BluAmp 90 Owner's Manual – Rockville Audio

Home Stereo Bluetooth Receiver Amplifier w/Mic, Phono, and HDMI Input

Huge Power!

The BluAmp 90 is loaded with 400 watts of peak power and 100 watts continuous RMS! The built-in amplifier is loud enough to maximize a set of bookshelf speakers, ceiling speakers, or wall mount speakers. It also sounds great with tower speakers.

Expandable

This is more than an amplier. The BluAmp 90 will be the control center for your home stereo system or your karaoke system. There are one group of RCA outputs allowing you to connect additional powered speaker(s)/Amplifier(s). The RCA input is selectable as AUX or PHONO so you can use it to connect a turntable or any other analog audio device. The optical input allows you to connect to any digital audio source such as a television. The HDMI ARC input will connect to an HDMI ARC enabled port on any modern television. It also has built-in Bluetooth, USB/SD playback, and coaxial input.

Great for Karaoke

There are two mic inputs along with echo control and mic volume controls, which makes this amp perfect for karaoke parties.

Full Function Remote

The remote control that is included will allow you to access all functions of the receiver quickly and efficiently.

Adjustable Equalizer Settings

The adjustable bass and treble controls will allow you to fine-tune your music to your taste.

Important Safety Instructions

To reduce risk of shock, never open the unit. There are no user-serviceable parts. For service, return the unit to Rockville or take it to an authorized service center.
Do not place this unit near heat sources, expose it to direct sunlight, or expose it to any kind of moisture.
Do not place anything on top of the unit. Doing so will block vents and cause the unit to overheat.

Choosing Compatible Speakers

Speaker Types

Full-Range Speakers:

These are speakers that can produce a full range of sound. They usually come in a 2-way configuration (woofer and tweeter) or a 3-way configuration (woofer, tweeter, and mid-range driver). They can vary in size from 6.5˝ to 15˝. The quantity and type will be determined by the size of the room and the specific requirements of your karaoke set-up. We recommend our KPS or SPGN series of speakers as well as bookshelf and home audio speakers, which can be found at RockvilleAudio.com.

Matching Impedance:

It’s important that you match the impedance of your speakers to your amplifier. The BluAmp 90 has a minimum speaker impedance of 4 ohms; hence, the total impedance of your speakers must not be less than 4 ohms.

Speaker Configurations

1. One 4-ohm speaker attached to each channel.

2. One 8-ohm speaker attached to each channel.

3. Two 8-ohm speakers, in parallel, attached to each channel.

Mic Connections, Echo, Delay, And EQ

1. Connect wired mics (not included) to either one of the ¼˝ mic jacks.
2. Microphone Volume: Adjusts the volume of microphone output.
3. Echo: The echo effect adds a series of repeated, decaying echoes to a sound. Equalizing (treble and bass controls, see below) the delays will change a room’s sound characteristics from one that has reflective surfaces (brighte-rsounding echoes) to one that is totally absorptive (darker-sounding echoes).
4. Equalizer: The bass and treble controls allow the user to make adjustments to these settings, which will affect overall sound output (mics and music).

Using Your Bluetooth-Enabled Device for Karaoke

1. Choose a device to use as your karaoke viewing screen (iPad, iPhone, Android, tablet, or laptop). We recommend using the Rockville IPS20 Tablet/SmartPhone/iPhone/iPad Tripod Stand to support your device. Find it at RockvilleAudio.com.
2. Turn on your device and the BluAmp 90. Pair the two using the Bluetooth feature
3. Next go to www.youtube.com on your device and type the name of the song you would like to sing ( + the word karaoke) into the YouTube search field.
4. Adjust the volume of the BluAmp 90 and microphones as you see fit. Now you’re ready to sing!
