Based upon the highly praised NAD106, the model 114 is the latest in the range of NAD high quality /
low price pre-amplifiers.

Following in NAD’s usual design brief of “sound quality first” the 114 utilises reliable, uncomplicated
circuit topology which allows for investment in high specification, close tolerance components such as a
large, low noise transformer, metal film resistors, polypropylene capacitors and a precision volume
control.

A carefully re-designed PCB layout contributes further to a noise and distortion free performance. The
input selectors are operated by push rods and are located as closely as possible to the input sockets to
minimise cross talk. Also featuring Gold plated RCA jacks (to give reliable signal transfer), and two tape
loops to offer flexibility for tape dubbing in either direction (or the inclusion of a signal processor). Any
input may be monitored whilst recording. A gold plated 1/4” jack socket permits most non-electrostatic
headphones to be connected to the dedicated headphone amplifier.

Still in demand by music lovers (but often disregarded by other manufacturers) is a good quality phono
stage. The phono stage in the 114 is a fine example of what can be achieved at a reasonable price. The
phono stage is switchable to allow moving coil or moving magnet cartridges to be used. Metal film
resistors, polypropylene capacitors and seven discrete transistors provide extremely low noise
performance, precise equalisation and a dynamic range of 105dB.

The tone controls operate simple low noise circuits which offer useful frequency response adjustment
without sonic compromise. A tone defeat switch provides a direct signal path to the output.
The low output inpedance allows the 114 to drive several power amplifiers in parallel and/or the use of
long interconnecting cables (without the degredation of the performance that can so often become
apparent when long cables are used).
