FIRST OF ALL, WE WOULD LIKE TO THANK YOU AND CONGRATULATE YOU TO YOUR PURCHASE OF A ELECTRO-VO ICE POWER MIXER. The design of the PSX compact power mixers is based on decades of experience, research an d development as well client inter-communi - cation in the professional audio market.
1 . MIC Electronically balanced XLR-type inputs for the connection of low impedance microphon es, like the ones that are featured in big studio -and live mixing consoles. This type of input stage provides extra ordinary low- noise signal amplification with extremely low distortion (typical <0.
If you want to use this socket as a DIRECT OUT (Pre EQ), the stereo phone plug’s tip and ring ha ve to be short circuited, so that the audio signal is not interrupted. If you are using a monaural phone p lug instead, you will get a DIRECT OUT with breaker function – the signal flow within the channel is interrupted.
7. EQ SECTION The mixer’s EQ section allows shaping of the audio signal within different frequency ban ds. Turning one of the EQ level controls to the right enhances/amplifies the corresponding frequency range whil e turning them to the left lowers/attenuates the signal of the specific frequency band.
9. AUX 3 The AUX 3 control is primarily meant for the monitor mix. Nevertheless, when the master se ction’s AUX3 POST button is pressed, it can also be used as a third FX send bus. In that case, the signal is split post-fader and outputted via the AUX 3 send jack.
Since most features of the stereo inputs are virtually identical to those of the monaural inputs, we will not discuss their functions in detail again. Thus, we only point out the differences and ask you to refer to the paragraphs in the first chapter of this owner’s manual.
18. EQ SECTION The mixer’s EQ section allows very differentiated shaping of the incoming audio signal w ithin miscellaneous frequency bands. Turning one of the EQ level controls to the right enhances/amplifies the co rresponding frequency range while turning them to the left lowers/attenuates the signal of the specific frequenc y band.
FX1/FX2 The PSX offers two independent, identically-configured 18-bit stereo effect units – FX1 a nd FX2. Each unit provides 99 program presets which are selected by the use of the UP/DOWN buttons. The preset s are divided according to the different effect types into seven different groups which are sho wn on the printed labels.
30. FX ON These switches are used to turn the internal FX units on – the green LED is lit. Please keep in mind that you also can use an external foot switch to turn the FX units on. In this case the LED also shows the actual state of operation. If you want to use a foot switch, the FX ON switch has to be engag ed first.
Typically, the AUX3 channel is used as monitor bus. Depending on the setting of the AUX3 PO ST switch, it is also possible to configure the bus for the connection of an additional, external FX unit.

49. MAIN INSERTS Stereo phone jacks for the left and the right channels with breaker function. The low imped ance output is assigned to the tip (send) and the high impedance input (return) is assigned to the ring o f the connector. This jack allows the connection of external EQs, compressors, limiters, etc.
55. POWER AMP STATUS indicators These indicators inform you about the momentary operational status of the PSX’s intern al power amplifier. The POWER ON indicator is always lit when the PSX is in operational mode. If the LED is not lit after you have turned the power on, please make sure that the PSX’s power cable is correct ly plugged in.
The frequency ranges and the characteristics of the of the equalizer were carefully chose n for live sound. If you want a clear and intelligible sound, which also provides cymbals an d other instruments with added high frequency detail, you should raise the levels of the 8kHz or 16kH z bands a bit.
.
CABLING The ac power cord comes with the PSX. The quality of all other cables are your responsibili ty. Carefully chosen high quality cables are the best precaution to prevent problems during operation. The following wiring alternativ es are recommended to provide a trouble free operation of your setup.
In this chapter we would like to explain how to install a typical sound reinforcement syste m in passive configuration and incorporating stage monitor speakers.
• Pull all faders down and engage the PSX’s STANDBY button to prevent unwanted feedback. • First, switch the PSX on and then the external amplifier. • In case you have condenser microphones connected to the PSX, you can now turn on the phantom power by pressing the PHANTOM switch.
MAIN MIX • Position the master faders in the range between –30dB and –20dB. • Establish a basic mix, using the channel faders, so that the individual sound levels relat e to each other according to your personal taste. • The best range for the channel faders to be set to is in the area of –5dB to 0dB.
All inputs and outputs in the master section are referred to as the MASTER PATCHBAY. The mixer’s LINE OUTPUTS, RETURNS, and INSERTS are found here. To provide you with a wide vari ety of connection .
3. Using the internal power amplifier for monitoring or side-fill purposes: In case you want to use an external power amplifier to drive your main speaker systems, the internal power amplifier can be used for monitoring or side-fill purposes.
5. Maximum amount of speakers in a passive configuration: The PSX allows connection of up to three loudspeaker cabinets with an impedance of 8 ohms per channel. In other words: the internal power amplifier is capable of driving a maximum of six 8 ohm speaker models.
Technical Specifications PSX Mixing desk in rated condition, Unity Gain ( MIC Gain 20 dB ), all faders position 0 dB, a ll pots in mid position, Master fader + 6dB, amplifier rated output power into 8 ohms, one channel driv en, unless otherwise specified.
