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). Try to avoid setting EQ controls to extreme positions. Usually, minor changes are totally sufficient and produce the best results in the overall sound. You should use the natural reproduction as an orientation mark and rely on your musically trained ear to judge the sound quality. The moderate use of the MID control is the best remedy to avoid acoustical feedback. In this frequency range, you should try to avoid excessive enhancement. Lowering the level in this band will provide you with high amplification rates without feedback.

The HI and LO controls of the STEREO channels’ EQ section provide a degree of control that is equally adequate for LINE level inputs and microphones. The MID control is active in a comparably wide frequency band around 2.4 kHz. With most microphones this is the critical range, where a slight attenuation offers excellent results.

19. AUX/FX

These controls determine the amount of the summed L/R signal that is send to the AUX/FX bus. The signal routing is POST FADER. For more details on the functioning of these controls, please refer to the INPUT/MONO section of this owner’s manual.

20. AUX3

This control determines the amount of the summed L/R signal that is send to the AUX3 bus. Depending on the setting of the AUX3 POST switch within the PSX master section you can choose if the signal is routed PRE or

POST FADER.

21. BAL

The function of the BAL control of the stereo channels is equivalent to the PAN control’s function of the monaural channels. If you turn the rotary control all the way to the right, the signal is routed to the right output while the signal of the left channel is muted. When the control is set to its center position, the signal is present with equal intensity at the corresponding L/R outputs. Whenever stereo sound sources are connected to a stereo channel, you should leave the BAL control at the center position or make only minor adjustments in either direction. In case a microphone or another monaural sound source is connected, the BAL controls function absolutely identical to the PAN controls of the monaural input section.

22. PFL

Engaging the PFL button routes the audio signal of the corresponding input channel to the headphone bus where the stereo signal is outputted to the headphone output. You can route as many channels as you want to the bus at the same time. The volume levels of the individual signals are not affected by the setting of the corresponding channel faders – PRE FADER LISTENING. This gives you the opportunity to set the level and the EQ of a channel without the need to include it in the main mix.

23. SIGNAL/PEAK

For the stereo SIGNAL/PEAK indicator function, the left and the right channels are monitored separately. The respective highest level reading is indicated, assuring that neither one is already driven into clipping. For further descriptions on how to use this indicator most efficiently, please refer to paragraph 12 of the previous chapter.

24. VOLUME

The channel fader is used to simultaneously adjust both channels of the stereo signal. Functioning and specifica- tions are totally similar to the monaural channel fader, as previously described.

PSX1600, PSX1000, PSX2200 specifications

Electro-Voice, a prominent name in professional audio equipment, has developed a series of high-performance power amplifiers known as the PSX series, which includes the PSX2200, PSX1000, and PSX1600 models. These amplifiers are engineered to deliver exceptional power, clarity, and reliability, making them suitable for a variety of applications such as live sound, installations, and portable use.

The PSX2200 is the most powerful model in the PSX lineup, offering a robust output of 2,200 watts at 4 ohms. This amplifier is designed to handle demanding audio environments, providing headroom and performance necessary for large audiences. One of its key features is the Peak х-Over Limiting technology, which ensures that the amplifier delivers maximum power without distortion during peak performance. Additionally, the PSX2200 is equipped with built-in high-pass and low-pass filters, allowing users to tailor the sound to their specific needs.

The PSX1000 represents a mid-range option that still packs a punch, delivering 1,000 watts at 4 ohms. It is designed for versatility, making it ideal for a range of sound reinforcement applications. One standout feature of the PSX1000 is its Intelligent Clip Limiting system, which automatically adjusts the input signal to prevent clipping and maintain audio clarity. Moreover, the amplifier features a rugged chassis and intuitive interface, which enhances both durability and ease of use in various settings.

The PSX1600 serves as a bridge between the PSX1000 and PSX2200, offering 1,600 watts at 4 ohms. It incorporates advanced thermal management technology, ensuring stable performance even under demanding conditions. The PSX1600 is engineered for reliability, featuring extensive protection circuitry that safeguards against issues like over-temperature, short circuits, and signal overloads. This amplifier is particularly favored for its ability to maintain sound quality during prolonged use.

All three models in the PSX series share common characteristics such as a lightweight design, durable construction, and efficient power supply systems, making them highly portable and easy to integrate into existing sound systems. The PSX amplifiers are also equipped with comprehensive monitoring capabilities, including LED indicators that provide visual feedback on power and operational status.

In summary, the Electro-Voice PSX2200, PSX1000, and PSX1600 represent a powerful trio of amplifiers that offer versatility and reliability for professional audio applications. With their advanced technologies, user-friendly features, and impressive performance specifications, these amplifiers are well-suited to meet the demands of sound engineers and audio professionals alike.
