S300 user manual

Have the unit inspected by a qualified service technician before attempting to use it again. Switch the unit off before making any connections.

The RCA connectors on your S are colour coded for convenience. Always 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 or 2 sq. If the unit is not going to be used for some time, disconnect the plug from the AC socket. Do not open the amplifier or attempt to modify or repair it yourself. Refer all servicing to a qualified technician.

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. The S comes supplied with a separate AC Mains cable. Always disconnect the AC Mains cable plug from the live wall socket first before disconnecting the cable from the S Mains input socket.

A notice printed on the rear indicates the AC power-line voltage that the preamplifier requires. If you wish to transport your S to a nation that employs a different power-line voltage, an authorised NAD dealer or service agency can convert it for such use.

The wiring standard used for the balanced connectors is: Pin 1:Chassis Earth Ground. The resulting distortion and noise may depend on the orientation of AC power plugs in their sockets.

Designers of some audiophile cables combat this contamination by leaving the shield unconnected at one end. Since the shield is grounded at only one end, the performance of such a cable may depend on the direction of its connection, i. A three-wire balanced connection avoids all of these uncertainties.

The separate cable shield, connected to the amplifier chassis at both ends, protects the audio signal from all forms of interference and power-supply noise. Input for additional line level input signals or a CD player with no balanced output.

Input for a Tuner or other line-level signal source. Connections for analogue recording and playback to an audio tape recorder of any type. This allows centralised control of a complete system or gives system control from more than one room. Speaker terminals for speakers with an impedance of 4 ohms or more. 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.

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 should be inserted into the hole in the shaft of the terminal. Avoid any danger of bare metal from the speaker cables touching the back panel or another connector. This terminal is connected directly to the chassis of the S After a pause to stabilise all circuits, the relays click on to open for the signal to the loudspeakers, and the LED goes 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. This shows that power is being supplied to the S, but the system is currently in the Standby mode. The next time you switch the S on with the Standby button, the internal memory selects the input that was active when you switched it to Standby mode.

CD Selects the balanced only CD input or other line-level source. Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the Tape sockets. To show which input is active when in tape monitor mode, its indicator light will stay lit. Press MUTE button again to restore sound. Press it to select, press it again to revert to normal input selection. The motorised Volume Control on the front panel will indicate the level set. The S is designed with no balance control.

As most serious listening takes place in the optimum position between the speakers, we have decided to leave out this potentially detrimental control. Some semiconductor devices are easily damaged by static electricity.
