Meridian 505 Mono Power Amplifier

The Meridian 505 Mono Power Amplifier has been designed to cater for two separate requirements: clarity and response, and it takes both of these in its stride.

The 505 can be used with the 502 or 501 preamps, or with the 568 Surround Controller. It matches perfectly with the 557 for centre-channel applications. For for the complete theatre approach 505 can be used in multiple sets.

Product/505 Power

 

The Meridian 505 houses one powerful amplifier in its mono construction. Rated at 160W into 8 ohms, the over-specified output stage uses 6 high-power transistors. These, combined with a massive low-noise 800VA toroidal transformer, permit this amplifier to deliver currents in excess of 25A, ensuring no loss of performance even into loads that dip below 2 ohms. The massive power delivery of this amplifier makes it ideal for driving difficult loudspeaker loads.

The topology of 505 is very much in the Meridian tradition. A high-precision, fast, DC-precise input stage is combined with fully complementary amplification and output stage. The 505 also uses Meridian’s well tried self-adjusting bias and error-correction output circuitry.
