Explanation of Graphical Symbols

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magni-tude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servic-ing) instructions in the literature accompanying the product.

APPLICABLE FOR USA, CANADA OR WHERE APPROVED FOR USAGE

CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE PLUG TO WIDE SLOT, INSERT FULLY.

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with a dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provid-ed plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use cau-tion when moving the cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-sup-ply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or mois-ture, does not operate normally, or has been dropped.
The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the appa-ratus.

CAUTION: Servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

Introduction

Congratulations and thank you for purchasing the Integrator Series multi-channel power amplifier!

Since the time we started in 1926, ELAC has always striven to achieve the very best!
The Integrator Series multi-channel power amplifier feature a combination of performance, flexibility and control to provide high value and great sound in different amplification arrangement.
The Integrator Series IS-AMP8100, IS-AMP1275 and IS-AMP1650 are DSP can be configured in two speaker output modes: stereo mode and bridged mode.

The multi-channel power amplifier series feature network control.
All models have many DSP tools including level controls, EQ’s, high and low pass filters, limiters to provide flexibility for different applications.
Access to the DSP settings is accomplished via web GUI interface.

Please read and follow the instructions in this guide to assist in proper installation, connection and use of your ELAC multi-channel power amplifier.

Front and Rear Panel Features

POWER LED – Shows the amplifier unit is ON.

STATUS LED – Shows the status of the amplifier unit: Blue – shows the signal is present
Short red – shows the signal is clipping
Solid red – shows the amplifier unit is in protection mode
LINE OUT – These are assignable outputs via the web GUI interface.
LINE IN – Use these RCA connectors to input audio signal into the power amplifier. Depending on the model, the amplifier have 8, 12 or 16 line inputs.
The Line Inputs are assigned to the corresponding Speaker Outputs by default.

12V TRIGGER – Use this connection to ON/OFF control the amplifier unit (5 … 24V DC).
AC MAINS – After all other connections have been made and confirmed, using the included power cord, connect the AC Mains on the amplifier to an AC outlet.
POWER SWITCH – Used to turn ON/OFF the amplifier.

ETHERNET – Using an Ethernet cable, connect the Ethernet port on the amplifier to local network (LAN). The Ethernet port is used for setting up the amplifier through it’s web GUI and for 3rd party control.
RESET – Use this button to reset the IP settings. The reset button on the rear panel of the amplifier will reset the IP settings only. You can reset the other functions of the amplifier via Web interface only (see GUI Controls Defined).
SPEAKER OUT – Using 12AWG (max) speaker wire, connect the speakers outputs on the amplifier to the appropriate speaker terminals. Before connecting the speaker wires, twist the ends of the speaker wire so there are no strays that can cause shorts. See section: Speaker Connections for additional information.

Speaker Connections

The 4 pin connector plugs allows easy connection of two speakers for single ended connec-tion or one speaker for bridged connection.

Use 12AWG (max) 2-conductor stranded speaker wire for speaker connection plugs.
Strip approximately 1/4 to 1/2 of an inch off the ends and twist the strands together so there are no loose ends that can cause shorts.

On the amplifier rear panel, insert one end of each striped speaker wires into the provid-ed plugs and tighten the screws. Ensure that all speaker wires are firmly attached to the plugs.
Match the polarity markings on the rear panel of the amplifier unit with the polarity of the speakers. If the wiring is incorrect then the speakers will be out-of-phase, with a noticeable decrease of in the bass frequencies and and sound performance.
Connect the speaker wires to the appropriate + and – terminals on the speakers. Confirm connection and polarity.

For single ended speaker connection (Figure 3) the speaker impedance should be 4 ohm or 8 ohm.

For bridges speaker connection (Figure 4) the speaker impedance should be 8 ohm.

NOTE: If the Speaker Out senses a short, the amplifier will enter protect mode and ‘Fault’ will appear in the amplifier web page and app. In “Fault” mode, the audio amp will be shut down, but the logic and control will remain on.

To reset the amp, power cycle the amplifier: unplug the amplifier from the wall jack for minimum 30 seconds and then plug it back in. If the amp does not return to normal operation, please contact ELAC at 714.252.8843 or at service@elac.us.

12 Volt Trigger & Ventilation

12V Trigger IN
When a voltage between + 5V DC and +24V DC is sensed at the trigger input the amplifier is turned ON.

12V Trigger OUT
The output trigger has a 12V voltage and 10 mA current.

Ventilation
The multi-channel power amplifier series IS-AMP8100, IS-AMP1275 and IS-AMP1650 require plenty of good ventilation to properly cool and work within the design parameters.

There are thermal sensors to protest the amplifier from overheating. If overheat occurs, the amplifier is entering in compression mode which means, less output power.

Further more, in some extreme overheating cases, the amplifier is protecting it self by turning OFF. If this occurs often, identify the cause and take corrective actions:

do not install the amplifier in a sealed location with poor ventilation
install a fan in the rack

make sure the amplifier(s) are not overloaded with speakers impedances below the recommended minimum impedance
ensure there are no short circuits in the speaker cables or speakers

NOTE: Please, be advised that no more than 2 amplifiers can be stacked together without a 1U rack space or more between them.

Ideal spacing above and below each stack of 4 amplifiers or individual amplifier is shown in Figure 5.
