Its circuit design is based heavily on Rega’s reference Aura MC phonostage, with adjustable loading and gain options that allow it to be matched to different cartridge requirements.\u003c\/p\u003e\n\u003cp\u003eThe Aos MC uses a two-stage all-analog amplifier with no digital control circuitry. Its fully aluminum half-width case helps screen the internal circuit from stray RFI, while the circuit layout avoids unnecessary components in the signal path. A self-adjusting servo control compensates for variations in ambient or operating temperature.\u003c\/p\u003e\n\u003cp\u003eThe first stage uses parallel-connected, low-noise FETs configured as a compound pair, with no bias current flowing in the cartridge coil. The MC input provides selectable resistive loading from 70 Ω to 400 Ω, capacitive loading from 1,000 pF to 4,300 pF, and a 6 dB input sensitivity adjustment via the rear panel. Automatic standby is included and can be deactivated using rear-panel DIP switches.\u003c\/p\u003e\n\u003cp\u003e The second stage is a symmetrical, class A, differential amplifier with a common base driver stage; this is also used as the active amplifier in the low-frequency part of the RIAA equalization stage.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDedicated moving coil phonostage\u003c\/li\u003e\n\u003cli\u003eFully adjustable loading\u003c\/li\u003e\n\u003cli\u003eFactory pre-set for use with all Rega MC cartridges\u003c\/li\u003e\n\u003cli\u003eCircuit design based on the Reference Aura MC\u003c\/li\u003e\n\u003cli\u003eCustom aluminum design half-width case\u003c\/li\u003e\n\u003cli\u003eAutomatic standby\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eType:\u003c\/b\u003e Moving coil phonostage\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCircuit Design:\u003c\/b\u003e Two-stage all-analog amplifier\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Load:\u003c\/b\u003e 70 Ω, 100 Ω, 150 Ω, 400 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCapacitive Load:\u003c\/b\u003e 1,000 pF, 4,300 pF\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRIAA Accuracy:\u003c\/b\u003e Better than ±0.2 dB, 65 Hz–70 kHz, 100 kΩ output load\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Sensitivity (Gain I, Gain II):\u003c\/b\u003e 69.3 dB, 63.5 dB \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Consumption:\u003c\/b\u003e 20 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eStandby Power Consumption:\u003c\/b\u003e 0.4 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (WHD):\u003c\/b\u003e 8.66\" x 3.15\" x 12.99\" (220 x 80 x 330 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 6.39 lb.
