PSX is best equipped for universal use. No matter, whether on-stage, in a home recording environment or in a permanent installation, Electro-Voice’s PSX is the ideal partner to meet your expectations of a professional audio device - effective and reliable.
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.

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 –...

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;...

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.
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.

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;...
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.
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.
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.

CAUTION: Overload or short circuits can result from damaging this output. To prevent this from happening, we recommend the use of a Littlelite gooseneck lamp, available from your Electro-Voice dealer. For further information, please consult your dealer.
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.
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.
You can also consider the use of 4-wire cables where pins 2+ and 2- are also connected. This provides you with the possibility of using these cables with active 2-way system configurations, as well. Professional-quality speaker cables with SPEAKON connectors and all other cables, plugs, and sockets are available at your Electro-Voice dealer. LF-CABLES – BALANCED OR UNBALANCED? For all low current wiring , your best choice are balanced cables (2 signal conductors + ground shielding) with XLR-type connectors or with stereo phone jacks and plugs.

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. The necessary equipment is: 1 PSX 1 Power amplifier for the monitor signal Speaker Systems 2 Woofer cabinets Speaker stands or 2 pole mounts 2 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.
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.

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.

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.
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. Maximum Midband Output Power, 1 kHz, THD into 4 ohms into 8 ohms...
(d): malfunction resulting from misuse or abuse of the product; or (e): malfunction occurring at any time after repairs have been made to the product by anyone other than Electro-Voice or any of its authorized service representatives.
