User manual ALLEN & HEATH XONE 92

[. . . ] USER GUIDE Publication AP5345 Limited One Year Warranty This product has been manufactured in the UK by ALLEN & HEATH and is warranted to be free from defects in materials or workmanship for period of one year from the date of purchase by the original owner. To ensure a high level of performance and reliability for which this equipment has been designed and manufactured, read this User Guide before operating. In the event of a failure, notify and return the defective unit to ALLEN & HEATH Limited or its authorised agent as soon as possible for repair under warranty subject to the following conditions Conditions Of Warranty 1. The equipment has been installed and operated in accordance with the instructions in this User Guide 2. [. . . ] In the up position the switch selects the PHONO input, indicated by the green led. This input provides standard RIAA equalisation for high quality magnetic cartridge turntables. When pressed, LINE is selected, indicated by the led changing colour to red. Use this to select non-RIAA or alternative stereo music sources. Adjusts the input sensitivity of the channel to match the connected source to the console 0dB operating level. This provides a 20dB range with continuous adjustment for line level signals from ­10dBu to +10dBu. Use the Cue system to correctly set the level. Reduce LEVEL if the red +10 led flashes. Stereo Channels 1 to 4 feature a unique four band equaliser providing infinite attenuation of high and low frequencies and -30dB attenuation of mid frequencies. This provides the DJ with effective equalisation to creatively alter and shape the sound during live performance rather than simply correct source problems. This type of equaliser is known as `asymmetric' because the amount of boost and cut is not the same. Boost is restricted to a safe +6dB to highlight selected sounds while preventing system overload through heavy use. Cut on the other hand, is used to completely suck out affected frequencies allowing two or more tracks to be mixed together without vocals or bass lines clashing. HI Turn this control clockwise to boost and anticlockwise to cut the high (treble) frequencies. This has a shelving response when turned clockwise with all frequencies above the 2. 5kHz turning point affected. When turned fully anticlockwise the response changes to a low pass filter (12dB/Oct) with all frequencies above the cutoff point being progressively attenuated. Use HI boost to brighten up the sound by adding sparkle, and cut to eliminate all HF content. MID 1 Turn clockwise to boost and anticlockwise to cut the higher mid frequencies. This has a bell shaped peak/dip response that has maximum effect at 2kHz. Frequencies in this range can be boosted by 6dB or attenuated by 30dB. The "Q" or frequency bandwidth also alters from a high Q (narrow bandwidth) on boost to a low Q wide bandwidth when cutting. This prevents accumulated gain when all EQ controls are fully clockwise. [. . . ] Refer all servicing to qualified service personnel. The XONE:92 has several internal option settings designed in. Some of these are primarily for setting up the mixer in a fixed installation situation, and the others can be used to reconfigure the MIDI system. To gain access to these options the top panel assembly needs to be separated from the chassis. This operation should only be carried out by qualified service personnel. IMPORTANT! [. . . ]
