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.

The LIMIT indicator signals that you are operating the PSX at the internal amplifier’s limit. Frequent blinking of the LED is acceptable, since the amplifier’s incorporated limiter prevents serious distortion. Continuous illumination indicates that you should be aware of a degradation in sound quality. In that case, the master level should be reduced.

The PROTECT indicator is lit when one of the PSX ’s extensive protection circuits is guarding against thermal overload, HF-induction, DC at the outputs, or short circuits is activated. When the PSX is in protect mode, the speaker outputs are muted and the amplifier’s inputs are shorted to prevent the amplifier from being damaged. In this case you should first check to see if the ventilation louvres are blocked. Another cause could be that you have more than three 8 ohm speaker systems per output channel connected. You should also disconnect the SPEAKON output connectors and check the speaker cables for short circuits.

During normal power-on operation, the PROTECT LED always lights for about two seconds, signaling that the PSX’s protection circuitry is operational.

56. PHANTOM POWER

When this switch is engaged, all MIC inputs are supplied with +24V phantom power. Please make sure prior to engaging phantom power that the PSX is switched off or in stand-by mode. With active phantom power the connection of unbalanced signal sources (keyboards, mixer, etc.) to XLR inputs is not advisable, because this could lead to severe damaging of your equipment.

ATTENTION! IMPORTANT NOTICE!

In general, the operation of phantom-powered condenser microphones and balanced dynamic microphones at the same time does not lead to any problems. Nevertheless, some balanced dynamic microphones are extremely sensitive to this. Some models could get damaged when used on mixers with active phantom power. Please refer to the microphones’ owner’s manuals to make sure that this operation is permissible.

To be on the safe side, you should switch the PHANTOM POWER off, when using balanced dynamic microphones, only.

57. 7-BAND EQUALIZER

The respective EQ ON switches activate each 7-band graphic EQ within the PSX’s master section. The EQ’s insert point is post master fader and pre internal power amplifier. The EQ is bypassed when the EQ ON switch is not locked in its “ON” position. The two graphic EQs provide seven frequency bands, each. Through these faders you are able to match the overall sound optimally to the acoustic conditions of different locations or shape it according to your personal taste. Each frequency band allows ±10dB equalization in the corresponding range with a Q=1.4.

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.
