The Anthem Statement P2 is a two-channel power amplifier enclosed in a solid and massive aluminum housing. The design of the device implies the complete independence of the "monoblocks" located inside.
The P5 five-channel amplifier from the Anthem Statement line can be attributed to the elite of the high—end, both in terms of performance and the level of technology embedded in them. They even look professional — huge, black, with curved pads on the sides of the front panel, reminiscent of mount rack staples. However, despite the industrial design, this monster is not without grace, mainly due to the filigree treatment of aluminum surfaces.
The Anthem MCA 225 GEN 2 is a two-channel power amplifier. It consists of custom low—noise toroidal transformers and high-quality filtering capacitors in the power supply, enlarged aluminum radiators and a patented automatic on/off circuit. To reduce the output load, eight paired bipolar transistor assemblies operate in each channel of the CA GEN2.
The Anthem MCA 325 GEN 2 is a three-channel power amplifier. It consists of custom low—noise toroidal transformers and high-quality filtering capacitors in the power supply, enlarged aluminum radiators and a patented automatic on/off circuit. To reduce the output load, eight paired bipolar transistor assemblies operate in each channel of the CA GEN2.
The manufacturer claims a record signal-to-noise ratio of 120 dB for the amplifiers. The power of each channel when operating on a load with a nominal resistance of 8 ohms is 225 watts, and when the impedance drops to 2 ohms, the amplifier is capable of developing up to 600 watts. In such a muscular amplifier, the proprietary Advanced Load Monitoring technology, which protects the speakers from clipping, will be very useful.
