Precautions • If ZxA1 loudspeakers are used outdoors on a sunny day, place the loudspeakers in a shaded or covered area. The loudspeaker amplifiers have protection circuits that temporarily shut the loudspeaker off when extremely high temperatures are reached. This can happen on hot days when the loudspeaker is in direct sunlight. • Do not use ZxA1 loudspeakers in an environment where temperatures exceed +40°C (104°F). • Never expose a ZxA1 loudspeaker to rain, water, or high moisture.
Description Thank you for choosing an Electro-Voice ZxA1 powered loudspeaker system. Please take time to consult this manual to understand all the features built into your Electro-Voice system and fully utilize its performance capabilities. Only to be expected from Electro-Voice, the ZxA1 packs a big-stage punch. Electro-Voice drivers, components, and amplifiers are legendary–all proven at the highest levels of live performance.
System Features ZxA1– 8” Two-Way Powered Loudspeaker The ZxA1 is a compact, powerful, and versatile choice for sound reinforcement and stage monitoring applications — lightweight and durable, with an 800 W amp.
Tripod and Floor Monitor Operation Floor Monitor Electro-Voice ZxA1 loudspeakers may be used as a floor monitor by placing the speaker on the integral monitor angle. Make sure to: • • • Place the speaker on a level, stable surface that is solid and secure. Route cables and position the stand so performers, production crew and audience members will not trip over the stand or cables and pull the speaker system over. Secure cables with wire ties or tape whenever possible.
Tripod and Floor Monitor Operation (cont.) Tripod Electro-Voice ZxA1 speakers include 35 mm (1-3/8 inch) stand mounts to allow mounting on tripod stands. Make sure to: • • • • • • • Check the specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker. Check the speaker stand is placed on a flat, stable surface and fully extend the legs of the stand. Do not try to make the stand “taller” and compromise its structural integrity.
Suspending ZxA1 Loudspeakers Electro-Voice ZxA1 loudspeakers may be safely suspended with single stud fittings by using the MP1 suspension kit, or quickly attached to a truss by using the CA-Zx truss clamp adaptor (both sold seperately). See MP1 or CA-Zx instruction sheets for proper assembly and use. WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead.
Rotating the Horn The ZxA1 allows for the horn to be rotated for more effective coverage if desired. The horn is factory-installed with the 90° coverage in the horizontal plane and the 50° coverage in the vertical plane. To rotate the horn, follow the steps below: 1. Remove the grille screws/grille assembly. 2. Remove the horn screws/horn assembly. 3. Rotate the horn assembly 90°. 4. Secure the horn assembly with the horn mounting screws. 5. Secure the grille assembly with the grille mounting screws.
Amplifier Controls The ZxA1 amplifier has a combination of controls and connectors to ensure the most versatile loudspeaker system. Each component below has a description on the following pages.
ZxA1 Amplifier Controls LIMIT The LED brief blinking indicates the power amplifier is operated at its limits. Short-term blinking is not critical because the integrated limiter keeps distortion under control. Constant lighting of the LED indicates the sound is negatively affected. Reducing the output volume is strongly recommended. MASTER Level control for adjusting the power amp’s overall amplification. The level control affects the volume of the line input and microphone input.
ZxA1-Sub Amplifier Controls LIMIT LIMIT The LED brief blinking indicates the power amplifier is operated at its limits. Short-term blinking is not critical because the integrated limiter keeps distortion under control. Constant lighting of the LED indicates the sound is negatively affected. Reducing the output volume is strongly recommended. LEVEL Level control for adjusting the volume of the subwoofer. The level control affects the volume of both Channels A and B.

Troubleshooting Problem 1. No Sound Possible Cause(s) Action Amplifier Connect a known working signal source to the amplifier inputs. If there is no sound, check all the electronics are on, the signal routing is correct, the source is active, the volume is turned up, and so on. If there is sound, the problem is in the wiring, or a component further up the signal chain. Wiring Verify you have connected the correct wire pairs to the amplifier.
