Installing Rack Mount Ears
If you are planning on installing this amplifier into a rack continue reading how to install the supplied rack ears.

1. Use the supplied three screws to attach the supplied rack ears to the SAM500 amp. If required, the feet on the bottom of the amplifier can also be removed at this time by unscrewing the mounting screws located in the center of each foot.
2. Due to the weight of the amplifier, it is recommended that rear supports be secured to the rear rack rails. Hardware to do this is not supplied with the amplifier and is specific to the type and depth of rack being used.

NOTE: Leave adequate ventilation above and below the amplifier when rack mounted. If there is not enough ventilation, amp may over heat and switch to standby mode.

SAM500 Amplifier Controls and Setup

Front Panel

1. Power Switch: Turns the amplifier on or off. Amplifier must be on for the trigger or auto sense modes to operate.

Back Panel

1. Line Input: For receiving line-level signals. Accepts
   either a stereo or LFE signal.

2. XLR Balanced Input: For receiving balanced signals.
   Accepts either a stereo or LFE signal

3. 12V Trigger Input: For triggering the power on/off from other devides such as processors or receivers that have a 12V trigger output. 6V minimum required for triggering.
   NOTE: Once in trigger mode, the amplifier cannot be turned on without a 12V trigger signal. To disable the 12V trigger, press and hold the navigation control knob. The power switch must be in the ON position. The trigger mode will be turned off and the amplifier will power on.

4. Service: For uploading new firmware or updates and for accessing PC App.

5. IR Input: Link to Infared (IR) hub.

6. 5-way Binding Posts: Connect your subwoofer here. Minimum impedance of the load is 4 ohms. Multiple subwoofers can be connected if the combined load impedance is 4 ohms or greater.

7. Voltage Selector Switch: The amplifier can be used on 110-120V (60Hz) or 220-240V (50H2) line voltage. To change the operating line voltage, turn the power off using the power button and unplug the power cord. Remove the plastic cover screws and the plastic cover over the voltage selector ocated on the rear of the amp. Set the switch to the correct position for the line voltage in your country. Replace the plastic cOver and screws over the voltage selector switch.
   NOTE: If required, remove the IEC line cord and replace with an IEC AC cable that matches the AC wall socket, this should be a 1OA rated cable. When the voltage selector switch is changed, the fuse must also be changed to continue to provide protection to the amplifier.

8. Power Cord Receptacle: The supplied power cord needs to be connected to this receptacle in order for the amplifier to work properly.

9. Fuse Holder: This is the power fuse access.
   WARNING! In the event the fuse must be replaced, the replacement fuse must match exactly the original fuse value or damage to the amplifier may result. Use a 8A 120V or 4A 240V fuse.
   CAUTION! Before replacing the fuse, disconnect the power cord from the power receptacle.

10. Removable Feet: The amplifier feet can be removed as required for rack mount installation.

Remote Control

LCD Display Screens and Functions
Normally, the LCD display will show the status for a number of settings as well as the volume level and a flashing output level bar display.

• Volume Control: Adjusts the output of the system. The volume control should be set to achieve similar volume levels from both the main speakers and subwoofer.
• Subsonic Control: This allows the user to select the frequency at which they wish to cut off the high-pass audio signal.
• Crossover/ Frequency: This allows the user to select the frequency at which they wish to cut off the low-pass audio signal. This feature only available in Sub Mode.
• Crossover/ Slope: This allows the user to select the slope for the crossover. This feature only available in Sub Mode.
• Preset Mode: There are presets for all sat/sub-combinations, such as TV speakers or floor-standing speakers.

Phase Control: This feature is used to adjust the subwoofer’s acoustic phase to match that of the main speakers.

• Night Mode: Limits the dynamic range of the amplifier so the louder context of the source signal is reduced. This feature allows the user to select night mode. Choose enable or disable.
• Auto Off : This feature allows the amplifier to turn itself off when not in use. With the function set to active, the amplifier will monitor its input signal. If no signal is present the amplifier will shut down and go into standby mode. As soon as a signal is present, the amplifier will turn itself back on.
• Mode Select: This allows the user to select a mode. Set values contain: SUB or LFE.
• External Trigger: This allows the user to select and enable the external trigger function. Press and hold the navigation control knob with the power switch in the ON position to change.
• Lock Mode: When this function is active, all settings will be protected until disabled. Values are: ON or Off.
