ACHTUNG: Um die Gefahr eines Brandes oder Stromschlags zu verringern, soll-
ten Sie dieses Gerät weder Regen noch Feuchtigkeit aussetzen.Um die Gefahr
eines Stromschlags zu verringern, sollten Sie weder Deckel noch Rückwand des
Geräts entfernen. Im Innern befinden sich keine Teile, die vom Anwender
gewartet werden können. Überlassen Sie die Wartung qualifiziertem
Fachpersonal.Der Blitz mit Pfeilspitze im gleichseitigen Dreieck soll den Anwender
vor nichtisolierter “gefährlicher Spannung” im Geräteinnern warnen. Diese
Spannung kann so hoch sein, dass die Gefahr eines Stromschlags besteht. Das
Ausrufezeichen im gleichseitigen Dreieck soll den Anwender auf wichtige
Bedienungs- und Wartungsanleitungen aufmerksam machen, die im mitgelieferten
Informationsmaterial näher beschrieben werden.
Wichtige Sicherheitsvorkehrungen
1. Lesen Sie alle Anleitungen, bevor Sie das Gerät in Betrieb nehmen.
2. Bewahren Sie diese Anleitungen für den späteren Gebrauch gut auf.
3. Bitte treffen Sie alle beschriebenen Sicherheitsvorkehrungen.
4. Befolgen Sie die Anleitungen des Herstellers.
5. Benutzen Sie das Gerät nicht in der Nähe von Wasser oder Feuchtigkeit.
6. Verwenden Sie zur Reinigung des Geräts nur ein feuchtes Tuch.
7. Blockieren Sie keine Belüftungsöffnungen. Nehmen Sie den Einbau des
Geräts nur entsprechend den Anweisungen des Herstellers vor.
8. Bauen Sie das Gerät nicht in der Nähe von Wärmequellen wie Heizkörpern,
Wärmeklappen, Öfen oder anderen Geräten (inklusive Verstärkern) ein, die
Hitze erzeugen.
9. Setzen Sie die Sicherheitsfunktion des polarisierten oder geerdeten Steckers
nicht außer Kraft. Ein polarisierter Stecker hat zwei flache, unterschiedlich breite Pole. Ein geerdeter Stecker hat zwei flache Pole und einen dritten
Erdungsstift. Der breitere Pol oder der dritte Stift dient Ihrer Sicherheit. Wenn
der vorhandene Stecker nicht in Ihre Steckdose passt, lassen Sie die veraltete
Steckdose von einem Elektriker ersetzen.
10. Schützen Sie das Netzkabel dahingehend, dass niemand darüber laufen und
es nicht geknickt werden kann. Achten Sie hierbei besonders auf Netzstecker,
Mehrfachsteckdosen und den Kabelanschluss am Gerät.
11. Ziehen Sie den Netzstecker des Geräts bei Gewittern oder längeren
Betriebspausen aus der Steckdose.
12. Überlassen Sie die Wartung qualifiziertem Fachpersonal. Eine Wartung ist
notwendig, wenn das Gerät auf irgendeine Weise, beispielsweise am Kabel
oder Netzstecker beschädigt wurde, oder wenn Flüssigkeiten oder Objekte in
das Gerät gelangt sind, es Regen oder Feuchtigkeit ausgesetzt war, nicht
mehr wie gewohnt betrieben werden kann oder fallen gelassen wurde.
WARNING: To reduce the risk of fire or electric shock, do not expose this unit to
rain or moisture. To reduce the hazard of electrical shock, do not remove cover or
back. No user serviceable parts inside. Please refer all servicing to qualified personnel.The lightning flash with an arrowhead symbol within an equilateral triangle,
is intended to alert the user to the presence of uninsulated "dangerous voltage"
within the products 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 product.
Important Safety Instructions

Controls and Functions
MONO/STEREO INPUT CHANNEL SECTION
The following section details each part of the MDR1064’s MONO INPUT CHANNELS including the GAIN control, LOW CUT switch, 3-BAND EQ, AUX sends, PEAK LED, PAN and LEVEL controls. The input channels one
through six on the MDR1064 feature high quality, discrete transistor pre-amp providing transparency and
extended dynamic range.
GAIN
The MDR1064’s pre-amp stage has a variable GAIN control with a range of 5
to 60dB on the MIC input and –26 to +26dB on the LINE input.
LOW CUT FILTER
Each of the MDR1064’s first six channels include a LOW CUT (or high pass)
filter which rolls off the low frequencies from 75Hz and below at the rate of
18dB per octave. The LOW CUT filter allows you to remove the lower frequencies that you sometime just don’t want to pick up. For example, when you are
miking a high-hat you only want to capture the frequencies that the hi-hat is
producing. Therefore, by using the LOW CUT filter, you can reduce the
amount of pick-up from the low toms and bass drum that may leak into the hihat mic. You can use the same technique on other instruments like acoustic
guitar, violin, piano and even on vocals. In live sound applications, the LOW
CUT filter is especially useful for removing stage rumble.
CHANNEL EQUALIZER
The MDR1064 input channels feature a 3-band equalizer allowing you to
adjust the high, mid, and low frequencies independently on each channel. The
channel’s frequency response is flat when the knobs are in the "12:00" position. Rotating the knob towards the right will boost the corresponding frequency band by 15dB, and rotating it towards the left will cut the frequency by
15dB. The frequency centers, range of boost or cut, and equalizer type for
each band are as follows:
High: 12KHz +/- 15dB shelving type
Mid: 2.5KHz +/- 15dB peaking type
Low: 80Hz +/- 15dB shelving type
AUX 1
The MDR1064 has two auxiliary sends which can be used for sending signals
to external effects devices or for creating a monitor mix. The AUX1 section is
often used for a monitor mix in a live sound mixing, or for a headphone mix in
a recording application. Each input channel includes an AUX 1 send which
controls the amount of that channel’s signal that is sent to the AUX bus.
NOTE:
The AUX1 controls are "PRE-FADER SENDS" which means they are
not affected by the FADER level settings of each channel. This allows you to
create a mix for the monitors that is independent of the main LEFT and RIGHT
MIX.
AUX 2
The channel’s AUX 2 knob controls the amount of signal that is sent to the AUX 2 bus. The AUX 2 signal
can be sent to an external effects device connected to the AUX 2 OUT jack located in the MASTER SECTION jack field.
