Bosch, Dynacord and Electro-Voice

Commercial audio solutions by application

Background music, announcements, paging and zone control for cafes, restaurants, shops, supermarkets, gyms, offices, schools, hospitals, auditoriums and outdoor spaces. Each example has a layout drawing, the speakers and the amplifier, with every product sold by ESCO in Pakistan.

How a commercial sound system works

Every commercial sound system has the same four parts. Once you know them, every drawing on this page is easy to read.

Sources

Where the sound comes from: a phone or streaming player, the TV, a microphone, a call station for announcements.

Mixer and zones

Decides what plays where and how loud. A small place has one zone. A restaurant with a terrace, or a gym with a studio, needs a zone each, so one can be quiet while another is loud.

Amplifier

Gives the power. Commercial systems use a 100 V line: one thin cable runs from the amplifier past every speaker, and each speaker takes only the watts it is set to. Easy to extend, cheap to wire, safe over long runs.

Loudspeakers

Ceiling speakers for flat ceilings, wall speakers for open ceilings and music, columns for speech in echoing halls, projectors and horns for kitchens, outdoors and long distances.

Priority and ducking. When someone speaks into the call station, the mixer lowers the music by itself and raises it again afterwards. Every system on this page does this.

Three system sizes, three brands

ESCO is the authorised distributor for Bosch, Dynacord and Electro-Voice in Pakistan. Every system below is built from these three brands, and every product links to its page on esco.pk.

Simple

Dynacord U Series

One zone. A mixer amplifier with knobs, nothing to program. Music in, call station in, speakers out.

Two zones

Bosch PLENA mixer + Dynacord amplifier

Two zones with their own volume, announcements to either or both, a chime before each call.

  • PLE-10M2 two-zone mixer
  • V600:2 two-channel amplifier
  • PLE-2CS two-zone call station
  • Showrooms, supermarkets, two-floor shops
Multi-zone

Dynacord V Series zone platform

Up to 8 zones, each with its own sources, level, tone and priority. Wall panels for staff, call station for announcements, app control.

  • VZX-8 zone audio platform
  • V600:2 and V600:4 amplifiers (600 W shared across channels)
  • VWP wall panel, VCS-8 call station
  • Restaurants, banquet halls, gyms, hotels
Replaced products. Older Bosch guides show PLENA Easy Line amplifiers (PLE-1ME, PLE-1MA, PLE-2MA), the PLENA matrix (PLM-8M8, PLM-4P220, PRM-4P600), the PLENA All-in-One (PLN-6AIO240) and LB20 and LC2 loudspeakers. The designs still work exactly the same way; the current products are the Dynacord U Series, the Dynacord V Series (VZX-8 with V600 amplifiers) and the Electro-Voice EVID-S, EVID-C and EVID-EC loudspeakers. For networked systems (Dante), the Dynacord IX Series amplifiers are available on request.

Which system for your venue

Background music, public address, paging, announcements, voice alarm and evacuation: the same four parts, sized for the venue. Find your place and jump to the closest example. If the venue is not here, ESCO has done it.

Voice alarm and evacuation. Where the fire code or the building owner requires certified voice evacuation (EN 54-16, EN 54-24), the commercial systems on this page are not enough. ESCO supplies and installs Bosch PAVIRO and PRAESENSA, which also carry background music and paging, so one system does everything. Ask us which one your building needs.

Cafe, coffee shop or small bar

1,000 to 2,000 sq ft1 zone

What the place needs. Warm background music the whole day, a little louder in the evening. One announcement now and then. Open or decorative ceilings, so wall speakers look better than ceiling speakers.

Where the speakers go

  1. 1
    Seating 4 x Electro-Voice EVID-S5.2TB or EVID-S8.2TB wall speakers (two pairs) on the walls, aimed at the tables. Pick S5.2 for a cafe, S8.2 if the music is the main attraction.

15,000 to 20,000 sq ft4 to 8 zones

What the place needs. Background music during dinner, clear speech from the stage for speeches and nikah ceremonies, and separate levels in the lobby and service areas.

Showroom or midsized shop

Choosing the loudspeakers

Pick the speaker by the ceiling and the job, not by the watts. A 6 W ceiling speaker every 12 ft is plenty for background music in an office; a gym needs 8-inch wall speakers with real bass.

How many speakers? As a starting point, one ceiling speaker every 12 to 15 ft for a 9 to 12 ft ceiling, and one pair of wall speakers for every 400 to 600 sq ft of music area. Coverage depends on ceiling height, hard or soft surfaces, noise and what you listen to, so ESCO's Bosch and Electro-Voice certified engineers confirm the count and the placement for your building before you buy.

Choosing the amplifier

Add up the watts every speaker is tapped at, then add 20 percent. That is the amplifier you need. On a 100 V line the cable can run the length of a supermarket without losing power.

Mixer amplifier or power amplifier? A mixer amplifier (U Series) has the inputs, the mixing and the power in one box, for one zone. A power amplifier (V600) only gives power; the mixing is done by the PLE-10M2 or the VZX-8 in front of it. The U Series mixer amplifiers also have a mixed line output, so one can feed a V600 for more power or a second zone.

Questions we hear every week

Can I use my home hi-fi amplifier and speakers in my shop?

For one or two speakers next to the amplifier, yes. For a shop or restaurant, no: home speakers are 8 ohm and lose power over long cables, and a home amplifier cannot run eight of them. A 100 V commercial system runs any number of speakers on one cable, and an announcement lowers the music by itself.

Do I need a separate amplifier for each zone?

Each zone needs its own amplifier channel. One V600:4 gives four channels, so four zones from one box. The VZX-8 decides which inputs go to which channel and how loud.

Can staff change the volume without going to the rack?

Yes. The V Series has the VWP wall panel for source and volume per zone, and an app. The two-zone PLENA mixer has volume per zone on the front. Single-zone U Series systems can have a local volume control on the wall for a room that needs to be quieter.

How do announcements work?

A call station (UCS-1, PLE-1CS, PLE-2CS or VCS-8) sits at the counter or reception. Press, speak, release. The system plays a chime, lowers the music while you talk, and brings it back.

Which speakers survive outdoors in Pakistan?

The Electro-Voice EVID-S5.2X and S8.2TW wall speakers, the Bosch LP1 sound projectors and the Bosch horn speakers. Mount them under a canopy or eave where you can, use weatherproof junction boxes, and keep the amplifier indoors.

Can the same system do prayer-time and evacuation announcements?

Routine announcements, yes, from any system on this page. A certified voice evacuation system (EN 54) for a hotel, hospital, mall or office tower is a different product class: Bosch PAVIRO or PRAESENSA. ESCO designs and installs both.

How many speakers do I need for my place?

Use the drawings as a starting point: they are drawn for typical rooms. Ceiling height, glass, marble, noise and the music you play all change the count. Send ESCO a floor plan or photos and the Bosch and Electro-Voice certified engineers will size the system for free before you buy.

Do you still sell the Bosch PLENA Easy Line and PLENA matrix?

They have been replaced. The Dynacord U Series takes over from the PLE mixer amplifiers, the Dynacord V Series (VZX-8 and V600) from the PLENA matrix and PRM amplifiers, and the Electro-Voice EVID range from the LB20 and LC2 speakers. The designs on this page use the current products.

Free system design by certified engineers

Send a floor plan, a few photos and what you want the sound to do. ESCO's Bosch, Dynacord and Electro-Voice certified engineers will size the speakers and the amplifier for your building, with the layout drawing and the quotation.
