A true goliath!
High-performance power amplifier A 1560: This output stage combines enormous power with extreme broad-band characteristics for superb performance and speed. Equipped with High-End mica capacitors, ACT silver circuit boards, precision resistors and carefully optimised torroidal transformers this amplifier can boast the very finest components available, as well as the new OAD op-amp technology mentioned earlier. Added to these advantages are non-magnetic circuit boards, and non-magnetic materials for all connections and contacts, completely eliminating the disturbing distortion which is caused by ferro-magnetic non-linearity effects.

The ICA technology (Isolated Current Amplifiers) developed by T+A de-couples the input stages of the power amplifier from the current amplifier stages, and this design feature has also been further improved. The circuit features the latest transistors for the driver and output stages, with reduced gate capacitance and higher limit frequencies, giving the output stages an even greater bandwidth and higher speed. An important result of this technology is that the sound characteristics of T+A's output stages and integrated amplifiers are independent of the selected volume level and the load represented by the loudspeakers connected to them. It is no coincidence that many owners of impedance-critical and phase-critical loudspeakers use T+A amplifiers, since they possess enormous reserves of power - as well as simply sounding better under all conditions.

The output stages of the R-System
As is the case with the T+A pre-amplifiers, T+A have adopted a fundamental strategy relating to output stages; a strategy which is employed in all variants of these devices. The requirements placed on High-End power amplifiers in terms of sound quality have become enormously more exacting over the last few years. Neutrality, high output power and performance independent of load have always been required, but optimum dynamics and peak-handling characteristics have now gained greater importance. T+A's output stages fulfill these requirements to perfection. The input stages of T+A audio power amplifiers are de-coupled from the output stages. T+A terms term this technology ICA (Isolated Current Amplifier), and it ensures that T+A power amplifiers maintain their superb sonic qualities regardless of the loudspeakers connected to them.
T+A has developed a new and unique technology for the circuit boards used in the output stages. T+A's term for these circuit boards is ACT. Copper alone is usually employed for circuit boards, but T+A now also employ silver as conductor where the signal passes, with no separation layer.

The basic reason for this innovation is that silver is the best conductor available bar none, and offers outstanding sound qualities - especially in the high-frequency range. Since T+A amplifiers have very high limit frequencies (Ultra Wide Bandwidth), the skin effect also plays its part here. At crucial points in the new output stages T+A employ mica capacitors, as these have the lowest loss factor of all, plus silver electrical contacts and electrodes. These parts form a homogeneous system with the ACT circuit boards. At the same time these circuit boards are non-magnetic, and all connections and contacts are also designed to have the same properties, with the result that disturbing induced distortion effects are eliminated completely. All T+A output stages are matched accurately to each other in terms of amplification factors, dynamic characteristics and phase / group timing, making them absolutely ideal for bi-amping and multi-amping configurations.

The back panel connections of the A 1560 R
INPUT: Asymmetrical amplifier input with an input sensitivity of 1 Veff.
XLR: Symmetrical amplifier input (XLR) with an input sensitivity of 1.55 Veff.
SPEAKER A + B: Two pairs of loudspeakers can be connected (SPEAKER A and SPEAKER B). The impedance of each speaker must not fall below 4 Ohm (DIN rating).
CTRL: If the power amplifier is operated with an (optional) remote-controlled pre-amplifier (e.g. P 1220 R), then the CTRL IN socket should be connected to the pre-amplifier's OUT CTRL socket via the RZ 001 remote control lead.
RLink: Interface for future system expansions.
