INTRODUCTION
Large soundsystems have always been challenging and expensive to power using batteries,
until now. AMPLIFIER modules have been developed to be fully optimised for using
batteries as the power source, finally giving event organisers an easy-to-use and affordable
method to reduce their reliance on diesel generators.
The belair AMPLIFIER module is a battery powered audio amplifier available in two
versions:
●F1K0 - Four 1000W outputs
●T2K0 - Two 2000W outputs

SAFETY
General Safety Instructions
DO NOT place the equipment near heat sources. It is prohibited to place or operate the
equipment in an environment with flammable, explosive gas, or smoke.
DO NOT attempt to replace the internal battery or any other component of the
equipment by anyone other than authorised personnel. There are no end-user serviceable
components.
DO NOT operate in wet conditions. If the equipment becomes wet, please let the unit dry
completely before using.
ENSURE proper ventilation while in use and do not obstruct fan openings. Inadequate
ventilation may cause permanent damage to the equipment.
DO NOT move the unit while operating.
KEEP AWAY from children and pets.
DO NOT insert foreign objects into any ports or openings of the equipment.
If necessary, only dry powder fire extinguishers are suitable for the product.
USE ONLY the original cables designed for the equipment. Belair Technology SA are not
liable for damage caused by third party equipment that may render your warranty invalid.
Replacement cables are available by contacting sales@belairtechnology.com
REDUCE volume of the input source when changing configurations or loading a new
configuration.
Earthing
The AMPLIFIER chassis is electrically bonded to the chassis of the JUNCTION or
RESERVOIR powerstation used to power the module.
User Manual R1.0
4 / 30
When audio equipment is connected using the XLR inputs, the ground of the audio
equipment is bonded to the chassis of all belair products in use.
If the site installation requires grounding of the system to earth with a rod, the grounding
point for the belair TOWER should be the JUNCTION where an earthing stud is available on
the back panel.

CARING FOR YOUR EQUIPMENT
Regularly clean the air intake filters at the rear of the module - the covers can be popped
off with a small flat screwdriver.
The front filters can be removed and cleaned by removing the top cover.

INSTALLATION
It is recommended to install all belair equipment in suitable 19-inch enclosures. The rear
mounting kit should be used at all times to avoid stressing the front panel flanges.

USING THE EQUIPMENT
Turning on
Connect the DC power cable between the JUNCTION and the AMPLIFIER with the
JUNCTION turned off. Fully turn the collar locking mechanism (clockwise) to ensure proper
contact.
Turn on the JUNCTION and any connected RESERVOIRS by pressing the central power
button.
Turn on the AMPLIFIER by pressing the central power button.
The channel monitor LEDs (on the left side of the front panel) will be lit immediately.
The power switch LED will be lit blue once the amplifier is ready - this takes around one
minute after connecting the power source.
If the amplifier is turned off and on again, it will again take around one minute for the
outputs to be active.

Audio inputs and link
The XLR audio inputs are balanced +4dBu level and the source must be capable of
providing this level to guarantee the full rated power of the amplifier. If using a source with
RCA or jack output, we recommend using an Active Line Driver between the source and the
amplifier to boost the signal and convert the single-ended signal to a differential signal.
The audio link is passive with a 100Ω resistance between input and output so that even if
power is lost to one amplifier, downstream amplifiers will continue to receive the signal.
Note that daisy-chaining the audio between multiple amplifiers is only possible if using the
XLR inputs and not the USB source.
Speaker outputs
The speaker outputs are Speakon™ 4-pole connectors. Do not attempt to bridge the loads.

CONFIGURING THE DSP
The AMPLIFIER contains a digital signal processor (DSP) that is used to control the audio
signal from the source (e.g mixer) to the loudspeakers.
The DSP performs the following principal functions:
●Volume control
●Signal routing
●EQ
●Crossover
●Compression/Limiting
The DSP is configured using the miniDSP 2x4 HD app. This can be downloaded from
minidsp.com for MacOS and Windows at the following address:
https://www.minidsp.com/products/plugins/2x4-hd-plugins/2x4hd1-detail
This manual gives an overview of the most important functions of the DSP; a full
description can be found at the following address:
https://www.minidsp.com/products/minidsp-in-a-box/minidsp-2x4-hd
Connecting to the DSP
Install and open the miniDSP 2x4-HD app on your computer.
With the AMPLIFIER on, connect your computer to the front panel USB connector using the
supplied cable USB-A to USB-B cable.
Click ‘Connect’, located in the top right corner.
A dialog box will open to confirm successful connection.
If the below dialog box appears, ensure that all audio inputs are muted or very low before
selecting ‘Synchronize Config’ or ‘Restore Config’.
