Description

Thank you for purchasing the SMP500 DSP by OSD Audio. This 400W RMS 1000W Peak DSP amplifier has some of the most advanced DSP functions available.

MAKE SURE TO READ THIS INSTRUCTION MANUAL BEFORE TURNING THE POWER ON OR HOOKING UP THIS POWER AMPLIFIER.

Installing Rack Mount Ears

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

Use the supplied three screws to attach the supplied rack ears to the SMP500 DSP 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.
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.

Amplifier Controls and Setup

Front Panel

Power Switch: Turns the amplifier on or off. Amplifier must be on for the trigger or auto sense modes to operate.
16 Character x 2-row Liquid Crystal Display: Shows the amplifier's status, menus and settings and works in conjunction with the turn and push navigation controls and the remote control.
Programming Navigation Control: Used to scroll through the display menus, change setting and program the DSP controller.
For uploading new firmware or updates.

Back Panel

Back Panel - Part 1

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

warning 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.

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.
Voltage Selector Switch: The amplifier can be used on 110~120V (60HZ) or 220~240V (50HZ) 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 located 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 10A rated cable. When the voltage selector switch is changed, the fuse must also be changed to continue to provide protection to the amplifier.

Power Cord Receptacle: The supplied power cord needs to be connected to this receptacle in order for the amplifier to work properly.
Fuse Holder: This is the power fuse access.

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 6.3A 120V or 3.15A 240V fuse.

Before replacing the fuse, disconnect the power cord from the power receptacle.

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.

Volume Control

Subsonic Control: This allows the user to select the frequency at which they wish to cut off the high-pass audio signal.

Subsonic Control

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 Frequency

Crossover / Slope: This allows the user to select the slope for the crossover. This feature only available in Sub Mode.

Crossover Slope

Preset Mode: Compatible with all brands and types of subwoofers.

EQ Mode

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

Phase Control

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.

Night Mode

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.

Auto Off

Mode Select: This allows the user to select a mode. Set values contain: SUB or LFE.

Mode Select

External Trigger: This allows the user to select the enable external trigger function. Press and hold the navigation control knob with the power switch in the ON position to change.

External Trigger

Lock Setting: When this function is active, all settings will be protected until disabled. Values are: Disable or Enable.

Lock Setting

Memory Store: This allows the user to select the memory bank. There are three memory banks.

Memory Store

Memory Recall: This allows the user to recall settings saved using the "Memory Store" function.
