This manual contains important instructions for the safe operation of the unit. Read and follow the safety instructions and all other instructions. Keep the manual for future reference. Make sure that it is available to all those using the device. If you sell the unit, please make sure that the buyer also receives this manual.
You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment. Properly shielded and grounded cables and connectors must be used for connection to host computers and/or peripherals in order to meet FCC emission limits. To reduce the risk of electric shock, the speaker cable should be connected to the apparatus and the speakers in accordance with the following instructions.
DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using unsafe adapters. A polarized plug has two blades - one wider than the other. A grounding plug has a third ground prong in addition to the two main conductors. The wide blade or third grounding prong is provided for your safety. If the provided plug does not fit your outlet, consult an electrician to replace your obsolete outlet. If you replace the power cord, only use one of similar type and equal or greater current rating.
For Class II apparatus only: This symbol means that the equipment is a Class II or double insulated electrical appliance. It has been designed in such a way that it does not require a safety connection to electrical earth. When servicing use only identical replacement parts installed by an instructed person or with use of ready-made leads or cords.
WARNING SYMBOLS
TYPE OF DANGER: - Danger Zone | |
TYPE OF DANGER: - High Voltage | |
Hazardous Voltage Hazardous voltage may be present at cable ends and screw terminals. The connection of screw terminals as well as all maintenance and repair work on the electrical installation of the device must only be performed by qualified electrical personnel in volt-free-condition. Failure to do so may result in electric shock and risk of fire and loss of life. By all means you have to observe all electrical safety instructions applicable at the place of operation. | |
Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord) with a protective contact plug. Do not modify the mains cable or plug. Failure to do so could result in electric shock/death or fire. If in doubt, seek advice from a registered electrician. |
This product has been tested by ETL and has been found to be complying with:
The mains plug/appliance coupler is used as disconnect device, the disconnect device shall remain readily operable.
To avoid damage to the XA amp or connected devices, please turn off and unplug the XA amp before making any changes to the wiring.
Failure to do so can potentially result in severe damage to your amplifier & loudspeakers
Use Class 2 wiring for speaker connections.
Wiring the speaker connector with bare wire:
While the amplifier does self-protect under most improper output conditions, misconfiguration of loudspeaker mode and incorrect connection of loudspeakers could damage connected loudspeakers and/or amplifier.
Please refer installation to a qualified installation professional, and always check state and local electrical codes when installing.
There are 3 options for controlling the power ON/OFF
Ensure that the amp is plugged into a 15 Amp power socket. At full power the amp will require in excess of 10 Amps. Ensure the amp has air clearance with nothing covering the ventilation slots. 6 inches of clearance is recommended, or, if rack mounted, please use a cooling fan.
Double-check all connections from connected processors or AVR 's, and connections to speakers. Make sure all connections are good and that there are no stray wires, or strands of wire.
Tip - If speaker wires are running through walls or ceiling, you can check that the speaker wires are connected correctly by taking a 9V battery and momentarily touching the speaker wire to the + and – terminals. If the speakers are connected there will be a small 'popping' sound. Turn the volume level of the connected Processor or AVR down to zero for all channels.
Power-On - Normal Operation
Press the front panel switch labeled POWER. After a short pause the front panel LED indicators will light-up.
Front Panel Status LEDs
Power: Bright Blue
Standby: Yellow
Protection: Red
Power:
Blue Lights – The amp is on and working correctly
Standby:
Yellow/Orange light – The amp is in standby mode, no signal to speakers, no sound.
Protection:
Red Light – The amp has automatically detected a problem and is in protection mode to prevent damage to speakers. Turn amp off, unplug and check speaker connections for short circuits (positive and negative wires touching).
Power-on - auto signal detecting mode
Press the front panel switch labeled POWER. After a short pause the front panel LED indicators will light-up.|
When the SIGNAL position is selected the front panel indicator lights will be Yellow/Orange if there is no signal from the connected Processor or AVR. When a signal from any channel is present the indicator lights for that channel will turn to Blue and the speaker will play that signal.
Power-on – Trigger
Press the front panel switch labeled POWER. After a short pause the front panel LED indicators will light-up.
When the rear panel switch is set to TRIGGER the front panel indicator lights will be Yellow/Orange and the amp will be in Standby mode. When a TRIGGER signal is present the amp will turn on and the indicator lights will be Blue. The amp will stay on as long as there is a TRIGGER signal present. When the TRIGGER signal is removed, the amp will return to Standby and the front panel indicator lights will go to Yellow/Orange.
To turn Off
Press the front panel switch labeled POWER, all lights will turn off.
If the amp requires cleaning, wipe with a clean, dampened soft cloth. Do not use chemicals and remove any moisture. Do not use abrasive cleaners, as they may damage the paint. Do not expose the amp to insecticide, waxes, polishing agents, or an aerosol spray as moisture may enter the amp.
Should you encounter any problems with your XA amplifier please reset the power by switching off and un-plugging the amp. Re-check all connections from Processors or AVR's and to the speakers. Turn on the amp again and refer to the 'Amplifier Operation and Maintenance' instructions. If a problem still exists, contact OSD Nero's customer service department at OSDAUDIO.COM.
