5010 PRE/POWER AMPLIFIERS FROM EXPOSURE

Exposure’s top-of-range 5010 series features a preamplifier and a pair of mono power amplifiers

The new 5010 series features two products: a preamplifier and a pair of mono power amplifiers.

Smaller than their MCX predecessors, the power amplifier offers nothing but a power button on the front fascia, while the preamp includes a power switch, a single input selector knob and the volume control.

The mono power amplifier features an 800W transformer with dual rectification and two 10000uF screw terminal capacitors, along with eight power transistors per channel. A slow start circuit reduces the power-on surge.

Cascode circuits are used for the input and second amplifier stages and are fed from active rail smoothing circuits. Welwyn RC55 resistors and polypropylene and polystyrene capacitors are used too. The input is relay-switched between balanced or single-ended.

One of the inputs can be reconfigured as either an MM or MC phono option with the addition of an extra PCB or as a DAC option with the addition of a plug-in board. The latter is capable of up to 24bit/192kHz PCM and DSD 64 and comes with two inputs: USB and BNC, with auto-switching between them.

The preamplifier has a balanced output and is DC coupled using servos at the output and only one capacitor at the input. Its power supply features a 200W transformer, fast rectifiers and 24 high-quality smoothing capacitors.
