Frequently Asked Questions - Elvis 15.2XLA ALTO

How do I connect a microphone to the Alto Elvis 15.2XLA?

Use an XLR cable to connect your microphone to one of the combo inputs on the rear panel. Ensure the channel volume is set to zero before connecting, then gradually increase to avoid feedback.

Can I use the speaker without a mixer?

Yes, the speaker has built-in inputs for microphones or line-level sources. You can connect a microphone directly, but for multiple sources, a mixer is recommended for better control.

How do I adjust the bass and treble?

Use the EQ controls on the rear panel. Turn the 'Bass' knob clockwise to increase low frequencies, and the 'Treble' knob for high frequencies. Start at 12 o'clock for a flat response.

What is the maximum power output of this speaker?

The Alto Elvis 15.2XLA delivers a peak power of 800 W and a continuous RMS power of 400 W, providing ample volume for medium-sized venues.

Can I daisy-chain multiple speakers together?

Yes, use the XLR link output to connect another active speaker. This allows you to extend coverage without extra mixing equipment.

How do I clean the speaker grill?

Use a soft brush or vacuum with a gentle attachment to remove dust. For stubborn dirt, lightly dampen a cloth with water and mild soap, then wipe carefully. Avoid moisture entering the cabinet.

Why is there no sound from the speaker?

Check that the power is on, the volume is turned up, and the source is connected properly. Ensure the ground lift switch is not engaged. If using a microphone, check the cable and mixer settings.

What type of stand does this speaker fit?

The speaker has a standard 1.38-inch (35 mm) pole mount socket. Use a speaker stand rated for at least 75 lbs (34 kg) to ensure stability.

Is the speaker suitable for outdoor use?

While the speaker is durable, it is not waterproof. Protect it from rain and extreme moisture. Use a cover when storing outdoors.

How can I reduce feedback when using a microphone?

Position the microphone behind the speaker to avoid direct pickup. Reduce the microphone volume, lower the EQ bass if needed, and use the ground lift switch if there is ground loop hum.

1. INTRODUCTION

Thank you for your purchasing one of our ELVIS speaker enclosures. It is just one of the many Alto products that a talented, multinational Team of Audio Engineers and Musicians have developed with their great passion for music. We design all our transducers and cabinets in Emilia-Romagna of Italy, a lowland famous for music and fast cars. In fact, Lamborghini, Maserati and Ferrari are made just a few miles away from our design centers. The same area has a long tradition in designing and manufacturing some of the world's best professional transducers. Your ELVIS speaker cabinet is capable of very high sound pressure level and it has been created to give you a performance that is better than any loudspeaker in this range. They are flexible in their passive and active configurations and can be used with single and multiple subwoofers.

Enjoy your ELVIS speaker and make sure to read this Manual carefully before operation!

Passive, Full-range, two speakers. This is the simplest set-up. You just need a mixer and a stereo amplifier. It is good for small club gigs, disco, etc.

Make all initial connections with all the equipment powered off, and ensure that all the main volume controls are turned down completely.

1). Connect one side of the speaker cable to the Output CHA/CHB or Binding Post of your stereo power amplifier and the other side to the Input socket of your Elvis speaker cabinet.
2). Complete other connections as illustrated.
3). Turn on your mixer first, then the stereo power amplifier.
4). Turn up the volume controls of your amplifier to about 70%.
5). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to manipulate the output level.
6). After use, turn off your stereo power amplifier first, then the mixer.

2. QUICK START - PASSIVE SPEAKER CABINET

If you use a powered mixer for the passive speakers, it is no need to use an amplifier. make sure all the main volume controls of your power mixer are turned down completely.

1). Connect one side of the speaker cable to the SPEAKER OUT of your powered mixer and the other side to the Input socket of your Elvis speaker cabinet.

2). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to manipulate the output level.

3). After use, turn down of the Main Mix Level control first, then turn off the powered mixer.

Passive, Full-range, four speakers. It is similar to the first set-up but four speakers are connected instead of two.

1). Follow the same steps as described above.
2). Connect the THROUGH socket of the first Elvis cabinet to the INPUT socket of the second Elvis cabinet.

NOTE: Every time you connect Elvis cabinets this way your parallel them to the output of the amplifier that will read half of the impedance of one speaker.

Passive two subwoofers and two satellite speakers. With this example, the stereo amplifier drives both the subwoofers and the satellites. In this case we do not call them full-range anymore because they receive a signal from the subwoofer that is already xovered at 125 Hz. In this way, the high energetic content of the low frequencies is limited to the subwoofer and the satellite's woofer act like a mid-woofer.

1). Connect one side of speaker cable to the Output CHA/CHB or Binding Post of your stereo power amplifier and the other side to the Input socket of your subwoofer, with the second speaker cable connect the Output of the sub-woofer to the Input of satellite.
2). Complete other connections as illustrated.
3). Turn on your mixer first, then the stereo power amplifier.
4). Turn up the volume controls of your amplifier to about 70%.
5). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to manipulate the output level.
6). After use, turn off your stereo power amplifier first, then the mixer.

Active, Full-range, two speakers. It is similar to the passive example but you do not need a power amplifier in between the mixer and the 2 ELVIS speakers. Make all initial connections with all the equipment powered off, and ensure that all the main volume controls are turned down completely.

1). Connect one side of the signal cable at your mixer into the Main Output Left / Right (with 1/4"Jack or XLR) and the other side of the cable in to the Line Input (COMBO) of your ELVIS active speaker cabinet (with 1/4"Jack or XLR).
2). Connect the power cord to mains.
3). Turn ON your mixer first, then the ELVIS cabinets.
4). Turn up the volume control of the ELVIS cabinets.
5). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to reach the desired output level.
6). After use, turn off your active speaker cabinets first, then the mixer.

Active, Full-range, multiple speakers. This solution is particularly flexible when you have a large stage and for fixed installations where you want to send the same signal to different zones like in a Bar, Pub, Restaurant, Church, etc. Each ELVIS cabinet has its own volume control so you can adjust different volumes in different zones.

1). Follow the above steps connecting the MAIN OUTPUTS of the mixer to the LINE INPUTS of 2 Elvis active cabinets.
2). Connect the LINE OUT socket of the first ELVIS cabinet to the LINE IN socket of the subsequent piece. You can connect as many speakers as you wish in this way.

Active, two satellite speakers & two subwoofers. In this example, the mixer is connected to the ELVIS subwoofers and then a 125 Hz xovered line signal is sent to the respective satellites. In this way, the high energetic content of the low frequencies is limited to the subwoofer and the satellite's woofer act like a mid-woofer. As a consequence the satellites built-in amplifier is not stressed by low frequency content.

1). Connect one side of signal cable at your mixer into Main Output Left / Right (with 1/4" Jack or XLR) and the other side of the cable into the Left / Mono Input (COMBO) of the ELVIS active subwoofers; with the second signal cable connect the Left/Mono Line Output of the subwoofer (Stereo / Mono-Jack or XLR) to the Line input (COMBO) of the active satellite (with Stereo - Jack or XLR).
2). Connect the power cord to mains.
3). Turn on your mixer first, then the active speaker cabinets.
4). Turn up the volume control of the active speaker cabinets.
5). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to manipulate the output level.
6). After use, turn off your active speaker cabinets first, then the mixer.
