[. . . ] Name: Simon Harrison Date: 7th May 2004 Authority: Research & Development Director, Klark Teknik Group (UK) PLC Attention!Where applicable, the attention of the specifier, purchaser, installer or user is drawn to special limitations of use which must be observed when these products are taken into service to maintain compliance with the above directives. Details of these special measures and limitations to use are available on request and are available in product manuals. A Subsidiary of Telex communications, Inc. Contents Contents Thank you for using a Midas XL42 dual channel creative equaliser. The XL42 has been developed to meet the needs of demanding live sound engineers and meets the quality of build and performance that you would expect from a Midas product. [. . . ] No permanent damage or degradation of performance will be caused by these conditions. XL42 Operators Manual - Page 2 After You Have Unpacked the Unit Before unpacking the XL42, check packaging for signs of damage, as this could be an indication of damage to the unit inside. After unpacking the XL42, check the unit for signs of damage to the casing. Damage to consignments must usually be reported to the courier within 24 hours in order for a claim to be made. Please retain the packaging for your XL42, as it will prove useful if you need to transport the unit. Please also retain the XL42's Operators Manual (this document) and any other associated documentation. XL42 Operators Manual - Page 3 After You Have Unpacked the Unit XL42 Operators Manual - Page 4 Front Panel The XL42 is a highly featured 1U 19" rackmount, dual channel strip. The unit is split into two identical channel strips, each with identical functionality but having independent inputs and outputs. Power On/Off switch: Conventional latching type switch, which is on when in its fully in position and off when fully out. The action of the switch is firm but does not require excessive force, which may damage the unit. A red LED, to the left of the power switch, illuminates to indicate that the XL42 is receiving mains power. Output section EQ section Input section XL42 Operators Manual - Page 5 Front Panel Input section mic/line gain control knob: Gives a continuously variable input gain control depending upon the input selected, where: Mic: +15dB to +70dB gain Mic (PAD enabled): -10dB to +45dB Ø switch: Phase switch inverts the input signal by applying a 180° phase shift. +48 switch: Phantom power +48V switch allows connection of devices that require phantom power, such as, condenser microphones, direct inject (DI) boxes etc. PAD switch: The line/pad switch provides 25dB of attenuation to the input signal and allows the connection of high output microphones or line level signals. If using the XL42's optional transformercoupled input, the pad greatly reduces the risk of saturation at very low frequencies. XL42 Operators Manual - Page 6 Front Panel EQ section The bass, lo-mid, hi-mid and treble bands use dual concentric rotary controls. The outside ring controls the band cut and boost in the range -15dB to +15dB. The inner ring of the dial controls the bandwidth of the filter in the range 0. 1 to 2 octaves (with a centre detent at 0. 5 octave). bass dual concentric rotary control knob: Bass band gain/attenuation adjustment is via inner control knob. Bass bandwidth is adjusted using the outer control ring, enabled via bell switch (immediately below). lo-mid dual concentric rotary control knob: Lo-mid band gain/attenuation adjustment is via inner control knob. Lo-mid bandwidth is adjusted using outer control ring. treble dual concentric rotary control knob: Treble band gain/attenuation adjustment is via inner control knob. Treble bandwidth is adjusted using outer control ring, activated by bell switch (immediately below). freq (lo-cut) control knob: Lo-cut filter control selects the HPF frequency and is continuously variable from 20Hz to 400Hz. By default, this is post-output level and pan, although it may be internally set to be pre-level pan and insert. INS switch: Selects whether the insert circuitry is patched into the audio signal path. When the switch enabled (on, fully in position) then the insert jacks are patched into the audio signal path. Note: the insert point can be configured internally using jumpers to be pre- or post- EQ. The factory default setting is Pre-EQ. MUTE switch: Mutes the channel outputs. Mute may also be controlled via the Automute link selected via the "REMOTE CONTROL AUTOMUTE ASSIGNS" DIP switches on the rear panel PAN switch: Enables the pan control on the level/pan dual concentric rotary control knob.

Your XL42 should come complete with the correct IEC mains lead for the country in which it was intended for sale. If replacing the mains lead, replace with a recommended part and ensure that the fuse is of the correct type. The XL42 must be earthed.

Here the output from the master console (any MIDAS XL series) is inserted at the top of the chain and linked into each unit.
