Our T 977 is an extremely powerful, high performance seven-channel power amplifi er capable of delivering the musical muscle that serious movie
lovers demand. Along with NAD’s T 187 Surround Sound Preamp Processor, you’ll enjoy a sophisticated home theatre system that will rival gear
costing many times more. We doubt you’ll fi nd anything that comes close to the T 977’s overall musical satisfaction, well-rounded performance, and
complete value.
> Powerful Impact
The T 977 unleashes 140 watts of continuous power and
fl exes its musical muscle with peaks of 1000 watts into seven
channels for an audio experience that simply has to be heard.
Thanks to its specially designed Holmgren Torodial power
supply, the T 977 will never come up short in power, handling
even the most demanding music and fi lm soundtracks with
ease and control.
> Legendary Technology
Our NAD PowerDrive circuit delivers very high dynamic power
and low impedance drive to accurately control loudspeakers,
resulting in remarkably musical and relaxed sound. PowerDrive
gives the T 977 maximum power no matter what you throw at it.
We also include our exclusive Soft Clipping feature to protect
your speakers (and ears) from damaging clipping distortion.
> ‘Music First’
With total elimination of audible distortion at any listening
level, the T 977 provides precise imaging and spine tingling
realism in movies and music alike. Each of its seven channels
is fully independent to eliminate inter-channel interference and
noise with the use of NAD’s active ground circuit, and features
MOSFET Class A input and driver stage circuits with a high-
current output stage design employing high speed, discrete
output devices. The result is superb dynamic quality and
musical detail.
> Radically Cool
The T 977 is cooled and controlled by a uniquely designed
forced air system originally introduced in our top-of-the-
line Masters Series M25. The circuit measures not only the
temperature of the heat sinks, but also the level of the input
signals, to automatically silence the fans so as not to spoil quiet
music passages. A combination of fuse and electronic non-
intrusive protection safeguards each of the seven channels
against excess temperature, DC fault, and loudspeaker
short-circuit.
> Installer’s Dream
Developed with system integration and fl exibility in mind, the
T 977 includes a programmable 12V trigger input. Individual
gain adjustment for each channel promotes easy, accurate
system confi guration, as does the integral 12V trigger turn-on
response. The T 977 is also outfi tted with heavy-duty, fi ve-way
connectors and gold-plated RCA input jacks.
> Effi cient and Reliable
The T 977 power supply is designed with our exclusive
Holmgren transformer, which together with PowerDrive, acts as
a “fuel cell” that supplies power to the audio circuitry and power
amp, yet maintains superb isolation between the amplifi er and
any “dirty” noise on the AC supply that could affect the overall
audio performance. A convenient automatic standby mode
saves energy when the T 977 is idle.
