source indicated on the marking label. If you are not sure of the type of power 

supply to your home, consult your product dealer or local power company.  

The primary method of isolating the amplifier from the mains supply is to 

disconnect the mains plug. Ensure that the mains plug remains accessible at all 

times. Unplug the AC power cord from the AC outlet if the unit will not be used 

for several months or more.

12  grounding or polarization 

- This product may be equipped with a polarized 

alternating-current line plug (a plug having one blade wider than the other). This 

plug will fit into the power outlet only one way. This is a safety feature. If you are 

unable to insert the plug fully into the outlet, try reversing the plug. If the plug 

should still fail to fit, contact your electrician to replace your obsolete outlet. Do 

not defeat the safety purpose of the polarized plug.

13 power 

- Cord Protection - Power-supply cords should be routed so that they are 

not likely to be walked on or pinched by items placed upon or against them, 

paying particular attention to cords at plugs, convenience receptacles, and the 

point where they exit from the product.

14  outdoor antenna grounding 

- If an outside antenna or cable system is 

connected to the product, be sure the antenna or cable system is grounded so 

as to provide some protection against voltage surges and built-up static charges. 

Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information 

with regard to proper grounding of the mast and supporting structure, grounding 

of the lead-in wire to an antenna discharge unit, size of grounding conductors, 

location of antenna discharge unit, connection to grounding electrodes, and 

requirements for the grounding electrode.

note to catv SYStem inStaller

This reminder is provided to call the CATV system installer’s attention to Section 820-40 of 

the NEC which provides guidelines for proper grounding and, in particular, specifies that 

the cable ground shall be connected to the grounding system of the building, as close to 

the point of cable entry as practical.

15 lightning 

- For added protection for this product during a lightning storm, or 

when it is left unattended and unused for long periods of time, unplug it from the 

wall outlet and disconnect the antenna or cable system. This will prevent damage 

to the product due to lightning and power-line surges.

16  power lines 

- An outside antenna system should not be located in the vicinity 

of overhead power lines or other electric light or power circuits, or where it can 

fall into such power lines or circuits. When installing an outside antenna system, 

extreme care should be taken to keep from touching such power lines or circuits 

as contact with them might be fatal.

- Do not overload wall outlets, extension cords, or integral 

convenience receptacles as this can result in a risk of fire or electric shock.

18  object and liquid entry 

- Never push objects of any kind into this product 

through openings as they may touch dangerous voltage points or short-out parts 

that could result in a fire or electric shock.  Never spill liquid of any kind on the 

product.

INTRODUCTION

getting Started

QUICK START

In case you simply cannot wait to experience the performance of your new 

NAD T 977 Seven Channel Power Amplifier, the following QUICK START 

guide is recommended to help you get started.

Ensure that the T 977 is unplugged before making any connections. It is 

also advisable to power-down or unplug all associated components while 

making or breaking any signal or AC power connections.

1 

Set the following initial conditions: 

· 

Preamplifier’s volume level set to minimum

· 

Each channel INPUT level controls of T 977 set to minimum (MIN)

2 

Connect your speakers to the SPEAKER terminals of T 977.  Note 

suggested speaker connections as reflected in the rear panel channel 

allocations.   

3 

Connect your Preamplifier’s PRE OUT to the T 977 rear panel’s INPUT 

port. 

4 

Plug-in to a mains power source the T 977’s supplied mains power cord. 

Before connecting the plug to the mains powers source, connect firmly 

first the other end to T 977’s AC Mains input socket. The T 977 goes to 

standby mode as shown by the amber status condition of the Standby 

LED. 

5 

Plug-in also to a mains power source the Preamplifier’s mains power 

cord.  Power up your Preamplifier ahead of the T 977. 

6 

Press STANDBY button to switch ON the T 977 from standby mode. The 

Standby LED indicator will turn from amber to blue.  When the T 977 is 

switched ON from standby mode, the Channel Status LEDs will initially 

turn red and then eventually turn blue. The T 977 is ready for operation.

7 

Adjust the corresponding T 977 INPUT LEVEL CONTROL and/or 

Preamplifier’s volume control according to desired listening levels. 

SAVE THE PACKAGING

Please save the box and all of the packaging in which your T 977 arrived. 

Should you move or otherwise need to transport your T 977, this is by far 

the safest container in which to do so. We’ve seen too many otherwise 

perfect components damaged in transit for lack of a proper shipping 

carton, so please: Save that box!

NOTES ON INSTALLATION

Your NAD T 977 should be placed on a firm, level surface. Avoid placing the 

unit in direct sunlight or near sources of heat and damp. Allow adequate 

ventilation. Do not place the unit on a soft surface like a carpet.  Avoid 

placing the T 977 inside a closed cabinet that is not well ventilated as this 

may compromise the T 977’s performance and reliability.  

Ensure that the T 977 is unplugged before making any connections.  For 

best performance, use quality speaker leads of 16 gauge (1.5mm) thickness 

or more.  If the unit is not going to be used for some time, disconnect the 

plug from the mains power source.

Should water get into your T 977, immediately press the Standby button 

and then disconnect the mains power cord from the mains power source. 

Have the unit inspected by a qualified service technician before attempting 

to use it again.

do not remove the cover; there are no uSer-Serviceable 

partS inSide.

Use a dry cloth for cleaning.

BARE WIRES AND PIN CONNECTORS

warning:

 The terminals marked with this symbol 

are hazardous live.  External wiring connected to these 

terminals requires installation by an instructed person or 

the use of ready-made leads or cords.

Bare wires and pin sockets should be inserted into the hole in the shaft 

of the terminal. Unscrew the speaker terminal’s plastic bushing until the 

hole in the screw shaft is revealed. Insert the pin or bare cable end into 

the hole and secure the cable by tightening down the terminal’s bushing. 

Ensure bare wire from the speaker cables does not touch the back panel or 

another socket. Ensure that there is only 1/2” (1cm) of bare cable or pin and 

no loose strands of speakers wire.
