuned reverb for CLEAN, CRUNCH and LEAD. (12) FX-MIX: determines the relative volumes of the original sound and the signal from an external effects unit connected to the effects loop. DRY= only original signal; FX= only processed signal. Intermediate setting allow the proportions of original and processed signals to be balanced as desired. TIP: If no external unit is connected up, the FX-MIX control can be used in conjunction with the ATS STAGEBOARD (optional) to set up an alternative master volume setting. This can then be called up using the ATS Stageboard. PROGRAMMING A SECOND MASTER VOLUME SETTING: select the channel or channels for which you wish to program an alternative volume setting. This is done by turning the appropriate FX-SELECT switch or switches to the ON position (there are 3 located on the rear panel of the ATS 120). Set the desired volume level using the FX-MIX control. FX switch ON/OFF, you can now cycle between the two different master volume settings. (13) MASTER: controls the overall volume of the ATS 120. When switched on, the red LED arrow will be illuminated. (15) / (16) / (17) (18) (19) The rear panel on the ATS 120 (15) MAINS LEAD SOCKET point for connecting the euro mains lead included with your amplifier. (16) FUSE: safety holder for the mains fuse (AT 1250mA). The fuse holder can be removed by depressing its fixings on both sides. The fuse can then be changed. (17) VOLTAGE SELECTOR, 220-240 VOLTS: on all European models, the ATS 120 can be set to operate on either a 220 or 240 volt supply by rotating the insert incorporated in the fuse holder. The value visible in the fuse holder`s window is the one which is operative. Models for North America and Japan are equipped at the factory with different transformers which are pre-set to the appropriate mains voltage standards. (16) SPEAKERS: the ATS 120 has two sockets for connecting loudspeakers or cabinets. The combined impedance of all loudspeakers used must never be less than 4 Ohms!The loudspeaker fitted to the combo version has an 8 Ohms impedance. Any further speaker cabinet connected to it should have an impedance of either 8 or 16 Ohms. For the ATS 120 Head: if a single speaker cabinet is used, its impedance should be either 4 Ohms or 8 Ohms. When two cabinets are used, each one should have an impedance of either 8 or 16 Ohms. (19) HEADPHONES: socket for standard stereo headphones. The frequency response of the signal fed to the headphone socket is tailored to reproduce the characteristics of a typical guitar speaker.
