The following instructions will give you a brief run-down on the terminology and functions of the VMX100. After reading, please store this manual in a safe place for future reference.

1.1 Before you get started

Your PRO MIXER was carefully packed in the factory and the packaging is designed to protect the unit against rough handling. Nevertheless, we recommend that you carefully examine packaging and contents for any signs of physical damage which may have occurred during transit.

• If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the shipping company immediately. Otherwise, claims for damage or replacement may not be granted. Shipping claims must be made by the consignee.
• If the unit needs to be shipped, please always use the original packaging to avoid damage.
• Never let unsupervised children play with the VMX100 or with its packaging.
• Please dispose of all packaging materials in an environmentally-friendly fashion.

Please take care to always ensure adequate ventilation. Do not place the PRO MIXER near heating units or heat-generating devices in order to avoid overheating.

CAUTION!

We would like to point out that high volumes can permanently damage your sense of hearing and/or your headphone or speaker systems. Therefore, please turn the MAIN control in the MIC/MAIN section all the way to the left before turning on the mixer. And please exercise caution and common sense when setting volume levels.

2. FRONT PANEL

Fig. 2.1 Front view of the PRO MIXER VMX100

(Diagram description: The front panel features controls for two input channels, a PFL section, a MIC/MAIN section, a beat counter, a crossfader, and headphone output.)

2.1 Input channels 1 and 2

The PHONO/LINE switch (1) selects one of the input pairs on the respective channel. The “PHONO” setting (and inputs) are intended for turntables; for all other signal sources, i.e. a CD or MD player, use the "LINE" setting and inputs.

Never connect line-level equipment to the highly sensitive phono inputs! The output levels of phono cartridge systems are in the millivolt range, whereas CD and MD players, as well as tape decks, provide outputs levels in the volt range. In other words, the level of line signals is up to 100 times higher than phono output levels.

The GAIN control (2) is used to adjust the input signal level.

The overall level of your signal is also effected by the EQ settings. It's a good idea to adjust the equalizer before you set the level with the GAIN control.

Each of the two input channels is equipped with a 2-BAND EQUALIZER with kill characteristic. The maximum amount of attenuation (-32 dB) is much higher than the maximum boost (+12 dB), allowing entire frequency spectrums to be "removed" from a track (3).

The CHANNEL fader (4) adjusts the final channel volume.

2.2 PFL section (Pre Fader Listening)

The PFL signal is a pre-fader headphones signal, enabling you to pre-listen to a signal source without effecting the main signal.

• The LEVEL control (5) determines the volume of the headphones signal.
• The MIX control (6) lets you fade between channels 1 and 2.
• The LEVEL METER (7) displays the level of the signal selected via the MAIN/PFL button (8).
• The MAIN/PFL button (8) allows you to route either the main or PFL signal to the display. Remember: “PFL" is your pre-listening or headphone signal and “MAIN” is the signal assigned to the outputs of the VMX100.

In PFL mode, the channel 1 signal is displayed on the left side of the LEVEL METER, and channel 2 on the right.

2.3 MIC/MAIN section

• The MAIN knob (9) controls the overall output volume.
• The MIC LEVEL control (10) adjusts the volume of the microphone signal.

2.4 Beat counter

The PRO MIXER VMX100's built-in beat counter is an extremely useful feature, allowing smooth crossfades between two tracks—an important key to the success of your performance. The beat counter analyzes and displays the tempi of your tracks in BPM (Beats Per Minute). The beat counter sections of channel 1 and 2 are identical.

The tempo of the track is shown in the respective channel's DISPLAY (11). In the case of multiple tempo changes, the display would change continuously, causing unnecessary confusion and rendering the function virtually useless. Enter the SYNC LOCK button (12): with it, you can limit the range of possible tempo values within a song. Pressing this button once the counter has "caught" and displayed a realistic value will simplify things. The BEAT ASSIST button (13) allows you to set the beat counter's tempo manually, similar to "tap tempo". Pressing the button three times in time with the track will set the beat counter and its display at that tempo. The BEAT ASSIST and SYNC LOCK buttons are each equipped with an LED to show that the respective function is activated.

Once the tempo of the two tracks have been determined and locked with the SYNC LOCK or BEAT ASSIST buttons, the tempo difference between channel 1 and 2 will be depicted via the 9-segment TEMPO DIFFERENCE LED display (14). It shows the degree of the tempo difference by a respective deflection to the right (channel 2 track is faster) or to the left (channel 2 track is faster). The center LED lights when the tempi are equal. The synchronization of channel 1 and 2 is shown in the TIME OFFSET LED display (15) below the TEMPO DIFFERENCE display. When the center LED is lit, the tracks are in sync with each other. When the display moves to the left or right, the corresponding channel is running out of sync. The TEMPO DIFFERENCE and TIME OFFSET displays are only active when the tempi of both channels have been locked as explained above.

To exit the SYNC LOCK or BEAT ASSIST mode, simply press the SYNC LOCK key in both channels again.

2.5 Crossfader section

• The CROSSFADER (16) is used to fade between channels 1 and 2.
• The CURVE switch (17), located on the left side of the CROSSFADER, enables you to select between two crossfade modes: SOFT and SHARP. In SOFT mode the crossfader fades between the channels in a linear, continuous manner. This mode is recommended for slower, smoother crossfades. In SHARP mode the crossfader takes on a more logarithmic effect, working faster towards the outer edges of the fader range. Use this mode for faster, "hard" crossfades.

Flipping the CURVE switch may cause a sudden change in volume. We recommend not changing this setting while a signal is present.

• The MIC INPUT connector (18) is a balanced ¼" TRS socket for microphone connection.

We strongly recommend the use of high-grade cables and connectors for the transmission of audio signals. Inferior quality materials cannot supply acceptable audio quality or corrosion protection.

• The HEADPHONES socket (19) allows you to connect your headphones for pre-listening (PFL signal). For best results, use headphones with an impedance rating of at least 32 Ohms.

3. REAR PANEL

With the exception of MIC INPUT and HEADPHONES, all of the VMX100's audio connections are located on the rear panel and supplied as RCA connectors.

Fig 3.1: Rear view of the PRO MIXER VMX100

(Diagram description: The rear panel shows various RCA input/output connectors, a power socket, a fuse holder, and serial number information.)

• The PHONO inputs (20) for channel 1 and 2 are only for turntable connection.
• The LINE inputs (21) may be used for connecting tape decks, CD or MD players etc.
• The GND connection (22) allows grounding of a turntable.
• Use the AMP output (23) to connect the VMX100 to an amplifier. The level is controlled by the MAIN knob in the MIC/MAIN section.

In order to avoid power-up thumps, which can damage your loudspeakers, please power up your amplifier last. There should be no signal present, e.g. no music playing, when you turn on your amp. In addition, we suggest that you set all volume-related controls to “zero” (down) before powering up your system. Following these precautions will save you from unpleasant and potentially dangerous surprises.

• The TAPE output (24) enables you to record your performance by connecting a tape deck, DAT recorder etc. Unlike the AMP output, the TAPE level is fixed, so that you have to adjust the input level on the recorder.
• The POWER ON switch (25) turns on the PRO MIXER.
• FUSE HOLDER/VOLTAGE SELECTOR (26). Before you connect the equipment to an AC outlet, please be sure that the voltage displayed corresponds with your local AC voltage. If you should need to replace the fuse, be sure to replace it with one of the same type and value. Some units allow you to switch between 240 V and 120 V by rotating the fuse holder.

To operate the unit at 120 V, you must install a fuse with the double ampere rating.

• This is the socket for the power cable (27). The impulse behavior of any given amplifier circuit depends largely upon the power supply's inherent reserves. All mixers contain numerous operational amplifiers (op-amps) for processing line-level signals. Due to the restricted performance of their power supplies, many mixers show “stress symptoms” when used under extreme conditions, resulting in inferior audio quality. Thanks to its generously proportioned power supply, this will never happen to your VMX100: The sound will always be clear, transparent and powerful.
• SERIAL NUMBER (28). Please take the time to fill out and return the warranty card within 14 days after the date of purchase. This will entitle you to all the benefits of our extended warranty. Alternatively, you can register online at www.behringer.com.
