Important

Read this before connecting the amplifier to AC mains

VMA Series mixer-amplifiers are pre-configured at the factory to operate on either a 115 V or a 230 V AC mains

supply. Before applying power to the unit, please check the rear panel to ensure that the version you have is

correctly set for your local supply voltage.

The MAINS VOLTAGE SELECTOR switch on the rear panel will show either 230 V or 115 V, as shown below.

The warning sticker above the switch will confirm the factory setting.

DO NOT CONNECT YOUR VA SERIES AMPLIFIER TO AN AC SUPPLY

WITHOUT FIRST VERIFYING THE VOLTAGE SETTING.

Introduction

The Cloud VMA120 and VMA240 are cost-effective mixer-amplifiers for use in all types of commercial premises, such as pubs,

bars, hotels and offices. They have been designed to be as simple to install and operate as possible, yet retain a useful range of

configuration options.

The units are mono power amplifiers combined with a simple mixer stage. The two models are identical in terms of facilities,

and differ only in the maximum power output available – 120 W or 240 W respectively. They may be used to drive either low-

impedance loudspeakers directly (4 ohms minimum) or 25/70/100 V-line loudspeaker distribution systems. The two different

types of speaker system cannot be driven simultaneously.

The mixer stage has four stereo line inputs, including one in the form of a 3.5 mm jack socket on the front panel to permit

the easy connection of laptops, tablets and similar devices. There are also two microphone inputs. Front panel switches allow

the mics to have priority over music sources, and also for one line input to have priority over the others: this will be useful for

connecting a message store, for example. All user controls are on the front panel.

The rear panel has connections for a music mute control input which can be used to mute all music sources in an emergency,

and also a balanced auxiliary output to allow additional power amplifiers to be slaved.

The VMA120/240 have several internal PCB jumpers which may be moved to reconfigure certain aspects of the unit's operation.

These include enabling microphone phantom power and LF filtering, selection of priority triggers as pre or post the level

controls, and a selectable hi-pass filter for use with 25/70/100 V-line systems. See "Table of internal jumpers" on page 10 for

a full list of functions.
