Прочие устройства — ToneWinner AD-5100PA+

The AD-5100PA+ is a 5-channel power amplifier made by Guangzhou Tonewinner Electronics, the Chinese maker of AV processors, receivers and speaker systems. It is meant for home theater setups where a processor or receiver with preamp outputs handles decoding and needs separate amplification for five speakers, and it also works in multichannel music systems. ToneWinner sums the unit up as a five-channel amplifier with five protection functions.

Key specs that matter

ToneWinner rates every channel at 100 W into 8 ohm and 140 W into 4 ohm, both at 1% THD and 1 kHz. The rated speaker impedance is 8 ohm. Frequency response is 20 Hz to 30 kHz within +1 and -3 dB. THD is 0.1% or lower, and S/N is 100 dB or better, both A-weighted. Total power consumption is given as 500 W or less. Weight is 9.6 kg. The chassis measures 431 x 352 x 130 mm and fits the usual full-width component format of home cinema racks.

Engineering and use context

Five independent signal indicators on the front show activity on each channel, and their brightness changes with the output level, so the owner can see at a glance which channels are active and how hard they are working. Heat is handled by an intelligent air cooling system rather than purely passive heatsinks, which helps in closed cabinets where natural airflow is limited. The five protection functions guard the amplifier and the connected speakers against fault conditions. Speaker connections use gold-plated terminals. The front panel is finished in polished aluminium, and the power supply adapts to mains voltages from 110 to 230 V, which allows the same unit to be used in different regions without an internal voltage switch. Inputs are analogue, and the noise specification refers to the analogue through path.

Pairing

A natural source is a ToneWinner AV processor or any AV receiver with preamp outputs, where the AD-5100PA+ can drive the front left, center, front right and two surround speakers of a 5.1 system while the receiver's own amplifiers run height or zone channels. Speakers of the rated impedance are the intended load, and lower-impedance models are also covered by the specified power. Since the amplifier has no subwoofer output of its own, the low-frequency channel stays with a powered subwoofer connected directly to the processor's LFE or sub output.

Alternatives

For layouts with more speakers, ToneWinner offers the AD-7300PA+, a Class AB design that drives seven channels from discrete mono modules.
