Introduction

Full range horn speaker 8”

The HS2xx series are 2-way horn loaded loudspeakers which are specifically engineered

to provide a long-throw, full-range sound projection in a wide variety of in- and outdoor

applications.

The HS208MK2 is the 8” model of the HS2xx family consisting of a 8” high-output

woofer and a compression driver with 1.3” voice coil. The compression driver is equipped

with an overload protection and is fitted with a 40° x 40° coverage horn which is coaxially

constructed as one entity with the loudspeaker’s enclosure.

Thanks to the selection of complementary high-quality components which are carefully

matched, the HS208MK2 delivers a wide range, smooth frequency response with a

high efficiency. This ensures an extraordinary clarity of speech and extended frequency

response for music with an RMS power of 150 Watt, up to a maximum power of 300

Watt. The frequency range (-10 dB) starts from 70 Hz up to 20 kHz and the sensitivity

(1W / 1m) reaches 97 dB, while a maximum continuous sound pressure level of 123 dB

can be achieved.

The enclosure is constructed out of multi-layer glass composite material with a durable

scratch resistant EPDM coating. The aluminium front grill is lined with an acoustical

transparent and water eliminating backing.

Two different models are available for low impedance use (HS208MK2) and 100V use

(HS208TMK2). The HS208MK2 is fitted with two heavy-duty SpeakON connectors

with waterproof gaskets which ensures a reliable connection with easy link-through to

other speakers. The HS208TMK2 is fitted with a waterproof connection box containing

a multi-tapping barrier terminal block enabling the selection of different line transformer

power tappings while providing easy link-through to other speakers. This makes the

speakers suitable for outdoor use.

An optional mounting bracket provides a complete solution for installation of the system.

SPEAKER. IF EXTREME FORCE IS APPLIED TO THE SPEAKER, IT COULD FALL

DOWN

• ATTACH A SAFETY WIRE TO THE SPEAKER WHEN IT IS MOUNTED HIGH UP.

ONLY USE INDUSTRY-ACCEPTED RIGGING TOOLS AND METHODS

• CAREFULLY CHECK THE UNIT’S CONDITION AFTER UNPACKING.

IF THERE IS ANY DAMAGE TO THE CARTON BOX OR THE UNIT ITSELF,

INFORM YOUR VENDOR IMMEDIATELY.

• ALWAYS FOLLOW THE LOCAL REGULATIONS AND REQUIREMENTS

REGARDING INSTALLATION, SUSPENSION AND CONNECTION OF THIS

LOUDSPEAKER. EVEN WHEN OTHERWISE SPECIFIED IN THIS DOCUMENT.

• THE INSTALLATION OF THIS LOUDSPEAKER SHALL BE DONE BY QUALIFIED

PERSONNEL ONLY.

CAUTION

• USE CABLES OF THE RIGHT GAUGE TO CONNECT THE LOUDSPEAKER

• USE CABLES WITH CLEAR COLOUR CODING INDICATING THE POLARITY AND

MAINTAIN THE SAME POLARITY THROUGHOUT THE WHOLE SYSTEM.

• ONLY USE THE CORRECT AMPLIFIER OUTPUT VOLTAGE AND IMPEDANCE.

EXCEEDING THESE LIMITS COULD CAUSE FIRE OR OTHER FAILURES.

AVOID EXPLOSIONS: DO NOT USE THE SPEAKER AROUND GASOLINE,

THINNER OR OTHER COMBUSTIBLES

• AVOID ELECTRIC SHOCKS: SWITCH OFF THE AMPLIFIER WHEN CONNECTING

THE LOUDSPEAKER

• DO NOT USE THE LOUDSPEAKER FOR AN EXTENDED PERIOD OF TIME AT

DISTORTED SOUND. THIS COULD CAUSE PERMANENT DAMAGE.

Installing the HS208(T)MK2

Mounting

An optionally available U-shaped mounting bracket (MBK208Z) allows safe and secure

installation for the HS208(T)MK2 speakers. It is recommended to use this mounting

bracket for installation of the loudspeakers. If the application requires any other specific

mounting method which is not possible using this accessory, make sure the used

installation method is sufficient strong and the surface whereto the speaker is installed

can support the speakers weight. Always make sure the speaker is secured through an

additional drop safety.

The below drawing shows an explode view how to assemble the mounting bracket to

the speaker.

The mounting bracket includes all parts as listed below. Make sure all these parts are

included with the delivery to ensure a safe and secure mounting of the loudspeaker.

- 1 x U-shaped metal bracket

- 1 x Left side L-shaped mounting ear

- 1 x Right side L-shaped mounting ear

- 1 x 75 cm steel drop safety wire with U-shackle

- 10 x M10x35 mm bolts with nuts + washer

Follow below steps for correct assembly method of the mounting bracket:

1) Mount both (left & right side) L-shaped mounting ears using the pre-drilled holes in

the speakers’ enclosure. Make sure the loudspeaker is positioned in the correct direction

(logo on the grill pointed to the bottom side) with the mounting ears on the bottom side

of the speakers’ enclosure holding the weight of the speaker (as shown in the explode

drawing). Fixation of these mounting ears is done using 6 x M10x35 mm bolts (three

on each side).

2) Fix the U-shaped metal bracket to the mounting position on the supporting structure

(ceiling or wall). The fasteners for fixation to the supporting structure are not included

and shall be chosen according to the surface. (wooden, concrete, brick, ... ). The fixation

shall be done by inserting fasteners through the base of the U-bracket and tightening.

Verify whether the fixation is sufficient strong once assembled before going to step 3.

3) Fix the speaker to the metal U-bracket by inserting two bolts through the center hole

of the U-bracket circular part and the L-shaped mounting ears. Tighten the bolts to

guarantee the speaker is fixed to the bracket.

4) Point the speaker into the desired direction, and insert two additional bolts through

the half circular groove. Once the perfect directional placement has been made, tighten

all the bolts for securing. Make sure the speaker has a minimum down-tilting angle

of 5° to avoid water and humidity flowing in, making it comply to the specified ingress

protection standards.

5) Attach the included drop safety steel wire to one of the provided mounting holes on

the speaker and fix the other side of the drop safety to any point which can structurally

support the weight of the speaker.

Connecting

Connection of low impedance version (HS208MK2):

The connection of the low impedance version (HS208MK2) is made using SpeakON

connectors. Two connectors are provided on the bottom side of the speakers’ enclosure.

The used models are 4-pin types, whereto the signal coming from the amplifier shall

be applied on the +1 and -1 terminals. The second connector can be used for linking

the signal coming from the amplifier to additional loudspeakers, resulting in a parallel

network.

Connection of 100V version (HS208TMK2):

The connection of the 100V (HS208TMK2) version is made in a waterproof connection

box fitted with a barrier terminal block. The speaker can be connected in low impedance

(8 Ohm) or high impedance (100V) systems with different power taps for 120W, 60W

and 30W. The suitable connection method can be chosen through connecting the

corresponding terminals.

The waterproof connection box shall be opened through releasing the four screws of the

cover. Inside this connection box, a 6-pin barrier terminal block connector is located.

The four terminals on the left side are used for connection of the 100V line transformer

power taps with power ratings of 120W, 60W and 30W. The wires coming from the

amplifier shall be connected between the ‘COM’ terminal and the desired power rating.

The two terminals on the right side are used for connecting the loudspeaker in low

impedance mode. The wires coming from the amplifier shall be connected between the

‘COM’ terminal and 8 Ohm terminal.

Above image indicates an example for both a 100V (left side) and low impedance (right

side) connection example.

Once the connection has been made to the required power taps, the cable gland should

be tightened to avoid any moisture entering the waterproof connection box. Then the

cover of the waterproof connection box shall be re-assembled using the four screws.

Mind the polarity markings when wiring the loudspeaker cables.
