![[GRADE S] TOPPING ARPEGEAR HANE In-Ear Monitors IEM Dynamic 80 Ohm 115dB 5Hz-35kHz](https://www.audiophonics.fr/66633-thumb_default/topping-arpegear-hane.jpg)
Tonewinner AD-3240PA Power Amplifier 3x400W 8 Ohm
The Tonewinner AD-3240PA is a three-channel power amplifier designed to drive the front left, center and right channels of a home theater system. It delivers 250W into 8Ω and up to 400W into 4Ω per channel, thanks to an independent balanced architecture that reinforces the front stage and handles the significant level variations of multichannel soundtracks.
Intended for scalable home theater installations, it combines low-noise amplification, temperature-controlled cooling and five protection circuits to maintain stable operation during extended listening sessions. Its trigger functions also make it easy to synchronize power-on with a processor or other amplifiers, while its three independent channels allow it to be integrated into a 5.1.2 configuration as well as a more powerful multichannel system.
Tonewinner AD-3240PA: Independent amplification of the three front channels
The Tonewinner AD-3240PA is a three-channel power amplifier intended for the front left, center and right speakers of a home theater system. As these three channels concentrate more than 85% of the sound content, their separate amplification reinforces the front stage while preserving good clarity of dialogue and effects. Each channel delivers 250W into 8Ω and up to 400W into 4Ω, with a distortion of 1% at 1kHz.
The power stage adopts a balanced circuit of Hi-Fi design, developed to maintain a high signal-to-noise ratio from the source to the speakers. This architecture handles the significant level variations typical of movie soundtracks, keeping a stable reproduction when the system operates at high volume.
Tonewinner AD-3240PA: Signal indicators
Each channel has its own light indicator, whose intensity varies according to the level of the received signal. This indication allows the activity of the three channels to be monitored at a glance and facilitates checks during commissioning or troubleshooting of the installation.
Tonewinner AD-3240PA: Full protection
The AD-3240PA integrates five protection circuits that monitor operating conditions and possible usage errors, among other things. This monitoring limits the risk of damage related to overloads or unsuitable content, while allowing the amplifier to operate reliably during extended home theater sessions.
Tonewinner AD-3240PA: Temperature-controlled cooling
Its cooling system automatically adapts the fan speed to the internal temperature of the unit. Ventilation thus remains discreet when the thermal load stays low, then gradually increases when the requested power requires greater dissipation, which helps maintain the stability of the amplifier over time.
Tonewinner AD-3240PA: Trigger integration
The trigger inputs and outputs allow the power-on and shutdown of the AD-3240PA to be synchronized with a home theater processor or another power amplifier. This connection simplifies the management of a multichannel installation by consolidating the control of several units within a single chain.
