7PRO MIXER DJX900USB User Manual

When you have limited the tempo of the tracks on both channels with the SYNC LOCK or BEAT ASSIST buttons, the difference in tempo from both channels is illustrated in the form of a nine-character message on the TEMPO DIFFERENCE- LED (24). The extent of the difference in tempo is indicated by a corresponding swing to the right (signal A is slower) or to the left (signal B is slower). When the middle LED lights up, the tempi are the same. The TIME OFFSET LED (23) below that displays the signal A and B synchronisation. Should the middle LED light up, the tracks are synchronised. Should the display move to the left or right, the channels are not synchronised. The TEMPO DIFFERENCE and TIME OFFSET displays are only active if the tempi of both channels have been fixed in one of the ways described.

When no signal is present (or when the signal level is too low), the BPM display shows only dashes. When the signal is present but can not

be identified, the display shows 160 BPM and then shows the said dashes. The beat counter then attempts to get another readout. Therefore, “160” BPM is no usable value; rather, it is simply an error message when the signal can not be analyzed.

To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button once more on both channels.

The DJX900USB features an internal digital effects processor into which you can feed your master signal, the signals of the input channels or the mic signal. The module provides a number of standard effects, such as reverb, delay and echo, as well as various filter and modulation effects.

To select the signal to be processed, use the SOURCE selector (33).

Turn the PROGRAM control (35) to select an effect. The corresponding program number appears on the PROGRAM display (34).

Press and hold the PROGRAM control for about 2 seconds to load the selected preset.

When the new effect has been loaded, turn the PROGRAM control (35) to change the effect’s parameters. The parameter value is shown on the display.

View the table (column “Ajustable Parameter”) to see which parameter of the selected effect can be modified.

The parameter values of the delay and echo effects are displayed in BPM (beats per minute). The selectable range is from 80 to 160 BPM. The display only shows two digits and so values of 100 and above are represented with a dot behind the number (for example, 120 BPM is displayed as “20.”).

Use the LEVEL control (36) to determine the volume level of the effect signal.

Activate the effect signal by pressing the FX ON switch (37).

Press the PROGRAM control one more time to use it for selecting effects again.

9. Connections

9.1 Rear panel connectors

(38)These are the LINE i. e. CD inputs to connect a tape deck, CD or MD player etc. Unlike other channels, channel 1 features two line inputs.

(39)The PHONO inputs for channels 2 to 4 are for connecting a turntable.

(40)The connectors ground the turntables.

(41)With the PHONO/LINE switch it is possible to switch the input sensitivity of the PHONO inputs 2 to 4 to line level. This allows you to connect a tape deck or a CD player to the PHONO inputs.

(42)The DJX900USB features an integrated effects loop for the connection of an external effects device. The MONITOR signal is taken at the SEND output and routed, for example, to a reverb processor. Thus, the signal at the SEND connector is identical to the headphones signal and is selected with the MONITOR CUE buttons (16).

(43)The externally processed signal is added to the MASTER output signal via the RETURN connectors. The effect signal volume may only be adjusted at the output control of the effects device itself.
