NAD 310 Manuel utilisateur

310

Integrated Amplifier

• 2 x 20 Watts continuous power into 8 ohms

• 80 watts dynamic power into 2 ohms

• 5 line inputs, including mini jack input/output

• SuSi (Super Simple) circuit topology

• Massive 20 ampere peak current capability

• Tone controls defeat switch

NAD products are particularly renowned for their value for money and the Model 310 is no exception.

Pioneering new amplifier circuit topology gives this amplifier a level of performance which belie both its

price and modest specifications.

Features and Circuitry

The SuSi (Super Simple) topology gives the amplifier a peak current capability exceeding 20 Amperes

and 85 Watts dynamic power into 2Ω, allowing it to drive even the most unreasonable loads

(loudspeakers with very low impedance) with ease. Yet, the SuSi topology uses only 50% of components

and achieves 20% higher efficiency compared to amplifiers of similar specification.

Combined with this design approach is one of eliminating all unnecessary features, such as loudness,

which benefited the 310 by reinvesting the budget with better quality components such as a Hölmgren

Toroidal™ transformer.

The return is a level of performance far beyond that which one would expect to experience at this price.

This design approach inherent in all NAD products makes the NAD 310 amplifier the ideal component

for an audiophile in a tight budget or as the centre for a second system.

Audiophiles on a budget will find the mini-jacks for both input and output on the front panel easy to

connect or disconnect other budget music sources such as portable CD player, MiniDisc recorder or

other personal audio components.
