Before You Begin; Metering; Psu (Power Supply Unit); Warranty - Behringer Eurorack MX1804X User Manual

Stereo aux/FX returns (additional stereo line inputs)
The MX1804X features two balanced aux returns. These inputs are perfectly suited for effect returns and tape
returns from multitrack machines. The aux returns may also be used for mixing in extra MIDI instruments etc.
The second return usually serves for the internal effects device. But you can also use it as additional line input.
Main mix output
The main mix output level is controlled via a pair of high-quality true-log 60-mm stereo faders and is monitored
by a pair of accurate 12 segment bargraph peak meters, surrounded by 4 status LEDs.
24-bit digital effects processor
The integrated 24-bit digital effects processor offers first-class algorithms, which are also used in our
VIRTUALIZER. The effects device features all standard effects (reverb, chorus, flanger, delay, etc.) and—due to
its excellent quality—it can be used for mix down situations and live applications as well.
7-band graphic equalizer
As a special feature the MX1804X owns a 7-band graphic equalizer. The equalizer allows for quickly providing
the finishing touch to your overall sound in live performances or mix down.
Additionally, your MX1804X provides an adjustable headphones output, a separate 2-track in-/output and the
above mentioned Alt 3-4 output. There are inserts for the mono channels, the Alt 3-4 and the main mix bus.

1.2 Before you begin

1.2.1 Metering

The channels 1 to 6 have peak LEDs, while the L and R outputs have 12 segment bargraph meters. The
L/R meters double up as mono PFL or stereo solo meters.
The meters should average around 0 dB during loud passages. If they read persistently higher, or are peaking
above +10 dB, reduce either the main L/R faders and/or channel faders, or (as a last resort) channel input gain.
Maybe it's time to do a round of PFL metering.

1.2.2 PSU (power supply unit)

Any amplifier circuit is limited in its transient response by the available current. Every mixer has numerous line level
operational amplifiers (op-amps) inside. When being driven hard, many desks begin to show signs of stress due to
power supply limitations. Not so with the EURORACK MX1804X. The sound will always stay clean and crisp right
up to the operating limits of the op-amps themselves, thanks to our generous 40 W external power supply unit.
Please connect the PSU with the EURORACK MX1804X PSU connector
and switch on your MX1804X with the power switch
+
Do not connect the PSU to the EURORACK while the PSU is connected to the mains supply.
Connect switched-off desk and PSU first before you connect the PSU to the mains supply.
Lastly switch on desk.

1.2.3 Warranty

Please take the time to have the warranty card filled out completely by your specialized dealer, and return it
within 14 days after the date of purchase, so as to be entitled to benefit from our extended warranty. You may
also use our online registration option available on the Internet at www.behringer.com. You will find the serial
number of your MX1804X on the rear panel.

1.2.4 Packing

Your BEHRINGER EURORACK was carefully packed in the factory and the packaging was designed to
protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and its contents for any signs of physical damage, which may have occurred in transit.

company immediately, otherwise claims for damage or replacement may not be granted.
