The compact and lightweight design also makes transportation, installation and deployment more convenient for mobile sound systems, stages and touring applications.

3. Powerful Amplification Performance

The DQX2-2000 provides high output power across its two channels, with the following published Stereo ratings:

2 × 1000W at 8Ω Stereo.

2 × 1700W at 4Ω Stereo.

2 × 2890W at 2Ω Stereo.

This output capability makes the amplifier suitable for professional loudspeaker systems. Its published 2Ω operation rating offers additional system configuration flexibility, although speaker impedance and wiring compatibility should always be checked before use.

4. High-Power Bridge Mode

In addition to Stereo operation, the StudioMaster DQX2-2000 supports Bridge mode, combining its two amplifier channels into a single higher-power output. The published Bridge ratings are:

2000W at 16Ω.

3400W at 8Ω.

5780W at 4Ω.

Bridge mode is useful for configurations that require greater power for a compatible loudspeaker or speaker group. Always follow the manufacturer's wiring instructions and impedance limits when using this mode.

5. Integrated DSP for Flexible Signal Processing

One of the key features of the DQX2-2000 is its built-in digital signal processor. The integrated DSP provides several tools for optimizing loudspeaker performance, including:

EQ: adjusts the frequency response.

Crossover: divides frequency bands between speaker groups.

Limiter: limits the output signal level.

Delay: aligns timing between loudspeakers.

Routing: configures signal distribution.

The integrated DSP can reduce the need for separate processing equipment in some system configurations while making setup and adjustment more convenient.

6. 3.3-Inch HD LCD Display

The StudioMaster DQX2-2000 is equipped with a 3.3-inch HD LCD screen, allowing users to view and manage device settings.

The integrated display provides convenient access to DSP functions and system configuration. It is particularly useful when technicians need to adjust settings directly at the equipment rack or installation location.

7. Ethernet Network Control and Monitoring

In addition to direct operation on the amplifier, the DQX2-2000 supports Ethernet Network Control according to the published product information. Network connectivity provides another way to control and monitor the amplifier through a compatible control system.

This feature can be useful in fixed installations and systems with multiple audio devices, where technicians need convenient access to system settings and adjustments.

8. Wide Frequency Response

The amplifier has a published frequency response of 20Hz to 20kHz. This range covers the common operating bandwidth of full-range sound systems, allowing the DQX2-2000 to work with a variety of loudspeakers.

Combined with its integrated DSP, users can adjust EQ, crossover and delay settings to better suit the loudspeaker characteristics and installation environment.

9. Signal Quality and Audio Control

According to the product specifications, the DQX2-2000 has a signal-to-noise ratio of at least 105dB, THD+N of 0.01% and a damping factor of 5000.

These specifications describe important aspects of the amplifier's signal performance and control characteristics. Together with the integrated DSP, they provide technicians with additional tools for configuring the sound system according to application requirements.

10. Class D Amplification and Switching Power Supply with PFC

The StudioMaster DQX2-2000 uses Class D amplifier technology according to the product description. This design aims to deliver high output power in a compact 1U rack enclosure.

The amplifier is also described as featuring a switching power supply with Power Factor Correction (PFC) and an operating efficiency of over 95%. Its wide input voltage range provides additional flexibility for use in different installation environments.

11. Balanced XLR Input Connectivity

The DQX2-2000 is described as featuring balanced XLR inputs for connection to mixers, signal processors and other professional audio equipment.

Balanced connections help reduce interference along the signal path, particularly in installations with long cable runs or multiple electronic devices.

12. Cooling and Protection System

According to the product description, the StudioMaster DQX2-2000 features an intelligent variable-speed cooling fan to help manage operating temperature.

The amplifier also includes the following protection functions:

Thermal: protects against excessive operating temperature.

Overload: protects against overload conditions.

DC Output: protects against DC voltage at the output.

Limiter: limits the output signal level.

These functions are designed to support stable amplifier operation and help reduce risks to the connected loudspeaker system during high-power use.

13. Applications of the StudioMaster DQX2-2000

With its two-channel amplification, integrated DSP and Ethernet control, the StudioMaster DQX2-2000 can be considered for a variety of professional sound applications:

Live stage sound systems.
