Frequently Asked Questions - ZX1-SUB BOSCH

How do I connect the ZX1-SUB subwoofer to my system?

Use a Speakon NL4 cable. Connect the amplifier output to pins 1+ and 1- of the subwoofer's NL4 connector. Ensure correct polarity for proper low-frequency performance.

Can I use the ZX1-SUB outdoors?

No. The ZX1-SUB is not weatherproof. Never expose it to rain, water, or high moisture. Use only in dry, indoor environments.

What is the recommended high-pass filter for the ZX1-SUB?

For optimal performance, apply a high-pass filter at 38 Hz to protect the woofer from subsonic frequencies and prevent over-excursion.

How do I mount a full-range speaker on top of the ZX1-SUB?

Insert a 35 mm (1-3/8 in) speaker pole into the cup on top of the subwoofer. Ensure the pole is no longer than 1.2 m (4 ft) and the top speaker weighs no more than 11.3 kg (25 lb).

What is the maximum SPL of the ZX1-SUB?

The maximum measured SPL is 127 dB at 1 meter using broadband pink noise at the rated peak power.

Can I daisy-chain multiple ZX1-SUB subwoofers?

Yes. Use the second NL4 connector (parallel output) to link additional subwoofers. The nominal load per amplifier channel will be 6 Ω for one subwoofer and full-range combination, 3 Ω for two. Do not exceed the amplifier's minimum load.

How do I clean the ZX1-SUB enclosure?

Use a dry cloth only. Do not use water, solvents, or abrasive cleaners. Ensure the grille is dry before use to avoid corrosion.

What are the dimensions and weight of the ZX1-SUB?

Dimensions: 400 x 444.5 x 457.2 mm (15.75 x 17.5 x 18 in). Net weight: 19.8 kg (43.6 lb). Shipping weight: 25.4 kg (56 lb).

Is the ZX1-SUB compatible with all amplifiers?

Yes, with any amplifier that can drive an 8 Ω nominal load and deliver sufficient power. For optimal performance, use an amplifier rated for 400-800 W continuous per channel into 8 Ω.

What should I do if the subwoofer produces no sound?

First, check the amplifier and signal chain. Then verify the Speakon connection is secure and wired correctly (pins 1+ and 1-). Use a known working test speaker to isolate the problem. If the test speaker works, the issue is in the subwoofer or its cable.

Tripod and Floor Monitor Operation

Floor Monitor

Electro-Voice Zx1 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 that 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 Zx1 speakers include 35 mm (1-3/8 in) 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 that the speaker stand is placed on a flat, stable surface and be sure to fully extend the legs of the stand. Do not try to make the stand "taller" and compromise its structural integrity.
• Route cables and position the stand so that 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.
• Do not attempt to suspend more than one speaker on a stand designed for a single speaker.
• Unless you are confident that you can safely handle lifting the weight of the speaker onto the stand, ask another person to help you place it.
• Tighten the set screw to minimize rattling and to prevent the speaker from rotating during use.

Pole Mount

Electro-Voice Zx1-Sub speakers include 35mm (1-3/8 in) pole mount cups to allow mounting a full range speaker above it. Make sure to:

• Use a speaker pole that is no longer than 1.2 m (4 ft) and mount a speaker weighing no more than 11.3 kg (25 lb).
• Check that the Zx1-SUB is placed on a flat and stable surface.

Suspending Zx1 Loudspeakers

Electro-Voice Zx1 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 separately). 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. Electro-Voice strongly recommends that Zx1 speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that Zx1 speakers are safely installed in accordance with all such regulations. If Zx1 speakers are suspended, Electro-Voice strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. There are instruction sheets for each EV Suspension and Array Kit that should also be consulted prior to suspending speakers.

Rotating the 90° Horn

The 90^ version of the Zx1 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. The 100^ version of the Zx1 has the same coverage pattern in both the horizontal and vertical planes, so rotating the horn will not change the coverage pattern.

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.

Rotating the Logo

All versions of the Zx1 (except the Zx1-Sub) allow for the logo badge to be rotated, if desired. The logo badge is square and can be rotated in 90^ increments.

To rotate the logo badge, follow the steps below:

1. Using your finger or a flat-edge screwdriver (using care not to scratch grille), grip/pry under the logo badge.
2. Pull the logo badge outwards from the logo recess until it fully clears the front surface of the grille.
3. Rotate the logo badge, in 90° increments, to the desired orientation.
4. Release the logo badge and let it "spring" back into the logo recess.

Troubleshooting

Problem Possible Cause(s) Action
1. No Sound Amplifier	Connect a known working test speaker to the amplifier outputs. If there is no sound, check that all the electronics are on, the signal routing is correct, the source is active, the volume is turned up, and so on. Correct/repair/replace as necessary. If there is sound, the problem is in the wiring.
	Wiring Verify that you have connected the correct wire pairs to the amplifier. Play something at low level through the amplifier (for example, from a CD player or tuner). Connect the test speaker in parallel with the malfunctioning line. If the sound level has gone or is very weak, the line has a short in it (possibly a severe scrape, pinch, or staple puncture). If the sound level is normal, the wire is open (possibly a cut wire or a missed connection). Using the test speaker, move down the line and test each connection/junction until you find the problem and correct it. Observe proper polarity.
2. Poor Low Frequency Response	Speakers wired out-of-polarity	When two speakers are connected out of polarity, the low frequencies will cancel each other acoustically. Carefully observe the wire markings or tracers on your speaker wires. Verify that the amplifier (+) terminal is connected to pin 1+ of the NL4 connector and the amplifier (-) terminal is connected to pin 1- of the NL4 connector.
3. Intermittent output such as crackling or distortion	Faulty Connection Check all connections at amplifier and speakers to ensure they are all clean and tight. If the problem persists, it may be in the amplifier or wiring. See Problem 1 above.
4. Constant noise such as buzzing, hissing, humming	Defective amplifier or other electronic device	If the noise is present but no program material is playing, the likely cause is the signal chain in the electronics. Evaluate each component as necessary to isolate the problem.
	Poor system grounding or ground loop	Check and correct the system grounding, as required.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or Electro-Voice distributor.
