The rear panel features comprehensive connectivity options including balanced XLR and 1/4-inch TRS inputs, barrier strip inputs, Speakon outputs, and binding post outputs. It also houses the circuit breaker and a bank of DIP switches for configuring operational modes such as stereo, parallel, bridge, clip limiting, and low-frequency filters.
4. نصب او تنظیم کول
4.1 د ریک نصب کول
The RMX2450a is designed for standard 19-inch equipment rack mounting. Ensure the rack is sturdy enough to support the amplifier's weight (approximately 44.4 lbs). Leave at least one rack space (1.75 inches) above and below the amplifier for proper ventilation, especially in enclosed racks.
4.2 آډیو ارتباطات
- معلومات: Connect your audio source (mixer, processor) to the amplifier's input connectors. The RMX2450a accepts balanced XLR, 1/4-inch TRS, and barrier strip inputs. Use high-quality shielded cables to minimize noise.
- پایلې: خپل سپیکرې د دې سره وصل کړئ amplifier's output connectors. The amplifier provides Speakon and binding post outputs. Ensure correct polarity and impedance matching between the ampلایفیر او سپیکر.
4.3 د بریښنا نښلول
سره وصل کړئ amplifier's power cord to a grounded AC power outlet. Verify that the power outlet's voltage سره سمون خوري amplifier's specified operating voltage. Ensure the power switch on the front panel is in the 'OFF' position before connecting to AC power.
5. عملیات
5.1 بریښنا کول / بندول
- Ensure all connections are secure and gain controls are set to minimum.
- Flip the front panel power switch to the 'ON' position. The power LED will illuminate.
- To power off, set gain controls to minimum and flip the power switch to 'OFF'.
5.2 د سمون ترلاسه کول
Use the individual channel gain controls on the front panel to adjust the output level of each channel. Start with minimum gain and slowly increase to the desired listening level, monitoring the signal and clip LEDs.
5.3 Mode Switches (Rear Panel)
The RMX2450a features DIP switches on the rear panel to configure various operational modes:
- سټریو حالت: Each channel operates independently, receiving its own input and driving its own speaker.
- موازي حالت: A single input signal drives both amplifier channels, which then drive separate speakers.
- د پل حالت: دواړه amplifier channels are combined to deliver maximum power into a single, higher impedance speaker. Consult the specifications for minimum impedance in bridge mode.
- Clip Limiters: User-defeatable clip limiters reduce distortion by preventing the amplifier from being overdriven. It is recommended to keep these engaged for speaker protection.
- Low-Frequency Filters: Selectable 30 Hz or 50 Hz low-frequency filters protect speakers from damaging sub-sonic frequencies and increase amplifier headroom.
6. ساتنه
- پاکول: بهرنۍ برخه پاکه کړئ ampد نرم او وچ ټوکر سره د پاکولو ماشین پاک کړئ. د مایع پاکوونکو یا محلولونو څخه کار مه اخلئ.
- وینټیلیشن: Regularly check that the ventilation grilles are free from dust and debris to ensure proper airflow and prevent overheating.
- اړیکې: Periodically inspect all audio and power connections for tightness and corrosion.
