An Amp Designed to Complement the DAP-Xi Range
The DAP Qi-4400 was designed as a coherent amplification solution for the DAP-Xi speaker series, with power reserves suited to multi-speaker configurations. Its 1U format (44 mm height) and performance-oriented design make it a natural choice for fixed installations as well as mobile systems that need to remain reliable, compact, and quick to deploy.
Who Is It For and What Are Its Uses?
With its 4 channels, the Qi-4400 targets service providers, DJs, bands, venues, and integrators who want to manage multiple zones (left/right + monitors, delays, fills) with a single amplifier. It is also well suited for mobile racks: its lightweight facilitates transport, while its built-in protections secure operation during events where conditions may vary (temperature, wiring, handling).
Features and Key Points for Smooth Operation
Multi-channel Power and Bridge Mode
In stereo, each channel can deliver 400 W at 4 Ohms or 250 W at 8 Ohms (RMS), offering good flexibility depending on the number of speakers and total impedance. For more demanding needs on two lines, the Bridge mode allows 2x 800 W at 8 Ohms (RMS), useful for powering more demanding speakers or dedicated channels.
XLR Connectivity and Mode Selection
The Qi-4400 offers 4 XLR inputs and allows selection between Bridge and Stereo modes. This approach simplifies integration into a standard sound system, whether you are working with multi-output mixing, a distribution processor, or a console with dedicated sends.
LED Indicators and Gain Controls per Channel
Each channel features its own gain control, useful for precisely balancing levels between different speakers or zones. The signal, limit, and protection LEDs provide immediate feedback on activity: you monitor the level, anticipate clipping via the limit indicator, and quickly identify a protection mode in case of anomalies.
Built-in Protections for Reliability
Designed for intensive use, the amplifier includes several safeguards: short circuit, overheating, power on/off, DC voltage protection, and RF protection. The result: more stable operation and reduced risk of unexpected shutdowns or equipment damage in case of incidents on site.
