1.2 Before you begin

1.2.1 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 MX1604A. 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.
+
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 by
supply unit to connect the MX1604A to the mains (see Chapter 9.1 “Specifications” for details).

1.2.2 Warranty

Please take the time to fill out and return the warranty card within 14 days from the date of purchase, so as to
be entitled to benefit from our extended warranty. Or use our online registration option available on the Internet

1.2.3 Packing

Your BEHRINGER MX1604A 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.
+
If the unit is damaged, please do not return it to us, but notify your dealer and the shipping
company immediately, otherwise claims for damage or replacement may not be granted. Ship-
ping claims must be made by the consignee.

1.2.4 Rack mounting the MX1604A

Enclosed in the shipping box you will find a rackmount kit. If you want to make your MX1604A a rack mixer,
losen the screws on the side panels and use them to fix the rack ears (note, that there is a left and a right
one).
+
Be sure that there is enough space around the unit for cooling and please do not place the
MX1604A on high temperature devices such as power amplifiers etc. to avoid overheating.
+
When switched on, parts of the desk and the power supply unit will become very warm, this is
normal during operation.
