INTRODUCTION FIRST OF ALL, WE WOULD LIKE TO THANK YOU AND CONGRATULATE YOU TO YOUR PURCHASE OF A ELECTRO-VOICE POWER MIXER. The design of the PSX compact power mixers is based on decades of experience, research and development as well client inter-communication in the professional audio market. With the PSX you own a power mixer that offers a wide range of functionality in a very compact frame. All the troubling experiences with cabling and matching mixers, amplifiers, FX units, and equalizers is history.
INPUT/MONO 1. MIC Electronically balanced XLR-type inputs for the connection of low impedance microphones, like the ones that are featured in big studio -and live mixing consoles. This type of input stage provides extraordinary low- noise signal amplification with extremely low distortion (typical <0.002%) even in the high frequency range. Generally, any type of microphone can be connected as long as its pin assignment is in accordance with the diagram shown aside.
INPUT/MONO If you want to use this socket as a DIRECT OUT (Pre EQ), the stereo phone plug’s tip and ring have to be short circuited, so that the audio signal is not interrupted. If you are using a monaural phone plug instead, you will get a DIRECT OUT with breaker function – the signal flow within the channel is interrupted. DIRECT OUT 4. GAIN Rotary control to adjust the MIC/LINE inputs’ sensitivity. These controls let you optimally adjust the incoming signals to the mixer’s internal operation level.
INPUT/MONO 7. EQ SECTION The mixer’s EQ section allows shaping of the audio signal within different frequency bands. Turning one of the EQ level controls to the right enhances/amplifies the corresponding frequency range while turning them to the left lowers/attenuates the signal of the specific frequency band. Before you begin to alter the sound, all EQ controls should be set to their neutral position; that is: their detented, center position. Try to avoid setting the EQ controls to extreme positions.
INPUT/MONO 9. AUX 3 The AUX 3 control is primarily meant for the monitor mix. Nevertheless, when the master section’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. To establish a monitor mix you can choose between two alternatives. The main difference being the point where the signal is split according to the setting of the AUX3 POST button.
INPUT/STEREO 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. 14. MIC Like their monaural counterparts the stereo input channels of the PSX incorporate extensive circuitry and electronically balanced XLR-type connectors for the connection of low impedance microphones.
INPUT/STEREO 18. EQ SECTION The mixer’s EQ section allows very differentiated shaping of the incoming audio signal within miscellaneous frequency bands. Turning one of the EQ level controls to the right enhances/amplifies the corresponding frequency range while turning them to the left lowers/attenuates the signal of the specific frequency band. Before you begin to alter the sound, all EQ controls should be set to their neutral position; that is: their marker points straight up (locked in place).
EFFECT 1/2 FX1/FX2 The PSX offers two independent, identically-configured 18-bit stereo effect units – FX1 and FX2. Each unit provides 99 program presets which are selected by the use of the UP/DOWN buttons. The presets are divided according to the different effect types into seven different groups which are shown on the printed labels. The programs within each preset group are sorted in ascending order where higher numbers provide the same FX type with increased intensity.
EFFECT 1/2 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 engaged first. The corresponding FX unit is activated and you can use the foot switch to turn the selected effect program on or off. 31.
AUX 3 Typically, the AUX3 channel is used as monitor bus. Depending on the setting of the AUX3 POST switch, it is also possible to configure the bus for the connection of an additional, external FX unit. 33. AUX3 SEND This output is meant for the connection of an external FX unit, a power amplifier or active stage monitor speaker systems, when the AUX3 bus is used for monitoring purposes. Using the AUX3 fader, the output level can be adjusted over a wide range up to +20dBu.
MASTER 49. MAIN INSERTS Stereo phone jacks for the left and the right channels with breaker function. The low impedance output is assigned to the tip (send) and the high impedance input (return) is assigned to the ring of the connector. This jack allows the connection of external EQs, compressors, limiters, etc. into the master L/R signal path. The insertion point is pre-master faders. As with the inserts of the monaural input channels, different DIRECT OUT functions can be accomplished.
MASTER 55. POWER AMP STATUS indicators These indicators inform you about the momentary operational status of the PSX’s internal 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 correctly plugged in. If this is the case and the LED is still not lit, please contact your dealer.
MASTER The frequency ranges and the characteristics of the of the equalizer were carefully chosen for live sound. If you want a clear and intelligible sound, which also provides cymbals and other instruments with added high frequency detail, you should raise the levels of the 8kHz or 16kHz bands a bit. If the mids sound too nasal, you should attenuate the 1 kHz and 2.5 kHz frequencies a few decibels.
STANDARD INSTALLATION CABLING The ac power cord comes with the PSX. The quality of all other cables are your responsibility. Carefully chosen high quality cables are the best precaution to prevent problems during operation. The following wiring alternatives are recommended to provide a trouble free operation of your setup.
STANDARD INSTALLATION In this chapter we would like to explain how to install a typical sound reinforcement system in passive configuration and incorporating stage monitor speakers.
STANDARD INSTALLATION • 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. • Activate the PSX’s by pressing the STANDBY button again. SOUND CHECK • First, adjust the input levels of the microphones that are connected to the PSX. Please proceed as follows: 1.
STANDARD INSTALLATION 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 relate 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. In this way you are provided with enough tolerance for later adjustments. • Use the master faders to adjust the overall volume.
MASTER PATCHBAY AND INSTALLATION ALTERNATIVES 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 variety of connection possibilities, the MASTER INSERTS, MAIN OUTPUTS, EQ INPUTS and EQ OUTPUTS, POWER AMP INPUTS, and the AUX SENDS and AUX RETURNS can be independently connected with each other or routed to external devices.
MASTER PATCHBAY AND INSTALLATION ALTERNATIVES 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. Use short patch-cables to connect the AUX3 OUTPUT with the EQ INPUT L and the MONO OUTPUT with the EQ INPUT R.
MASTER PATCHBAY AND INSTALLATION ALTERNATIVES 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. The following diagram shows how the speakers have to be connected. 6. Active stereo 2-way configuration: In this example the internal power amplifier of the PSX is used to drive the Hi/Mid cabinets.
SPECIFICATIONS Technical Specifications PSX Mixing desk in rated condition, Unity Gain ( MIC Gain 20 dB ), all faders position 0 dB, all pots in mid position, Master fader + 6dB, amplifier rated output power into 8 ohms, one channel driven, unless otherwise specified.
