1 Introduction

1.1 Welcome

Thank you for choosing Electro-Voice Q series amplifier. Please take time to consult this manual so that you can understand all the features built into your Electro-Voice amplifier and fully utilize all its performance capabilities.

1.2 Unpacking and Inspection

Carefully open the packaging and take out the power amplifier. Inspect the power amp’s enclosure for damages that might have happened during transportation. Each amplifier is examined and tested in detail before leaving the manufacturing site to ensure that it arrives in perfect condition at your place. Please inform the transport company immediately, if the power amplifier shows any damage. Being the addressee, you are the only person who can claim damages in transit. Keep the cardboard box and all packaging materials for inspection by the transport company.

Keeping the cardboard box including all packing materials is also recommended, if the power amplifier shows no external damages.

CAUTION:

Do not ship the power amp in any other but its original packaging.

When shipping the power amp, make sure to always use its original box and packaging materials. Packing the power amplifier like it was packed by the manufacturer guarantees optimum protection from transport damage.

1.4 Features and Description

Electro-Voice Q series amplifiers offer a package of reliable high output power, high efficiency and legendary pro audio performance. They are the premium choice as system drive for a variety of mobile and club sound systems like e.g. ZX, Tour- X and Phoenix loudspeaker families. Their comprehensive protection system includes circuitry against overheating, overload, short circuit, HF and DC as well as back-EMF and inrush current. Loudspeakers are protected by turn-on-delay relays.

The build-in patented LPN (Low-Pass-Notch) filter compensates for transient distortion in dynamic signals (such as kick- drums) to achieve a higher acoustic output and more punch.

1.5 Responsibility of the User

Speaker System Damage

Q power amps provide extremely high power output that might be dangerous for human beings as well as for the connected speaker systems. High output voltages can damage or even destroy the connected speaker systems, especially, when the Q amplifier is operated in bridged mode. Prior to connecting any loudspeakers, make sure to check the speaker system’s specifications for continuous and peak power handling capacities. Even if amplification has been reduced through lowering the input level controls on the amplifier’s front panel, it is still possible to achieve full power output with a sufficiently high input signal.

Danger at the Loudspeaker/Power Outputs

Q amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. To protect yourself from electric shock, do not touch any blank speaker cables during operation of the power amp.

WARNING:

The terminals marked with are hazardous live and the external wiring connected to these terminals requires installation by an instructed person or the use of ready-made leads of cords.

RF-Interference (FCC Information USA)

1.IMPORTANT: Do not modify this unit! Changes or modifications not expressly approved by the manufacturer could void the user‘s authority, granted by the FCC, to operate the equipment.
