The 3400 offers all of the advanced circuitry and control features of the 3100, plus higher power, more
sophisticated tone controls, and the convenience of remote-control operation.
The power amplifier section of the 3400 is the NAD 2400 Power Amplifier.
Conservatively rated at 100 watts per channel for continuous test tones, its Power Envelope circuit
produces 370 to 440 watts/channel of long-term tone-burst power for musical climaxes. For special
situations it can be converted to a bridged mono amp with twice the power (200 watts continuous, 800
watts dynamic) and paired with the 2400 for stereo. Current peaks of up to 40 amperes are available to
control voice-coil motion in low-impedance speakers.
Only a very few expensive separate power amplifiers can equal the solid speaker-driving power of the
3400.
In the 3400, the phono pre-amp, wide-range line-level input circuits and all operating controls are the
same as those in NAD’s finest preamplifier, the 1300.
They are virtually overload-proof, with 10 volts of headroom for peaks (14 dB more than needed to
accommodate the maximum output of any CD player), and they are also exquisitely free from hum and
noise; the signal/noise ratio of the 3400, from the CD input to the speaker terminals, is an impressive
116 dB. The most subtle details and faintest traces of hall ambience are reproduced with perfect clarity.
Bass EQ and infrasonic filtering provide solid, powerful deep bass response without boomy midbass.
Semi-parametric tone controls combine the simplicity of ordinary bass and treble controls with the
musically useful flexibility of a two-band parametric equalizer. And for total operating convenience you
can use the 3400 Amplifier with NAD’s System Remote Control.
