The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

NOTES ON INSTALLATION.

Your NAD 317 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. Do not place it in an enclosed position such a bookcase or cabinet that may impede the air-flow through the ventilation slots.

Switch the unit off before making any connections. The RCA connectors on your NAD 317 are colour coded for convenience. Red and white are Right and Left audio respectively, and yellow for NAD-Link.

The NAD 317 comes with RCA leads for basic connections. Where additional leads are required, use high quality leads and connectors for optimum performance and reliability. Ensure that leads and connectors are not damaged in any way and all connectors are firmly pushed home.

For best performance, use quality speaker leads of 16 gauge thickness or more.

If the unit is not going to be used for some time, disconnect the plug from the AC socket.

Should water get into your NAD 317, shut off the power to the unit and remove the plug from the AC socket. 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 soft cloth to clean the unit. If necessary, lightly dampened the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

REAR PANEL CONNECTIONS.

1. CD INPUT

Input for a CD or other line-level signal source. Use a twin RCA-to-RCA lead to connect the CD player left and right 'Audio Outputs' to this input. The NAD 317 only accepts analogue signals from your CD player.

2. VIDEO INPUT

Input for the audio signal from a stereo VCR (or stereo TV/Satellite/Cable receiver) or other line-level audio source. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Out' of the unit to these inputs. Note: These are audio inputs only.

3. TUNER INPUT

Input for a Tuner or other line-level signal source. Use a twin RCA-to-RCA lead to connect the Tuner left and right 'Audio Outputs' to this input.

4. AUX INPUT

Input for additional line level input signals such as another CD player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio Outputs' to this input.

5. TAPE 1 IN, OUT

Connections for analogue recording and playback to an audio tape recorder of any type. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Output' of the tape machine to the TAPE 1 IN connectors for playback and tape monitoring. Connect the left and right 'Audio Input' of the tape machine to the TAPE 1 OUT connectors for recording.

6. TAPE 2 IN, OUT

Connections for analogue recording and playback to a secondary audio tape recorder of any type. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Output' of the tape machine to the TAPE 2 IN connectors for playback and tape monitoring. Connect the left and right 'Audio Input' of the tape machine to the TAPE 2 OUT connectors for recording.

7. PRE OUT, MAIN IN

Connections to an external pre-amplifier, power amplifier or processor, such as a surround-sound decoder. In normal use these should be connected together using the links supplied. To connect your NAD 317 to external processor or amplifier sections first remove these links. Use a twin RCA-to-RCA lead to connect to the left and right 'Audio Input' of the Power amp or processor to the Pre Out connectors.

Connect the left and right 'Audio Output' of the Pre-amp or processor to the Main In connectors.

Note: The Pre-Out output signal will be affected by the NAD 317's volume and tone control settings.

8. NAD-LINK IN, OUT

The NAD-Link connector is used to pass commands from the remote control handset to and from other units fitted with NAD-Link connectors. This allows centralised control of a complete system or gives system control from more than one room. To function with other units, connect the NAD 317's NAD-Link OUT to the NAD-Link IN on the other unit. NAD-Link connectors can be daisy-chained, IN to OUT, so that a whole system can be controlled from the remote control facilities of one unit.

A single NAD-Link connection from a hi-fi system in a second room will allow remote control of Multi Room systems.

9. SPEAKERS

Speaker terminals for speakers with an impedance of 4 ohms or more.

Connect the right speaker to the terminals marked 'R +' and 'R-' ensuring that the 'R+' is connected to the '+' terminal on your loudspeaker and the 'R-' is

connected to the loudspeaker's ‘-’ terminal.

Connect the terminals marked 'L+' and 'L-' to the left speaker in the same way.

Always use heavy duty (16 gauge or thicker) stranded wire to connect loudspeakers to your NAD 317.

The high-current binding post terminals can be used as a screw terminal for cables terminating in spade or pin connectors or for cables with bare wire ends.

SPADE CONNECTORS

These should be slotted under the terminal's screw bushing, which is then fully tightened. Ensure the connector is tightly secured and there is no danger of bare metal from spade connectors touching the back panel or another connector, as this may cause damage.

BARE WIRES AND PIN CONNECTORS

Bare wires and pin connectors 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.

Avoid any danger of bare metal from the speaker cables touching the back panel or another connector. Ensure that there is only 1/2" (1cm) of bare cable or pin and no loose strands of speaker wire.

10. SOFT CLIPPING

When an amplifier is driven beyond its specified power output, a hard distorted sound can be heard on very loud sounds. This is caused by the amplifier cutting off or 'hard clipping' the peaks of sound that it was not designed to reproduce. The NAD Soft Clipping circuit gently limits the output of the system to minimize audible distortion if the amplifier is overdriven.

If your listening involves moderate power levels you may leave the Soft Clipping switch to Off. If you are likely to play at high levels, that could stretch the amplifier's power capability, then switch Soft Clipping On.

The Soft Clipping LED on the front panel will illuminate when the amplifier is in Soft Clipping mode.

11. BRIDGE SWITCH

The NAD 317 can be used as part of a higher power stereo or home-theatre system, by connecting additional power amplifiers. If the power amp section in the NAD 317 is to be used to drive a single speaker, then use the Bridge switch to run the left and right power amplifiers as a single channel, high power unit. Set the Bridge switch to the 'Bridge' position and connect the speaker to the terminals marked 'L+' and 'R+' ensuring that the 'L+' is connected to the '+' terminal on your loudspeaker and the 'R+' is connected to the loudspeaker's '-' terminal. In Bridged mode left channel is taken as the input and the NAD 317 will produce approximately 240W into an 8 ohm loudspeaker. In this mode, the amplifier sections will react as though the speaker impedance has been halved. So speakers with very low impedances (under 4 ) are not recommended as they may cause the amplifier's thermal cut-out to operate if played at high levels.

The Bridge LED on the front panel will illuminate when the amplifier is in Bridge mode.

12. AC LINE CORD.

After you complete all connections to the preamplifier, plug the AC line cord into a "live" AC socket.

13. AC CONVENIENCE OUTLETS (U.S. CANADIAN MODELS ONLY

The AC power cords of other units in the audio system can be connected directly to the AV 711's unswitched AC outlets. If another stereo component is plugged into the UNSWITCHED AC outlet, power will be supplied whether your AV711 is on or off.

FRONT PANEL CONTROLS.

POWER, SPEAKERS AND HEADPHONE FUNCTIONS.

1. POWER

Pressing the POWER switch turns the unit On and after a short pause, the Power indicator LED will illuminate green. Pressing the POWER switch again will turn the amplifier Off.

When the NAD 317 is switched On, pressing the Standby button on the remote handset will put the NAD 317 into Standby mode and the Power indicator will turn amber. The amber Power indicator shows that power is being supplied to the NAD 317, but the system is currently in the Standby Mode.

CAUTION: When in Standby, power is still supplied to your NAD 317. You should switch it off using the front panel Power switch when it is not being used for long periods of time.

2. HEADPHONE SOCKET

A 1/4" stereo jack socket is supplied for headphone listening and will work with conventional headphones of any impedance. Inserting a headphone jack into this socket automatically switches off the loudspeakers. The volume and tone and balance controls are operative for headphone listening. Use a suitable adapter to connect headphones with other types of connectors, such as 3.5mm stereo 'personal stereo' jack plugs.

Warning: Make certain that the volume control is turned to minimum (fully anti-clockwise) before connecting headphones.

Listening at high levels can damage your hearing.

TONE FUNCTIONS

3. BASS & TREBLE CONTROLS

The NAD 317 is fitted with BASS and TREBLE tone controls to adjust the tonal balance of your system.

The 12 o'clock position is 'flat' with no boost or cut

and a detent indicates this position. Rotate the control clockwise to increase the amount of Bass or Treble. Rotate the control anti-clockwise to decrease the amount of Bass or Treble. The Tone controls do not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

4. TONE DEFEAT

The TONE DEFEAT switch bypasses the tone control section of the NAD 317. If the Tone Controls are not normally used and left in the 12 o'clock position, then it is advisable to switch out the Tone Control section altogether by using this switch. In the 'out' position, the Tone Control circuits are active, pushing the TONE DEFEAT switch in bypasses the Tone Control section.

INPUT SELECTORS.

5. INPUT SELECTORS

These buttons select the active input to the NAD 317 and the signal sent to the loudspeakers, the Tape outputs and the PRE OUT sockets.

LEDs inside each button will indicate which input is currently selected.

TUNER: Selects the tuner (or other line-level source) connected to the Tuner sockets as the active input.

AUX: Selects a line-level source connected to the AUX sockets as the active input.

CD: Selects the CD (or other line-level source) connected to the CD sockets as the active input.

VIDEO: Selects the VCR (or stereo TV/Satellite/Cable receiver) connected to the VCR sockets as the active input.

TAPE FUNCTIONS.

6. TAPE 1 MONITOR/TAPE 2

Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the Tape 1 sockets. Press the Tape 1 button once to select it and again to return to the normal input selection.

Tape 1 is a tape Monitor function which does not override the current input selection. For example, if the CD is the active input when TAPE 1 is selected, then the CD signal will continue to be selected and sent to both the TAPE 1, and TAPE 2 OUTPUT sockets, but it is the sound from the recorder connected to Tape 1 that will be heard on the loudspeakers.

To show which input is active when in Tape Monitor mode, its indicator light will stay lit.

TAPE 2: Selects Tape 2 as the active input.

TO MAKE A RECORDING

When any source is selected, its signal is also fed directly to any tape machine connected to the TAPE 1 or TAPE 2 OUTPUTS for recording.

TAPE TO TAPE COPYING

You can copy between two tape machines connected to your NAD 317. Put the source tape in the machine connected to Tape 2 and the blank tape into the recorder connected to Tape 1. By selecting TAPE 2 input you can now record from Tape 2 to Tape 1 and monitor the signal coming from the original tape.

Also you can use Tape 1 as the source and copy to Tape 2 but Tape 2 input has to be selected for the duration of the recording. By selecting Tape 1 Monitor input, you can now monitor the signal coming from the original tape.

CAUTION: WHEN TAPE 2 IS SELECTED, ONLY ONE TAPE MACHINE SHOULD BE SET IN RECORD MODE. IF BOTH ARE SET IN RECORD MODE, WITH TAPE 2 SELECTED, A FEEDBACK LOOP RESULTS WHICH MAY CAUSE A LOUD "WHISTLE OR HOWL", POTENTIALLY DAMAGING YOUR AMPLIFIER OR LOUDSPEAKERS.

BALANCE AND VOLUME.

7. BALANCE

The BALANCE control adjusts the relative levels of the left and right speakers. The 12 o'clock position provides equal level to the left and right channels. A detent indicates this position.

Rotating the control clockwise moves the balance towards the right. Rotating the control anti-clockwise moves the balance to the left. The BALANCE control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

8. VOLUME

The VOLUME control adjusts the overall loudness of the signals being fed to the loudspeakers. It is motor driven and can be adjusted from the remote control handset. The VOLUME control does not affect recordings made using the Tape outputs but will affect the signal going to the Pre-amp output (Pre Out).

INDICATORS AND REMOTE SENSOR

9. PROTECTION

In Protection mode; the loudspeakers have been disconnected by an internal relay. This mode is activated briefly during turn-on and turn-off, to protect the speakers from low-frequency thumps. At other times the Protection mode may be activated by severe overheating, short-circuited speaker wiring, or an internal fault.

If the Status light continues to glow red, switch the Power OFF, allow to cool and then switch Power ON. If the protection system interrupts the sound even when the amplifier is cool, return the amplifier to your NAD dealer for service. The protection relays may be disengaging to protect your speakers from a circuit fault, such as an improper DC voltage at the speaker terminals.

10. SOFT CLIPPING

Shows that the NAD 317 is in Soft Clipping mode.

11. BRIDGE

Shows that the NAD 317 is in bridged mode.

12. SENSOR
