Frequently Asked Questions - PROMIX230DSP HQ Power

How to connect a microphone to the mixer?

Plug your microphone into the combo XLR/1/4" jack on the front panel. Adjust the level using the GAIN microphone knob (range from -30 dB to +52 dB). Use the MIC switch to turn the microphone on (ON) or off (OFF). The O'RIDE mode automatically attenuates the channel signal by -12 dB when you speak.

How to activate and use the DSP effects?

Select an effect using the EFF buttons (hold to scroll quickly). The LCD display shows the name and number of the preset (1 to 99). Press DSP ON to enable/disable the effect. Adjust the effect volume with the LEVEL knob. Use the ASSIGN selector to choose the source to process.

How to sync the BPM of two tracks?

The automatic BPM counters display the tempo of each channel with an accuracy of ±1 beat. Adjust the turntable speed using the pitch controls so that the BPM match. The BPM OFFSET LED indicator (7 LEDs) helps: LEDs light up on the side of the faster channel; the central blue LED indicates perfect sync. Note that the LEDs only function if the difference is less than 10 BPM.

What to do if the crossfader is not working properly?

The crossfader is replaceable. First check if the X Reverse switch is not activated (it reverses the crossfader effect). If the problem persists, you can replace the crossfader yourself or contact your dealer. Make sure the level sliders are not at minimum.

How to use the Punch function?

The PUNCH function (button pressed) creates an effect by transposing the program from one side of the crossfader to the other. This allows for quick transitions or rhythmic effects. The punch acts on the signal selected by the crossfader.

Why is there no sound in the headphones?

Check that the headphones are plugged into the PHONES jack (1/4" stereo) and that the PHONES LEVEL is high enough. Make sure the CUE selector is activated for the desired channel. The PHONE MIX knob allows mixing the cue signal and the output signal; turn it left to hear only cue, right for output.

How to quickly cut low, mid, or high frequencies?

Use the HI Kill, MID Kill, and LO Kill buttons on each channel. Pressing a button immediately cuts the corresponding frequency band (-26 dB), regardless of the equalizer setting. Release to restore sound.

What is the supply voltage and what to do if the fuse blows?

The device operates at 230 VAC / 50 Hz. The fuse is located in the IEC connector (20 mm). To replace it, first unplug the mixer from the mains, then replace the fuse with an identical model (see specifications on the back of the device). Never use a fuse of different value.

How to clean the mixer?

Always unplug the device before cleaning. Use a soft, dry cloth. Do not use liquids, abrasive cleaners, or solvents. Avoid letting water or products enter the inside of the device, as this could cause irreversible damage.

What to do if the LCD display shows nothing or is abnormal?

Check that the device is on (POWER switch pressed) and that the power indicator is lit. If the screen remains blank, the DSP processor may be in muted mode: the message [EFFECT MUTED] displays if the effect is disabled. Make sure DSP ON is enabled. If the problem persists, contact after-sales service.

4. Controls (see fig. on page 2)

1. Power Switch

Press to switch the mixer on or off. Make sure to switch on the mixer before switching on the amplification system.

2. Power Indicator

This LED burns when the mixer is switched on.

3. Output Level

This knob controls the overall level leaving the mixer at the master outputs.

4. Headphone Mix

Move to the left to route the cue signal to the headphones and monitor display. Move to the right to send the output signal to the headphones and monitor. Any position between these extremes is a variable mix of the cued input signal and the mixer output.

5. Headphones Socket (standard 14 " phone plug)

This is a stereo front-mounted phone jack (L channel = tip, R channel = ring, ground = sleeve, min. load impedance = 32Ω, output level = 50mW).

6. Headphones Level

Set the desired level of the headphones.

7. Punch Button

Press to create effects by transposing the program from one side of the crossfader directly onto the other side.

8. Input Selector

Each input channel has three stereo input options. This switch lets you select which of the inputs plugged into your mixer you wish to use. Both channels have 1 phono input, 1 CD input and 1 line input.

9. Gain Control

Each input channel has a gain control offering a < -80dB +10dB gain range to allow compensation for differing input levels.

The 3-band EQ not only offers an ample 12dB boost but each EQ band can be attenuated by at least 26dB. This provides the ability to cut certain frequencies such as bass and treble.

10. EQ Control HI

Cut and boost control over high frequencies.

11. EQ Control MID

Cut and boost control over mid frequencies.

12. EQ Control LO

Cut and boost control over low frequencies.

13. HI Kill Button

Instantly removes the high frequencies from the input signal, regardless of the HI EQ control setting.

14. MID Kill Button

Instantly removes the mid frequencies from the input signal, regardless of the MID EQ control setting.

15. LO Kill Button

Instantly removes the low frequencies from the input signal, regardless of the LO EQ control setting.

16. Cue Selector

This control selects the input signal on the respective channel and routes it to the cue channel on the headphones and monitor.

17. Input Fader

This is a 45mm fader for controlling the mix level of the input to the main output.

18. Crossfader

This is a fast-action, dipless crossfader between the input channels. The dipless action means that the signal only changes in level after the halfway point.

19. Crossfade (X) Reverse

Selecting this switch reverses the operation of the crossfade.

ABS (auto beat sensor) BPM counters: Each channel has a 3-digit display that gives a BPM read-out of the music content on that channel to an accuracy of +/- 1 beat. The ABS will update approximately every 2.5 seconds with each change of BPM. This facility is intended as an aid to beat matching, i.e. by using the pitch control of the input source(s) you can match the BPM of one source to another. To achieve this most effectively, tracks containing a strong, constant beat should be used.

Tracks that do not contain clear and constant beats will not be accurately tracked by the ABS and will therefore produce erratic readings.

1. BPM Display Channel 1
2. BPM Display Channel 2
3. BPM Offset Indicator

This is an additional feature to the BPM display that allows you to visually track the difference in BPM between the two music sources. The 7-LED display will illuminate a single LED at a time and favour towards the channel with the faster BPM, e.g. if channel 1 is faster the lit LED will be towards the left and towards the right for channel 2. When the BPMs are matched the blue LED in the centre of the display will illuminate. For this feature to function, the difference between the two sources must be 10 BPM or less. If the difference is greater, the LEDs will not light.

1. Microphone Input

An XLR and 14 " jack combination is mounted on the front face of the mixer offering a balanced or unbalanced connection.

1. Microphone Gain

This control changes the level of the microphone. It will accommodate most microphones of both low and high impedances up to 600 (range < -30dB +52dB ).

1. Microphone EQ Control HI

Cut and boost control over high frequencies of the microphone input.

1. Microphone EQ Control LO

Cut and boost control over low frequencies of the microphone input. Excessive bass can lead to amplifier overload on the mixer output. If distortion is heard, reduce the gain control to compensate.

1. Microphone Function Switch

This switch offers the facility to attenuate the main music program automatically when the microphone input is active. OFF: this switches the microphone signal off.

ON: this places the microphone on air.

O'RIDE: when selected, the live music program will be attenuated by 12dB when the microphone is used.

1. Cue/Output Display

A 10-segment LED ladder with PPM characteristics and peak hold facility on - 9dB +8 dB relative. Indication range is 22 +8dB

Digital Signal Processor

1. LCD

2 lines and 16 characters LCD interface which indicates all 99 preset names plus an audio input level meter. The upper display line is acting as an analogue bargraph level meter. The indicated audio level is independent of the selected preset. If the effects switch is switch off, the bargraph level meter indication will be replaced by [EFFECT MUTED]. The lower display line indicates the selected preset with number and the associated name (see table on page 3).

30.Assign

This selector lets you determine which input signals are routed to the DSP processor.

1. Effect On Switch

Use this switch to run the effect on or off.

1. Up/Down

These keys allow you to select the different programs. A continuous pressed key will increase the preset number at scrolling speed.

1. Return Level Control

This control is used to determine the volume of the effects signal.

1. Phono Inputs

Stereo phono inputs (input impedance = 47k source impedance = typical magnetic cartridge, input sensitivity = 5.5mV RMS (- 42dBu) max.).

1. CD Inputs

Input impedance = typically 10k Ω, source impedance = 2k Ω max., nominal sensitivity = 775mV RMS (0dBu).

38. Unbalanced Master Output (Low)

Output is provided by standard unbalanced phono sockets. Level = 0dBu (775mV RMS), output impedance = < 50Ω, load impedance = 5k Ω max.

39. AC Power Socket

A standard IEC socket is provided to connect the mixer via the supplied lead to the local AC power supply. The power consumption of this mixer is 15V.

WARNING: THIS MIXER MUST BE EARTHED FOR SAFETY AND GOOD GROUNDED PRACTICES IN MIXING

In the event of ground-loop problems in the audio system, DO NOT disconnect the AC supply earth to any equipment before consulting the equipment instruction manual. Most power amplifiers have audio ground lift switches or are designed specifically to avoid ground-loop problems connected to earthed mixers.

Ensure the mixer has a clean AC supply from the mains socket that is not used for other equipment that would lead to interference such as lights, refrigerators, etc.

The IEC power socket has an internal fuse holder that takes a 20mm fuse. Always replace a blown fuse with the same type as specified on the rear of the mixer. Always disconnect the AC power cord before changing the fuse.
