IMPORTANT SAFETY INSTRUCTIONS CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE AVIS: RISQUE DE CHOC ELECTRIQUE. NE PAS OUVRIR These symbols are internationally accepted symbols that warn of potential hazards with electrical products. The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 1. [. . . ] Cables The inputs and outputs are balanced on conventionally wired XLRs (pin 1 screen, pin 2 hot and pin 3 cold). This product should only be used with high quality, screened twisted pair audio cables, terminated with metal-bodied 3-pin XLR connectors. Any other cable type or configuration for the audio signals may result in degraded performance due to electromagnetic interference. Note: The +48V phantom power can only be used with balanced cables. Electric Fields Should this product be used in an electromagnetic field that is amplitude modulated by an audio frequency signal (20Hz to 20kHz), the signal to noise ratio may be degraded. Degradation of up to 60dB at a frequency corresponding to the modulation signal may be experienced under extreme conditions (3V/m, 90% modulation). 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. [. . . ] You can also use the XL42 EQ and bypass your console's EQ. Set PAN to off for mono operation or on for stereo operation. As a better EQ section for your console. Plug the XL42 into the insert point of your console (Desk Send to XL42 Input and XL42 Output to Desk Return). Set the PAD switch on the XL42 to the in position in for a line level signal. As an expansion to your console. [. . . ]
