Studio amplifier Omnitronic PKD-352 — Class-D, 350W RMS

Omnitronic PKD-352 is a Class-D studio amplifier that delivers 350W RMS of continuous power in a compact package. Engineered for professional audio environments, the amplifier combines high efficiency with reduced heat generation and a small footprint. The unit is intended for driving studio monitors and small PA systems, offering stable amplification for rehearsal, recording, monitoring and other near-field or small-venue applications.

Advantages

The Class-D design provides high conversion efficiency, resulting in lower power draw and reduced thermal stress compared with traditional linear amplifiers. Its 350W RMS output ensures consistent power delivery for active monitors or passive speakers within the amplifier’s recommended impedance range. The compact housing and efficient cooling allow flexible rack or shelf placement in tight studio setups. Front and rear panel controls and connections give straightforward integration into existing audio chains.

Suitable for

• Driving nearfield studio monitors in project and home studios
• Powering small PA systems for rehearsal rooms or small venues
• Live monitoring and foldback systems for musicians and engineers
• Fixed installations where compact, efficient amplification is required

Key specifications

• Amplifier class: Class-D
• Continuous output power: 350W RMS (total or per channel depending on configuration)
• Intended load: compatible with common studio monitor and small PA speaker impedances
• Cooling: passive/efficient thermal design suitable for compact installations
• Form factor: compact chassis for rack or shelf mounting

How to use

Connect the amplifier to a suitable audio source using balanced or unbalanced line-level outputs from your mixer, audio interface or preamplifier, following the input type supported by the unit. Match speaker impedance and power handling to the amplifier’s specifications to avoid overloading speakers. Set input gain and output levels at low to moderate settings before powering up, then increase to the required monitoring level while listening for distortion or clipping. Provide adequate ventilation around the amplifier and avoid obstructing airflow from vents.

Usage recommendations

Use appropriate speaker cables with secure connectors and verify polarity before extended operation. For reliable long-term performance, allow for cooling clearance, avoid sustained maximum-output operation, and perform regular visual inspections of connections and mounting. When integrating into a rack, use vibration-isolating mounts if the amplifier will be moved frequently.
