Pronomic TL-400 Power Amp 2x 1000 Watt

The Pronomic TL Series Power Amp is the match winner for use in all kinds of PA systems!

By consistently avoiding unnecessary technical gimmicks, this series achieves an incredibly affordable price while maintaining high sound and build quality. The power amp is just as interesting for musicians as it is for permanent installations, studios, and rental. All commonly required power classes are offered. So even powering power-hungry subwoofers with models up to 2x 2400 Watt is no longer a problem.

All important protection circuits are naturally integrated:

• The power soft-start function prevents overloading the power grid when switching on the power amp.
• The output DC protection constantly checks for DC components at the speaker outputs and switches off the outputs if signals are poor. This reliably prevents damage to speaker coils caused by excessive DC components.
• The integrated "true" clip limiter reliably prevents amplifier overload. The limiter stops DC components from forming in the circuit. It can be switched off if needed, e.g., when used with digital controllers.
• The "Noise Free On Off Circuit" prevents turn-on and turn-off noises, e.g., during power outages.
• Standard protection circuits like short-circuit protection are a given and naturally included here as well.
• All protection circuits constantly check if the fault still exists and immediately re-enable the outputs after the fault is cleared.

Always Everything in View

Despite the low price, exemplary display equipment was not skimped on:

• The power LED shows whether the power amp is on or off.
• The signal LED shows if audio signals are present at the inputs.
• The clip LED lights up when the amplifier is fully loaded.
• The protect LED signals a fault condition, causing the amplifier to shut down. It also lights during power-on tests before the outputs are enabled.
• Even the operating mode "Mono Bridge" or "Parallel Inputs" is clearly indicated on the front panel. This makes accidental and potentially dangerous bridging operation immediately recognizable.

Maintenance-Friendly and Durable Circuit Design

The meticulously thought-out design ensures smooth operation over many years:

• The cooling channels are acoustically optimized to keep the amplifier's self-noise as low as possible. The fans are, of course, controlled by temperature sensors.
• All power connections are excellently soldered, wired, and generously dimensioned. This greatly increases the lifespan of thermally stressed components.
• The centrally installed toroidal transformer ensures even weight distribution. It is mounted extremely solidly to suppress transformer vibrations.
