Introduction

The Rockville RPA40BT amplifier is a great option for setting up a karaoke system at home. With its built-in microphone inputs, echo effects, and multiple input options, you can easily connect a TV, microphone, and speakers for a full karaoke experience.

This guide will show you how to:

• Connect microphones to the amplifier
• Set up a TV as an audio source using the optical input
• Adjust volume and effects for the best karaoke experience

Step 1: Connecting a Microphone

The RPA40BT has two microphone inputs on the front panel.

1. Plugging in the Microphone

• Take a microphone and a female XLR to ¼-inch cable.
• Plug the XLR end into your microphone.
• Plug the ¼-inch end into one of the mic inputs on the amp (for this setup, we’ll use Mic 1).

2. Adjusting the Mic Volume

• Raise the Mic 1 volume knob on the amplifier.
• Turn up the channel/zone volume knobs to hear your voice through the speakers.

3. Adding Echo Effects (Optional)

• Adjust the Echo knob to add reverb to your voice.
• The higher you turn the knob, the more echo you’ll hear.

Step 2: Connecting Your TV for Karaoke Music

To play karaoke tracks from YouTube or other sources, you can connect your TV’s audio output to the amplifier.

1. Using the Optical Input

1. Check if your TV has an optical audio output (labeled "Audio Out - Optical").
2. Take an optical cable and plug one end into the optical output of the TV.
3. The other end of the optical cable will light up red when the signal is active.
4. Remove the cap from the optical input on the RPA40BT, then plug in the cable.

2. Setting the Amplifier to Optical Mode

1. Turn the input selector knob on the amplifier all the way to the right to select Optical Mode.
2. Raise the Input Volume knob to ensure the sound is amplified.

3. Adjusting TV Audio Settings

• On your TV audio settings, change the audio output from TV speakers to Optical Out.
• Go to Advanced or Expert Settings and switch the audio format to PCM to ensure the stereo signal is properly sent to the amplifier.

Step 3: Adjusting Sound and Starting Karaoke

1. Adjusting Speaker Volume

• Raise the volume knobs for each channel/zone to hear the TV audio through the speakers.

2. Playing Karaoke Songs

• Open the YouTube app on your TV.
• Search for karaoke versions of your favorite songs.
• Sing along using the microphone, while the music and your voice play through the speakers.
