User manual HUGHES & KETTNER ATS 120

[. . . ] The "Soft Click" circuit prevents hard-sounding, unattractive transistor distortion and provides pleasant, lightly distorted clean sounds at higher gain settings. At settings around 8 or 9, mildly distorted "clipped" rhyhm sounds can be produced from single coil pickups. Higher output pickups will produce a similar effect at a correspondingly lower setting. (3) BASS, MID, TREBLE : the CLEAN channel`s three tone controls can be used to generate a wide variety of different clean sounds. [. . . ] The quality of a reverb unit depends largely on the length and number of springs used; this genuine Accutronics unit generates a warm, realistic effect for the ATS 120 by having three particularly long springs. Increasing the degree of distortion on an overdriven sound will tend to make it more sensitive to reverb; in other words, too much reverb can easily swamp the sound. For this reason, the reverb effect is differently tuned for each of the three channels. When you change channels, you will not need to alter the reverb setting to achieve a similar-sounding effect. (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. 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). 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. 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!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.

ATS 120 Sound Examples The examples shown here are only intended as general illustrations, because they are strongly affected by the instrument used and your individual playing style. However, these settings will give you an initial overview of the range which the ATS 120 is capable of producing. [. . . ]
