Introduction

2-Way pendant speakers

The ALTI series are two-way pendant loudspeakers, designed for background and

foreground music applications with open architectures and high ceilings. Typical

applications are big scale retail environments, warehouses and other large open spaces

The elegant construction is finished using high grade materials and fitted with premium

acoustic components. This guarantees clear speech intelligence and a warm and detailed

sound reproduction.

Mounting the speaker is done through a connection cable with two integrated steel cores

for suspending with an additional drop safety. Fixation is made through two snap-hooks

on one end and a dual Gripple® fixation on the other end. The included cable length of 3.5

meters offers possibilities for a wide variety of ceiling heights. An innovatively designed

rear cover of the speaker can be placed after installation and hides the connection and

suspension on the speaker end. The ceiling end connections are covered through a

cable cover.

The 2-way combination with an coaxially mounted 1” soft dome tweeter and is fitted

with a phase plug for excellent off axis performance. The high quality polypropylene

enclosure and acoustic engineering craftmanship guarantees premium performance

for demanding applications.

They come in two different models (ALTI4 and ALTI6) in terms of size and power handling.

A multi-tapping line transformer allows them to be connected to 70V/100V public address

systems with various power settings, while connections in low impedance (16Ω) systems

are also possible.

Precautions

READ FOLLOWING INSTRUCTIONS FOR YOUR OWN SAFETY

• ALWAYS KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE. NEVER

HEAT, MOISTURE OR VIBRATION

• THIS UNIT IS DEVELOPED FOR INDOOR USE ONLY. DO NOT USE IT OUTDOORS

• ONLY USE ATTACHMENTS & ACCESSORIES SPECIFIED BY THE

MANUFACTURER.

• ONLY INSTALL THE SPEAKER IN LOCATIONS THAT CAN STRUCTURALLY

SUPPORT THE WEIGHT OF THE SPEAKER. IGNORING THIS CAN BRING THE

SPEAKER DOWN.

• DO NOT USE ANY OTHER METHOD THAN SPECIFIED TO MOUNT THE

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.

CAUTION

• USE CABLES OF THE RIGHT GAUGE TO CONNECT THE LOUDSPEAKER

• USE CABLES WITH CLEAR COLOR 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 ALTI

All-in-one cable & Gripple® connector

The ALTI speakers come with an unique All-in-one-wire, consisting of two steel cores

for suspending the speaker and two copper conductors for connection of the amplifier

to the loudspeaker. The copper conductors are provided with a colored (red / black) PVC

jacket for polarity indication, while one of both steel cores also is provided with a coloring

(red) for indicating the difference between both cores.

One side of the steel cores is terminated with two snap hooks for instant fixation, while

the other side is having two open ends, which can be terminated through the Gripple®

XP1™ keyless connectors. A standard connection cable with a length of 3.5 meter is

included, while longer connection cables are optionally available. The open-end side

allows shortening of the connection cable (if required).

Depending on the ceiling structure and available fixation or rigging points, the All-in-one

wire can be used in two directions. If for example an eye-bolt is provided on the ceiling

side, the snap hooks can be hung onto the eye-bolt, while the open ends are on the

speaker side and terminated using the Gripple® connectors. If the speaker has to be

mounted on a beamed structure on the ceiling side, the open ends can be fixed around

the beams, while the snap hooks are on the speaker side.

The ALTI speakers are delivered with a ceiling cover, which covers the fixation points

(snap hooks or Gripple® connectors) on the ceiling side, in case a clean finishing is

required. Slide this ceiling cover over the connection cable first, before any connections

or fixations are made.

One steel core of the All-in-one wire is slightly shorter (red marked) which is the main

suspension wire while the other one is the additional drop safety. The main suspension

wire has to be fixed to the central position on the speaker, while the additional drop

safety has to be fixed to one of the other fixation holes. On the ceiling side, both have

to be fixed to independent fixation points.

NOTE

The combination of the All-in-one wire with the Gripple® connectors is tested and

approved for being used with ALTI speakers and with a safety factor of at least 5:1.

Installation has to be done in accordance with the instruction and with local regulations.

Consult your local authorities in case of any doubt. When adjusting the length of the

integrated steel cores, make sure the steel cores remain unharmed.

Above illustrations give an overview how the Gripple® connectors shall be used. Feed-

through the steel wire from one side though the Gripple® connector, and pull it through.

Create a loop with the steel wire around the fixation or rigging point whereto the speaker

should be suspended and then feed-through the steel wire once again through the

Gripple® connector. Pull-through the steel cable on the other end once again. Make

sure the cable is fully fed-through the connector and verify the safe connection and

suspension first.

Connecting the speaker

For connecting the ALTI, the wires coming from the amplifier shall be connected to the

4-pin terminal block connector on the rear of the speaker. Each connection terminal

is implemented twice, allowing direct link-through to other loudspeakers on the same

line. The polarity of the connector is indicated on the label which is attached to the rear

side of the loudspeaker, and displayed in the below drawing.

The selection of the power tapping and whether the speaker will be used in a low

impedance (16Ω) or a constant voltage (70V/100V) system is made by means of a rotary

selector switch. The switch can be rotated in 4 positions A, B, C & D. Each position cor-

responds with a specific impedance / power setting indicated on a label attached to the

speaker, and in the table below.

Once the connections are made and the power taps are correctly set, the cover can be

assembled on the rear section of the cabinet. The cover is designed with a sliding tab

which can be removed, allowing it being assembled after the speaker is connected and

suspended.

Position the cover on the rear of the cabinet, and it will click and latch in position.

Once assembled, the sliding tab can be inserted to the cover and can be slide into

position, offering a nice and clean outlook of the cabinet.
