Mono and subwoofer amplifier with switchable modes

The LORDWORLD G2 operates as a mono channel amplifier or a dedicated subwoofer amplifier. A mode switch selects between SUB and PBTL configurations. Two units can be paired for left and right channels without inter-channel interference. The package includes a 19V 4.74A power supply.

Four-step gain control

Gain is selectable at 20, 26, 32 or 36 dB to match source levels without added resistor colouration. A bass cutoff frequency knob sets the low-pass point for subwoofer integration. The TI TPA3116 and NE5532 op-amp circuit delivers 100 W with no audible background noise and includes speaker protection.

Passive subwoofer or mono speaker required

This amplifier has no built-in speaker and no wireless or streaming function despite the category label. Verify that your passive subwoofer or mono speaker matches the output capability. Confirm you have a mains outlet for the supplied 19 V supply and sufficient ventilation for the chassis.

Questions about this item

How often will the 19 V 4.74 A power supply need replacing?

The external 19 V 4.74 A supply is a standard replaceable unit; swap it only if it fails or the connector wears out.

What limits continuous output before the TI TPA3116 chip throttles?

Thermal protection on the TPA3116 kicks in first; sustained 100 W into 4 Ω will trigger it unless the chassis stays cool.

Does the built-in fan stay quiet when the amp runs all day at 100 W?

There is no fan; the passive heatsink stays silent, though the case gets warm during extended high-power use.
