NVA A70 Monoblock Amplifiers

The NVA A70 Mk2 is a monoblock hi-fi amplifier designed purely for the best and most satisfying musical reproduction. It will deal with the most difficult loads due to the size of the heat-sink used as an integral part of the case design.

The difference compared with the Mk1 A70s is this heat-sinking capability which meant a case redesign.

NVA A70 Specifications:

Inputs - One line level per channel (extra inputs mod available)

Outputs - 4mm speaker sockets per channel

Power Output - 70w

Power Supply - 1 x 160va each

Dimensions - w240mm x h160mm x d240mm

The A70 is a 70w monoblock power amplifier designed to be used with a passive pre-amp like the NVA P50 or P90 but will work ok with active pre-amps or direct feed from a DAC or computer audio system with volume control. It should only be used with low capacitance speaker cable like NVA LS series speaker cable and NVA Super Sound Pipe, Sound Pipe or Sound Cord interconnects due to the unfiltered nature of the design. Litz, Goertz or Cat5 cable or other designs of high capacitance cable will damage the amplifier.

Warranty is for two years parts and labour and after that a further three years it will be repaired on a no profit / cost basis.

Available in 120v or 240v please stipulate on purchase.

NVA AMPLIFIERS AND SPEAKER CABLES – WARRANTY

Only NVA LS1, LS2, LS3, LS5, LS6 and LS7 is recommended for use with this amplifier, other cables will invalidate the warranty.

For best sound the amplifier should be left powered up. Electricity consumption is very low. It is for this reason that the power switch is located on the back panel, where it may not be easy to reach. Turn the amplifier off when you do not intend to listen to it for extended periods.

NVA amplifiers are unique, and one thing that makes them so is the minimal compensation for the output stage. It is very possible to send this amplifier into oscillation by connecting too large a capacitive load on the output, the usual culprit being unsuitable speaker cable such as Litz or Goertz type constructions.

If you insist on using other cable (this will invalidate warranty) please ensure it is no more than 200pf per metre and it should not be used in lengths over 10 metres. If you wish to Bi-Wire this can only be done with NVA cable and they can be made that way on order for a small added cost.

For design performance only NVA Sound Pipe, Super Sound Pipe or Sound Cord Interconnects should be used, but this is for sonic as opposed to safety reasons.
