Introduction This section briefly describes the possibilities of the PMX124 Mixing Console. T he PMX124 Mixing Console was developed as an easy to use, flexible solution for multifunctional use.
1 Chapter Environment Do not place this unit in an enclosed environment such as a bookshelf or closet. Ensure that there is adequate ventilation to cool the unit. Do not place the unit in environments which contain high levels of dust, heat, moisture or vibration. Do not use the unit near water or other liquids. Make sure no water or other liquids can be spilled, dripped or splashed on the unit. This unit was developed for indoor use only. Do not use it outdoors. Do not place objects on top of the unit.
Safety Requirements Always handle the unit with care. Only use a grounded socket outlet and a power cord with grounding plug to plug in the unit. This unit is not a toy. It should not be operated by children. Do not stick objects through ventilation openings. Do not open the unit (risk for electrical shock). CAUTION – SERVICING This unit contains no user serviceable parts. Refer all servicing to qualified service personnel. Do not perform any servicing unless you are qualified to do so.
2 Chapter Front Panel Controls Channel Control Section 1. Peak LED indicator: These LED indicators light-up when the level of the input signal reaches 5 dB below the channel’s clipping point. It shows the level of the POST-EQ /PRE fader signal. When it lights up frequently, the ‘Trim Control’ potentiometer has to be used to decrease the input sensitivity of the channel. When this causes no improvement, the output level of the connected source has to be reduced. 2.
5. Aux controls: The Aux knobs controls the level of the signals that are sent to the Aux bus. 6. PRE / POST switch: This button determines whether the AUX signal is Pre Fader (signal level is not influenced by fader position) or Post fader (signal level is influenced by fader position). 7. EFX controls: These knobs control the level of the signals sent to EFX bus.
Main Control Section 1. DSP program display: This display shows the program number of the selected effects program. 2. DSP program select switch: This program knob allows you to select one of the 100 digital effects of the built-in 24 bit, high quality, digital signal processor. Some of these effects are Delay, Chorus and Reverb. 3. AUX PRE control: Use this control to adjust the signal level that is sent from the internal digital effect to the AUX bus. 4.
. Main L/R master fader: This fader adjusts the final signal level sent to the ‘MAIN L/R’ output. 11. Level-Meter Signal Buttons: Use these buttons to determine the signal that is sent to the ‘Control Room’ and/or ‘Headphone’ outputs. The illustration below shows how the button settings correspond to the signal selection. 12. Control room / Phones control: This knob controls the level of the signal that is sent to the ‘Control Room’ Jacks or the ‘Headphone’ Jack. 13.
19. Phantom power switch: Use this switch to toggle the phantom power ON and OFF. When the switch is turned ON, the mixer supplies phantom power to all channels that contain XLR Mic input connectors. Turn this switch ON when using one or more condenser microphones, however the switch may be left on when connecting balanced dynamic microphones. NOTE: When this switch is on, the mixer supplies +48V DC power to pins 2 and 3 of all XLR-type ‘Mic Input’ connectors.
3 Chapter Connections and Connectors Front panel connections 1. Channel input jacks: - MIC JACKS: 3-pin XLR connectors are used for the connection of balanced low impedance microphones. - BALANCED LINE IN JACKS: Standard ¼ ” TRS (Tip, Ring, Sleeve) phone jacks are used for balanced or unbalanced line level signals. Some examples of line level equipment include most electronic keyboards, synthesizers, turntables(with appropriate preamps), tape decks and the line outputs from other mixers.
2. Channel insert I/O jack: These are ¼ " TRS (Tip, Ring, Sleeve) phone Jacks which support bi-directional operation. These input/output jacks are located between the head-amplifier and the high pass filter. They can be used to connect these channels independently to your own graphic equalizers, compressors, noise filters, or other devices. NOTE: Connection to an I/O Jack requires a special separately sold insertion cable. It is described in the illustration below. 3.
9. ALT 3/4 output jacks: These are unbalanced ¼” phone type output jacks on which the output signal of the ALT 3/4 bus is available. These jacks can be used to connect to the input jack of an MTR, external mixer or other such device. 10. Main L/R output jacks: On these jacks is the main stereo output signal available. These jacks can be used for connecting the power amplifier which is used to drive your main speaker system.
Connections and Connectors Rear panel connections 1. AC adaptor in connector: Connects to the included PA-M1224 power adaptor. NOTE: Only use the original included PA-M1224 power adapter. The use of a different power adapter may cause damage to the appliance, or can even cause fire or electrical shocks. 2. Power switch: Use this switch to turn the mixer ON and OFF. 3. Main balanced L/R output: The main stereo output signal of the mixer is available on these 3-pin balanced XLR connectors.
Points to remember In all cases, always use high quality twin screened audio cable. Check for instability at the output. Always connect both conductors at both ends, and make sure that the shield is connected only at one end. Don’t disconnect the mains earth from each piece of equipment. This is needed to provide both safety and screen returns to the system star point.

4 Chapter Applications Setup procedure 1. Before connecting the microphones and instruments, be sure that all devices are turned off. Also be sure that all of the mixer’s channel faders and master control faders are set all the way down. 2. For each connection, connect one end of the cable to the relevant microphone or instrument, and connect the other end to the appropriate input jack on the mixer.
