Permanent hearing loss may be caused by exposure to \ extremely high noise levels. The US. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible exposure to noise level. These are shown in the following chart:

HOURS X DAY

8 6 4 3 2 1,5 1 0,5 0,25 or less

According to OSHA, an exposure to high SPL in excess of these limits may result in the loss of heat. To avoid the potential damage of heat, it is recommended that Personnel exposed to equipment capable of generating high SPL use hearing protection while such equipment is under operation.

The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

The mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.

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!

2. QUICK START - PASSIVE SPEAKER CABINET

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.

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.

3. QUICK START - PASSIVE SPEAKER CABINETS

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.

3. QUICK START - PASSIVE SPEAKER CABINETS

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 (with1/4"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.
