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. The active models even include a microphone preamplifier and a three-band graphic equalizer.

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.

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.

MIXER

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.

3. QUICK START - ACTIVE SPEAKER CABINETS

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 subwoofers & two satellite speakers. 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.

Active, one subwoofer and two satellite speakers.

This is a very popular combination, especially in small size clubs where there is no need for two subwoofers.

1). Connect one side of signal cable at your mixer into Main Output Left (with 1/4"Jack or XLR) and the other side of the cable into the Left Input of the ELVIS active subwoofer. Repeat for the RIGHT channel. With the second signal cable connect the Left Line Output of the subwoofer (Stereo/Mono-Jack or XLR) to the Line input (COMBO) of the active satellite (with Stereo-Jack or XLR). Repeat for the RIGHT channel
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.

Active, with Microphone and Line Level instruments.

Your Elvis cabinets come with both Line-level and with Microphone Inputs. You can directly connect a microphone into your Elvis cabinet using the MIC input and a keyboard or an electric guitar (you must interconnect a D/I Box if you want to use the guitar) and use the relative level controls as a simple mixer. You can then use the resident 3-bands graphic equalizer to fine-tune your sound. This configuration is good for presentation, meetings, aerobic centers and fashion shows (you can also connect a wireless microphone into the Line input, or for "One Man band" performances.)

3 BANDS EQ

You have three EQ control on your Elvis 2-way active cabinets each providing providing +/-6dB of boost and cut. The signal will be unaffected when the controls or on center position.

- HI

If you turn this control up you will boost all the frequencies above 12 kHz (shelving filter). You will add transparency to vocals and guitar and also make cymbals crispier. Turn the control down to cut all frequencies above 12 kHz. In such way you can reduce sibilances of human voice or reduce the hiss of a Tape player.

- MID

This is a peaking filter and it will boost/cuts frequencies with their center at 2.5 kHz. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments.

- LOW

If you turn this control up you will boost all frequencies below 80 Hz. You will give more punch to bass drums and bass guitar; and you will make the male vocalist more "macho". Turn it down and you will cut all the frequencies below 80 Hz. In this way you can avoid low-frequency vibrations and resonance thus preserving the life of your woofers.

9). RIGHT, input signal on XLR connector.

10). LEFT/MONO, input signal on COMBO connector.

-. For Passive Speaker Cabinets

Please only use the power connectors to make connections with other signal source equipment for the passive speaker cabinets. The power connector has four terminals: 1+, 1-, 2+, 2-.

In our cabinets, only 1+/1- are used to connect the Speaker+/Speaker-, and 2+/2- are not used.

-. For Active Speaker Cabinets

As to these circumstances, audio connections is mostly intended for the signal flow, so, determine the wire configuration according to your real application system and its connecting facility. Normally, you have the following choices:

• Balanced

- Unbalanced
