4.2 Ntinye

The SMP500DSP amplifier can be placed on a flat surface or rack-mounted. Choose a location that is dry, well-ventilated, and away from direct sunlight or heat sources. Allow sufficient space around the unit for airflow.

4.3 Connecting Your Subwoofer

1. Gbaa mbọ hụ na ampagbanyụrụ ọkụ wee wepụ ya.
2. Connect your passive subwoofer to the "Subwoofer Speaker Output" binding posts on the rear panel. Ensure correct polarity (+ to + and – to –).
3. The SMP500DSP supports a single 4-8 ohm subwoofer or two 8-ohm subwoofers.

4.4 Connecting to Your Audio System

There are two primary methods for connecting the SMP500DSP to your audio system:

Method A: Using RCA Line Level Inputs (Recommended)

1. If your receiver or pre-amplifier has a dedicated subwoofer or LFE (Low-Frequency Effects) output, connect an RCA cable from that output to the "Line In" (L or R, or both for stereo) on the SMP500DSP.
2. If your source has stereo RCA outputs, connect both L and R outputs to the "Line In" L and R on the ampna -emegharị ihe.

Method B: Using Speaker Level Inputs

1. If your receiver does not have a dedicated subwoofer output, you can connect the speaker outputs of your receiver to the "Speaker Level In" terminals on the SMP500DSP.
2. Connect the main left and right speaker outputs from your receiver to the corresponding "Speaker Level In" terminals on the ampihe na-eme ka ihe dị ọcha. Hụ na ọ dị mma.
3. You can then use the "Speaker Level Out" terminals to connect to your main left and right speakers, allowing the amplifier to pass through the full range signal.

4.5 Njikọ ike

1. Double-check the AC Voltage Selector switch on the rear panel is set correctly (110V or 220V).
2. Connect the included power cord to the AC Power Inlet on the rear panel of the ampna -emegharị ihe.

• 12V mkpali: If using the 12V trigger, set the "Music On 12V" switch to "12V". The amplifier will power on/off in sync with your connected equipment.

5.2 na-agbanwe olu

Rotate the large control knob on the front panel to adjust the subwoofer's volume level. The digital display will show the current volume setting.

5.3 DSP Control and Settings

The SMP500DSP features onboard DSP for advanced audio customization. Use the control knob to navigate the DSP menu on the digital display. Press the knob to select options and rotate to change values.

Key DSP settings include:

• High-Cut Filter (Crossover): Adjusts the upper frequency limit of the subwoofer. This allows you to blend the subwoofer's output seamlessly with your main speakers. Typical settings range from 30Hz to 150Hz.
• Njikwa usoro: Adjusts the phase of the subwoofer output (0° or 180°). This helps to ensure that the subwoofer's sound waves align correctly with your main speakers, preventing cancellation or reinforcement issues.
• Gain/Level: Fine-tunes the input sensitivity to match the output level of your source device.
• Volume Control Limiter: Sets a maximum volume level to prevent accidental overdriving of the subwoofer.

Refer to the on-screen DSP menu for specific navigation and adjustment instructions.
