Welcome to Your Audiopack pro S4

A Guided Walkthrough from Design to Setup

Congratulations on the purchase of your new Bose Professional AudioPack system.

This page provides instructions for a typical installation. Simply progress through each section to deploy your AudioPack Pro.

To start, we’ll review the features of the AudioPack Pro. Next, we will present our simple design guide. From there we will review what comes with the AudioPack Pro and run through a pre-install checklist, as well as cover best practices for mounting and installation. To finish, we will discuss last steps for configuring your system.

Thank you for choosing the AudioPack Pro from Bose Professional.


Step 1: Download the design guide below:

Design Guide

Step 2: Calculate loudspeaker spacing distance

Step 3: Determine the layout of your loudspeakers with your calculated Loudspeaker spacing distance


Step 1: Carefully cut open the box.

Important note: Make sure the wiring you are using above the ceiling to connect your loudspeakers is plenum-rated if required. If you are not sure what the term “Plenum” means or if it is required in your space please click this link to learn more: What is Plenum?

Step 1: Install feet onto the amplifier

Step 2: Determine Amplifier location

In this case we will be placing the amplifier in the equipment closet located in the corner of the office.

Make sure the planned location is located close to a power outlet.

Step 3: Install Euroblock connectors for later use. Do not plug in power at this point.


Step 1: Pull The Wire

The simplest wiring method is to wire the loudspeakers in a daisy-chain. You will only have one cable located at the amplifier location for easier connectivity. With this method, run the loudspeaker wire from the amplifier location to the first loudspeaker and then to each additional loudspeaker, following the path you measured earlier.

Note: Be sure to leave some extra wire as a service loop for each loudspeaker location.  

If your wiring was installed with each loudspeaker wired directly to the amplifier location, you will have a wire representing each loudspeaker. To connect all these wires to the back of the amplifier, we recommend using a terminal block bus bar so you can wire all the cables to it, with one wire to the amplifier.

Step 2: Mark the mounting screw locations using the FS2SE wall brackets

For each loudspeaker location, line up the wall bracket with the wall and mark the screw location using a pencil.

Note: When choosing an installation location, at least one of the mounting bracket’s attachment points must be secured to a support
structure. Attachment points not secured to a support structure must be secured using appropriate hardware for the installation. Choose
fasteners that are consistent with all local building codes and requirements.

Step 3: Install the loudspeaker brackets and pull the speaker wire through the wall

Drill the marked locations for the loudspeaker bracket. Install the loudspeaker bracket to the mounting locations and drill the loudspeaker wire hole.

Pull the loudspeaker wiring through the wall.

Step 4: Wire and connect the loudspeaker wiring

Trim the loudspeaker wires, allowing approximately 12” (305 mm) below the ceiling for easier servicing. Strip the wires approximately 5/16” (8 mm). Remove the Euroblock from the front of the loudspeaker. With the screws facing up, insert the incoming wire with the positive conductor (usually Red) into the far right opening in the block and tighten the screw. (This will correspond to the + 70/100V terminal.) Insert the negative conductor (usually Black) into the second opening from the right. (This will correspond to the – COM terminal.) If there is a wire to go from this loudspeaker to another loudspeaker, then connect the positive conductor of that wire to the far left opening and the negative conductor to the second opening from the left. Plug the Euroblock connector into the loudspeaker, making sure that it is fully inserted.

Step 5: Install the loudspeaker on the wall bracket

Place the loudspeaker on the wall bracket. Tighten the two side screws slightly. Choose the angle that you need for the loudspeaker and tighten down the wall bracket screws.

Step 6: Remove the loudspeaker grill and set the tap setting to the 16W position

The grille is secured to the loudspeaker by the grille lock. Disengage the grille lock by inserting a small tool through the grille perforation
(no larger than 1.5 millimeters in diameter). While depressing the grille lock, slide the grille away from the loudspeaker to detach it.

Using a slotted screwdriver set the tap setting to the 8W setting for 70V operation and to the 4/8W setting for 100V operation.

If you are unsure what type of voltage you will be using (70V or 100V) a good rule of thumb is that if your are outside of the americas use 100V. This will also determine how you will wire the speaker output of the amplifier.

Step 7: Connect Amplifier Output (70V Wiring option)

If you are using a 70V based system (usually in the Americas) connect the positive wire to the 70V Euroblock terminal and the negative wire to the COM Euroblock terminal.

Step 7: Connect Amplifier Output (100V Wiring option)

If you are using a 100V based system (usually outside of the Americas) connect the positive wire to the 100V Euroblock terminal and the negative wire to the COM Euroblock terminal.

Step 8: Set IZA 190-HZ EQ

This selects the correct EQ setting for all FS2 loudspeakers.

Step 9: Connect Amplifier Power (IEC Cable)
Connect the amplifier power cord to a nearby outlet.

Step 10: Connect input source and set gain

This step will be broken into 5 parts:

Part 1: Switch the power on and turn the Master Level completely counterclockwise.

Part 2: Connect your line level audio source to Input A.

Part 3: Turn the output trim completely clockwise.

Part 4: Play audio from your sound source and turn the Input A gain clockwise until the clipping indicator on the front of the amplifier begins to flash. Then turn the Input A gain counterclockwise a small amount until the clipping indicator stops flashing.

Part 5: Turn the Master Level clockwise until the sound from the loudspeaker reaches the desired level.


Step 1: Connect additional equipment

If your audio solution requires addition sources such as a paging Mic, AUX input, or a Mute switch connect those now. Please see the IZA 190-HZ Installation Guide for additional directions.

Step 2: Clean the work area

Make sure to clean up all tools and extra bits of wire and any additional materials that you may not have used. Wipe down the loudspeaker grills with a damp cloth if installing them has created any marks or dirt on the loudspeakers themselves.
