ELECTRO-VOICE EVID EC4.2

Product overview

The ELECTRO-VOICE EVID EC4.2 is a 4-inch coaxial two-way ceiling loudspeaker from the EVID Entry Ceiling range: 130° conical coverage, 80 Hz - 20 kHz (-10 dB), a front-baffle tap switch for 70 V / 100 V lines or 8 Ω bypass, and a bezel-less magnetic grille.

The EVID-EC4.2 is a complete 4-inch coaxial two-way loudspeaker that offers excellent sound quality and outstanding reliability with first-class aesthetics. A wide 130° pattern from 80 Hz to 20 kHz with 89 dB sensitivity keeps retail, hospitality and office ceilings sounding even. A switch on the front baffle selects 20, 10, 5 or 2.5 W on 70 V or 100 V lines (plus 1.25 W on 70 V), or 8 Ω bypass. The low-profile heavy-gauge steel back can mounts in tight spaces, and the bezel-less magnetic grille, tile rails and mounting ring are all in the box.

Key features

• Bezel-less design with easy-attach magnetic grille
• Front baffle wattage tap adjustment
• Includes tile rail and C-ring for easy installation
• 4-pin Euroblock input with pass-through, up to 12 AWG / 3.3 mm² wire
• UL 1480A, UL 2043, CSA C22.2 No. 205 and IEC 62368-1 certified
• Low-profile heavy-gauge steel back can, 158 mm mounting depth
• Paintable grille; paint cover supplied to protect it while the room is painted

Front-baffle tap selection

The line transformer delivers 1.25 (70 V only), 2.5, 5, 10 or 20 W to the loudspeaker on 70 V or 100 V lines, or it is bypassed for 8 Ω operation. The selector sits on the front baffle, so the level can be set or changed after installation: in some constant-voltage installations the grilles are left off until the final level balance is made.

Fast, secure ceiling installation

Cut a 183 mm hole with the cutout template or a circular cutter. In suspended tile ceilings the C-ring and two pre-punched tile rails spread the load over the T-grid; in sheetrock the C-ring alone reinforces the ceiling. Mounting tabs grip ceilings 12.5 to 38 mm thick, tightened to a maximum of 1.35 Nm, and a secondary safety cable attaches to the safety point on the back.

Side terminal with pass-through

A side terminal cover gives access to a removable 4-pin Euroblock that can be pre-wired and takes up to 12 AWG / 3.3 mm² wire. Speakers can be wired in parallel (pins 2 and 3) or daisy-chained (pins 1 and 4), and a strain relief fitting holds the cable; it can be swapped for a listed flexible conduit fitting through the 22 mm knockout.

Optional grilles

Optional accessories: C-RG-S-BK round magnetic grille, small, black (pack of 6); powder-coated steel, magnetic, with safety tether.

ELECTRO-VOICE EVID EC4.2: frequently asked questions

Is it for 70 V / 100 V systems or low impedance?

Both. The front-baffle switch selects the 70 V or 100 V taps (20 / 10 / 5 / 2.5 / 1.25 W on 70 V) or 8 Ω bypass for low-impedance amplifiers.

What size hole does it need?

A 183 mm cutout, in ceilings 12.5 to 38 mm thick, with 158 mm mounting depth.

How many speakers come in one pack?

ELECTRO-VOICE packages the EVID-EC ceiling loudspeakers in pairs; the pack includes two grilles, the C-rings, tile rails, screws and the cutout template.

Can several speakers share one line?

Yes. The 4-pin Euroblock has a pass-through: wire the next speaker in parallel on pins 2 and 3, or daisy-chain it on pins 1 and 4.

Where can I buy the ELECTRO-VOICE EVID EC4.2 in India?

The ELECTRO-VOICE EVID EC4.2 is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: Background music in retail

Retail with a 100 V or 70 V music system.

Connections

Setup

1. Lay out the grid from ceiling height and coverage angle.
2. Set the tap on each front baffle for the level wanted.
3. Install with C-ring and tile rails.
4. Fit the magnetic grilles.

Tip: Leave the grilles off until the final level balance if levels may change.

Workflow 2: Paging and announcements

Hospitality that need clear speech everywhere.

Connections

Setup

1. Choose square or hexagonal spacing with minimum overlap.
2. Set matching taps on all speakers on the zone.
3. Wire in parallel so a removed plug does not drop the rest.
4. Check the sum of taps against the amplifier rating.

Tip: Parallel wiring keeps later speakers connected if one input connector is removed.

Workflow 3: Suspended tile ceiling

Installers working in drop ceilings with mineral-wool or fibre tiles.

Connections

Setup

1. Cut the 183 mm hole with the template.
2. Fit the C-ring and snap in the tile rails.
3. Fix the rails with the screws.
4. Push the speaker in and tighten the tabs (max. 1.35 Nm).

Tip: If a tile fails, the rail ends fall onto the T-grid and hold the speaker.

Workflow 4: Sheetrock ceiling

Fixed plasterboard ceilings.

Connections

Setup

1. Cut the hole.
2. Place the C-ring behind the hole.
3. Attach a secondary safety cable with 25-150 mm slack.
4. Push in the speaker and tighten the mounting tabs.

Tip: The C-ring spreads the pressure of the hold-down tabs.

Workflow 5: Low-impedance system

Small rooms driven by a conventional amplifier.

Connections

Setup

1. Set the switch to 8 Ω bypass.
2. Apply the 90 Hz, 24 dB/octave high-pass filter.
3. Wire with correct polarity.
4. Set levels at the amplifier.

Tip: Out-of-polarity speakers lose low frequencies: check polarity if bass is thin.

Workflow 6: Colour-matched ceiling

Interiors where the grille should match the ceiling.

Connections

Setup

1. Remove the grille.
2. Spray at 45°, left to right, then right to left.
3. Let it dry and repeat if needed.
4. Refit the grille; use the paint cover while the room is painted.

Tip: No harsh solvents or abrasives.
