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. When condenser microphones are connected, you have to press the PHANTOM button which is located in the master

section. The microphone gets its operational voltage (+24Vdc) through the mixer so you can forget about battery replacement .

CAUTION: Make sure to always connect the microphones before turning on

the phantom power or switching the PSX on with phantom power activated. This is the only way to prevent your microphones from damage. Also be sure to engage the stand-by button in the master section to prevent nasty power-on transients.

The connection of condenser type microphones and dynamic microphone models at the same time is possible and should generally not lead to any problems. Before you do so, please refer to the microphone’s manual to make sure that this kind of operation is in accordance to the manufacturer’s guidelines.

The MIC input is designed for levels between –60dBu … +11dBu – depending on the setting of the corresponding gain control. Because of their low impedance design and the phantom power these XLR-type inputs are not meant for cascading other mixing consoles or the connection of FX units, keyboards or other electronic equipment. When connecting this type of equipment, please use the LINE level inputs.

2. LINE

Electronically balanced inputs for the connection of electronic instruments, such as keyboards, drum machines, electric guitars and basses with active outputs, as well as all other high-level signal sources, like additional mixers, FX units, CD players, etc.

The LINE input is designed for levels between –40dBu and +30dBu. The connection of balanced or unbalanced signal sources is handled with monaural or stereo phone plugs, wired according to the diagram below. If the device that you want to connect has a balanced output stage, the use of balanced cables with stereo phone plugs is preferable. This type of connection greatly lowers the induction of external noise or HF interference.

Do not connect signal sources to the MIC and the LINE inputs at the same time, since the signals would interfere with each other, resulting in level reduction.

One more note: Please, do not connect electric guitars or basses with passive, high impedance outputs directly to one of the LINE inputs. The LINE inputs of the PSX – like the line level inputs of mixers from all other manufacturers – are meant for the connection of relatively low source impedance of electronic instruments or audio equipment. The reproduction of the instrument’s original sound characteristics will be unsatisfactory – unless this effect is intended. Those instruments should be connected using a special transformer, direct box or pre-amplifier with very high input impedance. Musical instruments that are equipped with an active electronic output stage (battery powered) can be connected without problems.

When connecting signal sources, please make sure that the corresponding channel faders or the master faders are at their minimal settings or that the STANDBY button is engaged. This will save you, your audience, and speakers from unpleasant pop noise.

3. INSERT

Stereo phone jack with breaker function. The low impedance output is assigned to the tip (send) and the high impedance input (return) is assigned to the ring (body). This jack allows the connection of external compressors, limiters, EQs, etc. into the corresponding channel’s signal path. The insertion point is post gain controls, low-cut filters, and voicing-filter stage and pre-EQ section and faders. You have to use a stereo phone plug wired according to the following diagram – in case you intend to use this jack as a true insert bus.

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.
