Enstalasyon
1. Montaj etajè
The EPQ304 is designed for standard 19-inch rack mounting and occupies 1U of rack space. Ensure adequate ventilation around the unit, especially if mounting other heat-generating equipment nearby. Do not block the ventilation grilles on the front and sides of the amplifier.

2. Koneksyon
Asire w la amplifier is powered off before making any connections. The EPQ304 features XLR, 6.35mm jack, and RCA input connectors, and Speakon-compatible output connectors.
- Koneksyon Antre: Konekte sous odyo ou a (miksè, pre-amplifier, etc.) to the input jacks on the rear panel. The amplifier supports balanced XLR, unbalanced 1/4" TRS, and RCA inputs.
- Koneksyon Sòti: Connect your loudspeakers to the Speakon-compatible output connectors. Ensure correct polarity and impedance matching. The EPQ304 is optimized for 4-Ohm and 8-Ohm loads.
- Koneksyon pouvwa: Connect the supplied power cable to the AC inlet on the rear panel and then to a suitable power outlet.

Enstriksyon Operasyon
1. Powering On / Off
Press the illuminated power button on the front panel to turn the amplifier on or off. It is recommended to turn on your amplifier after all other audio equipment and turn it off before other equipment to prevent pops or thumps through your speakers.
Figure 5: Illuminated power button on the front panel.
2. Level Controls and Indicators
Each of the four channels has an independent level control knob and LED indicators for signal presence, clip, and limit. Adjust the level controls to achieve the desired output volume. The clip indicator illuminates when the signal is too high and causing distortion. The limit indicator shows when the built-in limiter is active, protecting your speakers from excessive peaks.

3. Accelerated Transient Response (ATR) Technology
The EPQ304 incorporates Behringer's ATR technology, designed to provide rapid response to transient signals, resulting in crisp and clear audio reproduction, especially for percussive sounds and dynamic passages.
Antretyen
The Behringer EPQ304 requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Netwayaj: Sèvi ak yon twal mou, sèk pou netwaye eksteryè a ampPa sèvi ak pwodui netwayaj likid oswa solvan.
- Vantilasyon: Regularly check that the ventilation grilles are free from dust and debris. Blocked vents can lead to overheating and potential damage.
- Depo: Si w ap estoke aparèy la pou yon peryòd tan pwolonje, asire w ke li nan yon anviwònman ki sèk e ki pa gen pousyè.
Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Pa gen pouvwa | Power cable disconnected; Power outlet faulty; Internal fuse blown | Check power cable connection; Test power outlet; Contact qualified service personnel for fuse replacement. |
| Pa gen pwodiksyon son | Input cables disconnected/faulty; Output cables disconnected/faulty; Level controls set too low; Source device not sending signal | Verify all cable connections; Increase level controls; Check audio source. |
| Distorted sound / Clip LED constantly on | Siyal antre a twò wo; Amplifier overloaded; Speaker impedance mismatch | Reduce input signal level from source; Ensure speakers are within recommended impedance range (4-8 Ohms). |
| Amplifier overheats / Shuts down | Insufficient ventilation; Excessive load; Prolonged high-level operation | Ensure clear airflow around the unit; Reduce volume or load; Allow unit to cool down. |
Si pwoblèm nan pèsiste apre ou fin eseye solisyon sa yo, tanpri kontakte sèvis kliyan Behringer oubyen yon teknisyen sèvis kalifye.
