The 0.42 kg tabletop receiver (measuring 210 mm × 47 mm × 165 mm) is powered by an external 12V DC power adapter connected to a 220V–240V AC 50Hz source. Keep the power input jack and rear audio output terminals free of debris to maintain signal-to-noise performance at 100 dB and dynamic range above 90 dB.

Periodically inspect the 3-pin XLR individual balanced output sockets (0 dBu nominal) and the 6.35 mm (1/4-inch) unbalanced mixed phone jack (-10 dBu nominal) for mechanical wear or contact oxidation. Clean connector contact points with dry, residue-free electrical contact cleaner if hum or intermittent channel loss occurs. Ensure the front-panel rotary volume controls for Channel A and Channel B turn smoothly without physical resistance or potentiometer crackle.

RF Signal Optimization and Frequency Alignment

The Ahuja AWM-700U2 operates across eight factory-paired UHF channels using FM modulation. To avoid RF dropouts and signal interference:

Confirm that both handheld transmitters match their respective factory-assigned receiver channel frequencies on the front-panel frequency indicators.
Verify front-panel RF and AF LED indicators during sound checks to confirm steady carrier capture and clear audio throughput across the full 50 Hz to 15,000 Hz frequency response.
Maintain unobstructed line-of-sight between the dynamic handheld transmitters and the tabletop receiver, keeping the receiver clear of large metal obstructions or external high-power electromagnetic sources.

Dynamic Capsule and Physical Chassis Maintenance

The cardioid dynamic capsules require periodic visual and mechanical inspection. Wipe the exterior metal mesh and transmitter housing with a clean, dry, lint-free cloth. Do not allow liquids, cleaning sprays, or excessive moisture to penetrate the dynamic capsule element or internal circuitry. Keep the receiver chassis ventilation clear of dust accumulation to maintain optimal heat dissipation during long operational cycles.
