[. . . ] USER GUIDE Publication AP4145 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 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. [. . . ] When pressed, LINE is selected, indicated by the led changing colour to red. 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, ­40dBu to ­20dBu for mics, or to match a wide range of RIAA turntable cartridges. It provides a powerful tool to adjust the tonal quality of the sound to correct source problems such as microphone characteristics, proximity effect, noise and feedback, or to adjust the overall `feel'. The XONE:62 equaliser provides separate tone control over four frequency bands. HI Turn this control clockwise to boost and anticlockwise to cut the high (treble) frequencies. This has a shelving response with all frequencies above the 10kHz turning point affected. Note that frequencies below 10kHz are affected by a decreasing amount. Use HI boost to brighten up the sound by adding sparkle, and cut to reduce source hiss and ambient high frequency pickup, or to limit or lift the high response of vocal mics. 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 2. 5kHz. On the other hand, some situations may require cutting to notch out a ringing frequency so increasing gain before feedback. MID 2 This is similar to MID 1 but affects the lower mid frequencies centred at 250Hz. Boosting can enhance the warmth of the sound while cutting can reduce the unpleasant resonant or boomy effects. LO This is similar to the shelving HI control but affects the low (bass) frequencies below the 100Hz turning point. Note that frequencies above 100Hz are affected but by a decreasing amount. Use LO boost to enhance low end punch, or cut to reduce source hum and rumble, or to remove the bassy sound of vocal mic proximity effect. CH3-6 feature a unique four band equaliser similar to CH1 and 2 but providing a very different function. While the centre frequencies are the same, The range of boost and cut is different to better suit music mixing. 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 increased to a huge ­26dB to completely suck out affected frequencies dramatically changing the effect. [. . . ] It is well known that many audio system problems are due to faulty cables and connectors. In a club or similar installation strict SOUND LEVEL and noise regulations may apply. Check that the turntable earth strap has been correctly connected to the console chassis earth post. Also check that the turntable headshell and cartridge are correctly aligned and plugged in.
