[. . . ] EX1200 User's Manual Version 1. 1 April 2001 ULTRABASS PRO www. behringer. com ENGLISH ULTRABASS PRO EX1200 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure--voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] The limiter limits the level of the newly generated bass signal to the adjusted value, the threshold control can be set within a range from 0 dB to "OFF" (limiter off). To prevent damage to your speakers the same safety margin with respect to the output level should be observed as with normal operation without the ULTRABASS PRO. INTRODUCTION + + 8 ULTRABASS PRO EX1200 GAIN REDUCTION meter. This meter indicates that the limiter has been put into operation and is controlling the gain reduction. In this case, it might be wise to reduce the bass level with the LEVEL control. With the correct settings it is possible to create a so-called loudness effect: At low volumes the ULTRABASS PRO creates additional harmonics and extends the range of the used system and at higher volumes the limiter limits the strain of the created subharmonics to free the maximum sound pressure level of the system. Satellite section The X-OVER function acts as a highpass filter in the stereo main path for use in combination with a subwoofer. The activated highpass filter prevents the main speakers (now operating in a multiway active system) from being overloaded by the generated low frequencies. If the X-OVER switch is set to SPLIT, all low-range frequencies below 70 Hz are filtered in the stereo main path, and the newly generated low frequencies are exclusively routed to the subwoofer via the subwoofer output. However, if the X-OVER function is switched to FULL RANGE, the generated subharmonics can be added to the original stereo signal by depressing the ULTRABASS switch. With the ULTRABASS switch the generated subharmonics can be led to the satellite loudspeakers. This is usefull to create a smooth transition from subwoofer to satellite, or if no subwoofer is used. This is the level control for the main speaker system in full range operation and for the satellites in split (x-over) operation. The level of added bass-frequencies present at the satellite output is not dependent on the setting of the SATELLITE LEVEL control. With these level meters the left and right output level of the ULTRABASS PRO can be monitored. As mentioned before the ULTRABASS PRO has several controls which influence the sound characteristics of the unit. The FREQUENCY, DYNAMIC PUNCH, SUBHARMONICS and BASS MODE controls change the sound of the ULTRABASS PRO. The other controls govern how much of the effect is audible and how the unit is connected. Please take the time to play around with the ULTRABASS PRO at home or "off line" to get the feel of the possibilities it offers. Please also note the instructions given in the "INSTALLATION" chapter. Please make sure that your local voltage matches the voltage indicated on the unit, before you attempt to connect and operate the ULTRABASS PRO. Blown fuses may only be replaced by fuses of the same type and rating.
