NAD Comprehensive Guide to Using Your S300 Stereo Amplifier
Page 7

4. AUX INPUT

Input for additional line level input signals or a CD player with no balanced output. Use a twin RCA-to-RCA lead to connect the auxiliary unit’s left and right ‘Audio Outputs’ to these inputs.

5. 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 these inputs.

6. TAPE, TAPE RECORD

Connections for analogue recording and playback to an audio tape recorder of any type. Using twin RCA-to-RCA leads, connect the left and right ‘Audio Outputs’ of the tape machine to the TAPE connectors for playback and tape monitoring. Connect the left and right ‘Audio Inputs’ of the tape machine to the TAPE REC connectors for recording.

7. 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 S300’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.

8. SPEAKERS

Speaker terminals for speakers with an impedance of 4 ohms or more. Connect the right speaker to the terminals market ‘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/2 sq.mm. or thicker) stranded wire to connect loudspeakers to your S300.

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 speakers wire.

9. GROUND CONNECTOR

The S300 is provided with a GROUND terminal on the rear panel. This terminal is connected directly to the chassis of the S300. In the event of radio hum or radio interference, this terminal can be connected to a ‘true earth’ such as a copper plated rod driven several feet into the ground.

FRONT PANEL CONTROLS

1. POWER

Pressing the POWER button turns the unit On. The blue LED above the POWER button lights up. After a pause to stabilise all circuits, the relays click on to open for the signal to the loudspeakers, and the LED goes off. Pressing the POWER button again will turn the amplifier Off.

The Power LED is dark when the amplifier is on, and lights up blue when it is in Standby mode and during the start-up procedure. In case of a short-circuit of the speaker cables, the LED flashes to indicate that the protection mode is active.

When you switch on the unit by pressing the POWER button, CD is always selected as the active input, indicated by the LED above the CD button lighting up.

Pressing the Standby button on the remote handset while the S300 is On will switch it into Standby mode and the LED above the POWER button lights up. This shows that power is being supplied to the S300, but the system is currently in the Standby mode. The next time you switch the S300 on with the Standby button, the internal memory selects the input that was active when you switched it to Standby mode. If you switch off and on with the front panel POWER button, this memory is deleted, and the unit starts in CD mode.

When in Standby mode, you may press any of the input selector

 

buttons on the front panel to “wake up” your S300 with that input

 

active.

GB

CAUTION: When in Standby mode , power is still supplied to your

S300. You should switch it off using the front panel POWER button

 

when it is not being used for long periods of time.

 

2. INPUT SELECTORS

 

These buttons select the active input to the S300 and the signal sent

 

to the loudspeakers and the Tape Rec output.

 

LED’s above each button will indicate which input is currently

 

selected.

 

CD Selects the (balanced only) CD input (or other line-level source)

 

connected to the balanced 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.

 

AUX Selects a line-level source connected to the AUX sockets, such

 

as a CD player without balanced outputs as the active input.

 

TUNER Selects the tuner (or other line-level source) connected to the

 

Tuner sockets as the active input.
