Frequently Asked Questions - SP400 Citronic

How do I connect my speakers to the SP400?

Use bare wire or banana plugs into the speaker binding posts on the rear panel. Ensure correct polarity (+/-) and adequate wire gauge.

Can I play music from my phone?

Yes, you can use Bluetooth pairing or connect via the AUX 3.5mm input on the front panel.

What should I do if the receiver doesn't power on?

Check the power cord connection, ensure the mains outlet is live, and verify the standby button on the front panel or remote is pressed.

How do I reset to factory settings?

Press and hold the power button for 10 seconds until the display flashes. Release and the unit will reboot with default settings.

The remote control isn't working.

Replace the CR2032 battery in the remote, ensure there's a clear line of sight to the receiver's IR sensor, and check if the remote is in correct mode.

Can I connect a subwoofer?

Yes, use the Subwoofer Pre-out RCA jack to connect a powered subwoofer. Adjust the subwoofer level on the sub itself.

What is the maximum power output?

The SP400 delivers 100W RMS per channel into 4 ohms, or 70W RMS into 8 ohms (both channels driven).

How do I clean the receiver?

Disconnect from power. Use a soft microfiber cloth slightly dampened with water to wipe the exterior. Do not use chemicals or spray directly.

I hear a humming noise from the speakers.

Ensure all cable connections are secure, avoid running audio cables parallel to power cords, and try connecting devices to the same power strip.

WARNING

An equilateral triangle enclosing a lightening flash/arrowhead symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure which may be of sufficient magnitude to constitute a risk of electric shock.

An equilateral triangle enclosing an exclamation point is intended to alert the user to the presence of important operating and service instructions in the literature enclosed with this unit.

IMPORTANT SAFETY INSTRUCTIONS

When using this electronic device, basic precautions should always be taken, including the following:

1. Read all instructions before using the product.
2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming pool, etc.).
3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling.

4. This product, in combination with headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an audiologist.

5. The product should be positioned so that proper ventilation is maintained.

6. The product should be located away from heat sources such as radiators, heat vents, or other devices (including am plifiers) that produce heat.

7. The product should be connected to a power supply only of the type described in the operating instructions or as marked on the product. Replace the fuse only with one of the specified type, size, and correct rating.

8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other devices so that the outlet's or extension cord's power rating is exceeded, and (3) never be left plugged into the outlet when not being used for a long period of time.

9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure's openings.

10. The product should be serviced by qualified service personnel if:

A. The power supply cord or the plug has been damaged.
B. Objects have fallen into, or liquid has been spilled onto the product.
C. The product has been exposed to rain.
D. The product does not appear to operate normally or exhibits a marked change in performance.
E. The product has been dropped, or the enclosure damaged.

1. Do not attempt to service the product beyond what is described in the user maintenance instructions. All other servicing should be referred to qualified service personnel.

FRONT & REAR CONNECTIONS

FRONTPANEL

1. POWERSWITCH

To turn the unit ON or OFF, press the Left or Right portion of this button. Before turning on the amplifier, check all connections and turn down the level controls. A momentary muting is normal when turning the amplifier on or off.

(Caution: Always turn on your power amplifier last, after all your other connected equipment, and always turn off your power amplifier before your other connected equipment.)

2. POWERLEDINDICATORS

These LEDs illuminate when the power is turned "ON".

3. LIMITLEDINDICATORS

These LEDs illuminate if any section of the power amplifier's output are within 3dB of clipping. Occasional blinking of the LEDs are acceptable, but if they remain on more than intermittently you should turn down either the power amplifier's level controls or

reduce the output level of the preceding component to avoid audible distortion.

4.SIGNALLEDINDICATORS

These LEDs illuminate to confirm the presence of an input signal greater than 100 mV at that channel of the amplifier

5.PROTECTLEDINDICATORS

These LEDs illuminate if the power amplifier s output connection is shorted or the load impedance is too low. When either of these LEDs is lit up, turn OFF the power and check the output's connection to verify that it is correct, then turn ON the power again.

6.LEVELCONTROLS

These control the level of signal coming into each channel. The actual voltage gain of the amplifier is shown in dB. Turn these controls counterclockwise if the peak LEDs illuminate steadily (indicating too strong an input signal).

BACKPANEL

7. POWERCONNECTOR

The cord connector is used to connect the AC power source to your power amplifier.

(CAUTION:DONOTREMOVETHECENTERGROUNDING PIN.)

8.FUSES

Fuse holders. If these fuses continuously blow, shut off the unit and have it serviced by qualified service personnel.

9.ACVOLTAGESELECTORSWITCH

Before plugging in the power cord, check to see that the unit is set for the proper voltage for your a rea:\~115V(60Hz)or \~230V(50Hz).

10. INPUT CONNECTORS

Connect your input signal to these balanced 1/4"TRS input jacks.

11.L/RCHANNELOUTPUTCONNECTORS

RACK MOUNTING

The SIR series are designed for standard 19" rack mounting as well as "stack" mounting without a cabinet. Use 4 screws and washers for mounting to the front rack rails. It is also a good idea to support the amps also in the rear, especially for mobile use where the amps will be subjected to shocks.

AMPLIFIER COOLING

Also pay close attention to the cooling requirements. Never block the air vents in the back, side and front of the amplifier if the load seen by amplifier is less than 4 ohms and the amplifier is being run at high output levels. For best results, in such high output power applications you should augment the amplifier's air flow with a rack cooling system.
