SOUND TOWN NIX-D4800 Professional 4-Channel Power Amplifier

IMPORTANT SAFETY INSTRUCTIONS

1. Read all safety and operating instructions before using this product.

2. All safety and operating instructions should be kept for future reference.

3. Read and understand all warnings listed on the operating instructions.

4. Follow all operating instructions to operate this product.

5. This product should not be used near water, i.e. Bathtub, sink, swimming pool, web basement etc.

6. Only use a dry cloth to clean this product.

7. Do not block any ventilation openings, it should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air.

8. Do not install this product near any heat sources, such as, radiators, heat registers, stove or other apparatus (including heat producing amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The side blade or the third prong are provided for your safety if the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord being walked on or pinched particularly at Plugs, convenience receptacles and the point where they exit from the apparatus. Do not break the ground pin of the power supply cord.

11. Only use attachments specified by the manufacturer.

12. Use only the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus.
    When a cart is used use caution when moving cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Care should be taken so that objects do not fall and liquids are not spilled into the unit through the ventilation ports or any other openings.

15. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way; such as, power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally or has been dropped.

16. WARNING : To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

17. When the MAINS plug, or an appliance coupler is used as the disconnect device, the disconnect device should remain readily operable.

18. Protective Ground Terminal: The apparatus shall be connected to an AC main socket with a protective earth ground connection.

CAUTION
RISK OF ELECTRIC SHOCK.DO NOT OPEN

1. Power Switch
   This heavy-duty, rocker-type switch turns on the mains power to the amplifier. When the mains power is applied, there is a three second delay in activation of the unit. This reduces / eliminates the turn on transients associated with the system equipment connected to the amplifier and protects loudspeakers.

2. Volume Control
   These controls are used to adjust the input gain of each channel. They determine how loud each channel of the power amplifier will sound for a given input signal level. Maximum input gain is achieved at the fully clockwise setting, and this setting yields maximum mixer/ system headroom. A setting of less than fully clockwise will yield lower system noise at the expense of mixer/ system headroom. Turning the control fully counterclockwise is the off setting. It is always a good idea to power up any new installation at this setting to protect the loudspeakers.

3. Power LED
   These indicators illuminate when the AC mains power is being supplied to the amplifier and all channels are operational. If any channel experiences fault conditions, exceeds safe operating temperature limits, or if the mains circuit breaker trips, the power LED will be dark.

4. Signal (Level) LED
   These indicators illuminate when the associated channel has signal input.

5. Overload LED (Clip)
   These indicators illuminate when the associated channel has been overloaded. An occasional flickering is acceptable. If LED is lit continuously adjust the level control and reduce the output level of connected sources. Failure to do so may lead to premature failure of your speaker.

6. LINK (MODE SWITCH: STEREO/PARALLEL)

   • A: STEREO MODE: Switch the ‘LINK’ to OFP position will allow stereo input from two separate feeds to INPUT 1&2, the OUTPUT1&2 speakon will power out separately.
   • B: PARALLEL MODE: Switch the “LINK’ to ‘ON” position and input one mono signal from either INPUT1 or INPUT2,
     the other INPUT socket is invalid at this mode. OUTPUT1&2 speakon will power out separately for the same signal.

• NOTE : DO NOT input from both INPUT1&2 at the same time when in PARALLEL mode. The other XLR socket without signal input can be used as a signal link out at this mode. (A male to male XLR cable will be needed.) CH3&4 operate the same as CH1&2 with STEREO and PARALLEL options. 7. SENSITIVITY (0.77V/1.0V/1.44V)
  This switch allows to adjustment the input sensitivity. Default setting is 0.775V (OdB), when the signal source from your audio device are of low gain level, please switch the sensitivity to be 1.OV or 1.4V to raise the input gain level.

  8. INPUT
     XLR 3 (female) connectors are provided for signal inputs (Balanced input).

  9. SPEAKON OUTPUT
     Use these NL4 sockets in order to connect the outputs to the loudspeakers.

  10. MAIN SOCKET INPUT
      Use the incorporated cable to connect the device to an adequate main supply point. It’s important to supply the proper AC line voltage (100V-130V) to the unit. Do not connect to intermittent or faulty power.
