Häufig gestellte Fragen - MS154A ALTO

Wie schließe ich die MS154A an?

Verbinden Sie das Mischpult über ein XLR- oder Klinkenkabel mit dem Combo-Eingang des Lautsprechers. Schließen Sie dann das Netzkabel an und schalten Sie zuerst das Mischpult, dann den Lautsprecher ein. Stellen Sie die Lautstärke am Lautsprecher ein.

Welche Presets stehen zur Verfügung?

Der MODELLER bietet 16 Presets: JAZZ CLUB+SUB, VIRTUAL SUB, STAGE MONITOR, JAZZ CLUB, CONCERT HALL+SUB, DISCO, VOCAL, ROCK & ROLL, FLAT, DRUM KICK, ANTIRUMBLE, CONCERT HALL, ARENA+SUB, LOUDNESS, ROCK & ROLL+SUB und ACOUSTIC.

Wie reinige ich die Lautsprecher?

Verwenden Sie nur ein trockenes Tuch. Keine Lösungsmittel oder Chemikalien, da diese das Gehäuse beschädigen könnten.

Was bedeutet die rote LED?

Die rote LED zeigt SIGNAL/LIMIT an. Leuchtet sie dauerhaft, ist der eingebaute Limiter aktiv, was auf Übersteuerung hinweist. Reduzieren Sie die Lautstärke.

Kann ich mehrere MS154A verbinden?

Ja, Sie können mehrere aktive Lautsprecher in einer Daisy-Chain verbinden. Nutzen Sie dazu den LINE OUT (XLR) des ersten Lautsprechers und verbinden Sie ihn mit dem LINE IN des nächsten.

Welche Anschlüsse hat die MS154A?

Der Lautsprecher verfügt über einen Combo-Eingang (XLR/Klinke) für Line- oder Mikrofonsignale und einen XLR-Ausgang (LINE OUT) zum Weiterleiten des Signals.

1. INTRODUCTION

Thank you very much for expressing your confidence in ▲LTO products by purchasing MS series powered speaker system. The MS series cabinets are specifically designed for using in hi-quality performance site and the precise sound commercial place. It includes five full range cabinets (MS12A, MS15A, MS152A, MS153A, and MS154A). This series uses trapezium configuration which greatly decreases the resonance of the standing wave in the cabinet. These cabinets uses hi-density matrix spray-paint technics and the bottom bracket design which make mounting quickly and Flexibly. The HF compression driver and vented LF for fully professional performance.

The MS powered speaker cabinets include some exclusive innovations such as switch mode power supply and digital power circuitry (in selected modes) that make them the lightest powered cabinets of this kind ever made. The MS full range models include another Alto innovation: The MODELLER. Thanks to this circuitry, users can select 16 different tastes and applications. The 16 kinds of sound presets especially thought for application with or without subwoofer, for voice optimized application, for Disco Music, for Jazz, for Rock & Roll among others.

Enjoy your MS active speaker cabinet and make sure to read this Manual carefully before operation!

Active, Full-range, two speakers. This is the simplest set-up. You do not need a power amplifier in between the mixer and the 2 MS 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 MS active speaker cabinet (with 1/4"Jack or XLR).
2). Connect the power cord to mains.
3). Turn ON your mixer first, then the MS cabinets.
4). Turn up the volume control of the MS 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.

2. QUICK START - ACTIVE SPEAKER CABINETS

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 MS 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 MS active cabinets.
2). Connect the LINE OUT socket of the first MS 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 subwoofers and then a 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 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, two satellite speakers and one subwoofers.

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 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.)
