Buy & Import Professional Power Amplifier P-3122 CLASS H 3U from Lannge Electronic Co., Ltd. - Wholesale Supply

The Professional Power Amplifier P-3122 CLASS H 3U is a rack‑mount unit built for high‑efficiency audio reinforcement. It delivers 1200 W per channel into 8 Ω in stereo mode and 3600 W in bridge, covering 20 Hz - 20 kHz with a flat ±0.2 dB response. Total harmonic distortion plus noise is limited to 0.1 % and the signal‑to‑noise ratio reaches 102 dB. The chassis combines a brushed aluminium front panel with a steel frame, and the net weight is 35.73 kg.

The front panel aluminium alloy provides corrosion resistance, while the steel chassis meets the IEC 60204‑1 safety standard for industrial audio equipment. Internally the amplifier uses a two‑tier Class H topology, a high‑power toroidal transformer and original Toshiba audio tubes, a configuration commonly found in professional touring rigs. Typical power amplifiers in this class operate with a damping factor above 200 and a slew rate exceeding 20 V/µs, matching the P‑3122’s specifications. The unit incorporates an intelligent variable‑speed fan that adjusts cooling flow according to load, a feature standard in modern high‑output rack gear.

The P‑3122 is suited for large‑venue PA systems, concert stages, recording studios and permanent installations such as conference centres. System integrators and AV distributors often request a single‑unit carton, with dimensions 612 × 580 × 195 mm and gross weight 40.73 kg. The listing does not disclose minimum order quantity, price or lead time; interested importers should contact Lannge Electronic Co., Ltd. to confirm these details and discuss Incoterms and payment conditions.

Frequently Asked Questions About Professional Power Amplifier P-3122 CLASS H 3U from Lannge Electronic Co., Ltd.
The amplifier provides 1200 W per channel in 8 Ω stereo mode, as stated in the specification sheet.

Sourcing Professional Power Amplifier P-3122 CLASS H 3U from Lannge Electronic Co., Ltd. - China Import Guide

Potential buyers should first confirm that the amplifier complies with relevant safety and electromagnetic compatibility standards. Request a copy of the CE test report or any applicable international certification, and confirm that the unit has passed a factory acoustic performance test. Because the supplier does not list its own quality‑assurance documentation, buyers should ask for the latest inspection certificate and a detailed spec sheet matching the figures above.

Discuss logistics early to avoid delays. The unit ships in a single carton measuring 612 × 580 × 195 mm, with a gross weight of 40.73 kg, which fits standard 20‑foot containers. Confirm the Incoterm - typically FOB Enping or CIF Shanghai - and agree on payment terms such as T/T in advance or L/C at sight. As the response rate is currently zero, establish a clear point of contact for order confirmation.

Plan for quality verification on arrival. Engage a third‑party inspection agency to test THD+N, output power and protection functions against the supplied specifications. Request the original test report, a compliance declaration and the packaging list. Retain the shipping documents, including the commercial invoice and packing list, to facilitate customs clearance and warranty claims.
