POWERFUL 3.1-WAY FILTERED AMPLIFIER designed for TRI-AMPLIFY loudspeakers, with or without internal passive filters.

This amplifier is MONOPHONIC, 2 units are needed for stereo systems.
Robust and reliable construction, designed to provide years of excellent sound, with the most modern and efficient high-end audio circuits and components. Silver-plated loudspeaker connectors and cables, gold-plated double-thick copper main plate, tin / silver solder, anodized aluminum chassis, 10mm front and 3mm panels, stainless steel internal grille, no fan. Manufactured in Spain (EU).
It incorporates a CROSSOVER (filter) analog high resolution Linkwitz-Riley 4th order that separates the sound into 4 frequency groups. The internal passive filter of the loudspeakers will influence much less in the final response, obtaining much better sound and greater detail and resolution.

HIGH: from 2700Hz to 100Kz, for tweeters drivers.
MID:   from 250Hz to 2700Hz, for the middle drivers..
LOW: from 1 to 250Hz with the SUB switch at 0, or from 40 to 250Hz with the SUB switch at 1, for the woofer drivers.

IMPORTANT: These cut filters are universal, they have been optimized to work well with virtually all loudspeakers. NO COST ADDED you can indicate in your purchase the cutting frequencies that you need and we will send it to you personalized. A 2.1-way model is also available. You can request new frequencies in the future, with a moderate cost we send circuits with the new settings, easy to insert inside. This 3.1-way ampli can be updated with a reduced cost to version 2.1

LEVEL ADJUSTMENT: All channels are delivered factory adjusted to the same level, but the user can modify the output level of each channel with a small flat screwdriver, acting on the multi-turn potentiometers found on the rear panel marked with G ( general profit) H / M / L / S. By allowing this adjustment, you can perfectly optimize the overall response of the different speakers in the drivers and align them to personal needs. (view image)

POWER: We do not use power transformer, which are heavy, noisy, hot and inefficient. With a weight of 9Kg. incorporates 2 power supplies with total 1000W, high performance (over 90%), switched, specifically designed for audio, and capable of delivering fast and high peaks of more than 2000W point consumption. It uses a total of 12 regulated sources, and an extremely pure isolated regulation for the filtering circuits that keeps the noise levels at exceptional values.
The powerful Low channel delivers 400W continuous and the Mid 150W and the High 150W, at 4 ohms, with peaks that can double this power. They can handle 1 ohm impedances without difficulty. Very low distortion, excellent signal-to-noise ratio, unbeatable control and dynamics and low heat generated.
Together with the output circuits, it assembles large capacitors with 80,000UF of extra capacity, just where they are needed for fast transients, and with a soft start system so as not to overload the electrical network during the ignition.
Various sophisticated SERVO CIRCUITS constantly regulate the DC OFFSET (in the power output), maintaining DC levels below 2mV, always close to zero, necessary to achieve a high resolution and microinformation in the power outputs and prevent unnecessary heating in the power transistors.

A design WITHOUT microcontroller monitors the security parameters, indicating by the color of the light circle of the central switch the possible anomalies detected. Warns when it is at 90% power (close to clipping). Auto-off protection, in case of serious failure or excessive heating. Uncoupling and protecting loudspeakers on and off.

INPUTS, balanced XLR and RCA, 1Vrms for maximum power. The selection is made with the RCA switch (orange rear LED lit). Yes connect a standard 3.5mm jack. between amps in TRIGGER RCA, all will change at the same time. It can also be switched with a 12VDC signal in this connector, for example, from an AV receiver, integrating two different preamp systems into the amplifier.

HPF, (High Pass Filter) this switch activates a high-pass filter of 25Hz, useful to lighten the bass pressure, or in vinyl (subsonic) listeners.

SUB OUT RCA, to connect an active subwoofer, regardless of the position of the SUB switch (1/0), the frequency group will always be from 0 to 40Hz (or whatever you indicate).

SUB RCA MONO, connecting an RCA cable between two amplifiers, you get the mix of the two sub channels in mono. Exclusive function and very useful for a perfect configuration 3.1 with 1 or 2 subs.

REM POWER, (Remote Power On) when connecting a standard 3.5mm jack the ampli will remain in STANDBY until it receives a 12VDC signal. All must be connected in series, and will go on with a few seconds of delay between them so as not to recharge the domestic power line due to its high starting power.

GROUND, connects the chassis to a virtual earth or to the electrical network, can eliminate looping noises, but without losing the security provided by the ground connection.
