Introduction The Midas XL42 is a 1U rack mounting, dual channel creative equaliser incorporating the XL4 four-band parametric equalisation and XL4 mic/line pre-amplifiers with +48V phantom power. Each channel has input gain, output level and pan rotary controls, 10-segment LED metering plus a switchable insert send and return point. The XL42 also features Automute scene control from the Automute masters of XL consoles, which are enabled by DIP switches on the rear of the unit.
Before You Start Installation Precautions Do not install this unit in a location subjected to excessive heat, dust or mechanical vibration. Allow for adequate ventilation around the unit, making sure the unit's vents are not obstructed. To avoid excessive heating of the unit, avoid mounting the unit directly above power amplifiers or other devices that radiate significant amounts of heat. Where necessary, use fan-cooled racks.
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.

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.
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.
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.
Front Panel Output section level/pan dual concentric rotary control knob: Adjusts pan or output level. Pan control places the input within a stereo (left/right) mix and has a constant power law such that, at its centre position, each output is attenuated by 3dB. Pan control is enabled by the PAN switch (immediately below) and is adjusted using the outer control ring. With PAN switch off, the XL42 is essentially two independent channel strips.
LEFT INPUT LEFT LINK INPUT RIGHT INPUT RIGHT LINK INPUT RETURN SEND RETURN SEND The XL42 rear panel houses both the input and output sockets as well as the insert points, remote control and Automute sockets, and power inlet and selector.
Rear Panel Left and right link inputs: When used in a daisy chain, the link input is summed with the output from the XL42's input channels to the output so that the daisy chain may continue. A much larger console can be created by adding extra XL42s using the output from the last XL42 in the chain as the master output.
Rear Panel Supply voltage selector switch: The supply voltage is switchable between 115VAC and 230VAC, and should be set to the mains power supply available in the country in which the unit is to be used. Caution! The supply voltage selector switch must be set BEFORE plugging the unit into the mains. UNDER NO CIRCUMSTANCES should the switch be changed whilst the unit is plugged in. Remote Control Automute Assigns: The 9-pin plug for the Automute system allows up to 8 Automute channels.

System Connection The XL42 is a versatile expansion to any system, or a complete system on its own. You can use it: As a replacement for an inferior mic pre-amp. ! Plug the microphone or DI box into the XL42 and the output into the line input of your console. 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.
Auto-Mute Operation The XL42 can be used within an Automute system. The standard 9-pin plug can control up to eight independent mono channels, each of which can be addressed by the XL42. To assign an Automute address for each channel, the REMOTE CONTROL AUTOMUTE ASSIGNS should be turned on for the desired Automute address, that is, LEFT ASSIGN 2 would make the left-hand channel of the XL42 mute on channel 2 of the Automute system.
Daisy-Chain Operation A number of XL42s can be connected in a daisy chain configuration to form a larger console or to expand an existing console. (32 channels of XL quality EQ and mic pre-'s will fit into a 16U.
