EURORACK MX1604A

The configuration is 16 into 4 (2+2) into 2. There are four mono channels, four stereo channels and two stereo

Aux Returns. In addition there is a 2-Track input routable to the Main Mix. A channel is always routed to the

Main Mix outs unless Alt 3-4 is selected, in which case its signal is sent to outputs 3 and 4 instead.

Outputs 3 and 4 may be blended with the Main Mix at the Control Room output via a switch . Beside that

the Alt 3-4 signal can also be fed into the Main Mix by pressing Alt 3-4 To Mix. .

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 on the back panel. Use only the correct BEHRINGER power

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

at www.behringer.com.

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.

2. MONO INPUT CHANNEL

Each channel is equiped with a balanced Line input 1/4" jack socket and an XLR Mic input .

Phantom powering is switchable from the back panel .

Note: When using the Mic input please make sure nothing is connected to the same channels Line input, and

vice versa.

The gain circuit has an unusually wide range, obviating the need for Mic/Line switching. The crucial operating
