Welcome
First off, congratulations! With the purchase of this product you have joined a growing
community of audiophiles who value truthful sound reproduction and who consider neutral
and transparent electronics a cornerstone in this pursuit. We at Mola Mola made it our
primary goal to build electronics capable of passing a signal with no discernible change at
all. Amplifiers make the signal bigger, converters turn the signal from a digital
representation into an analogue one. In all these processes we strive to add nothing and to
remove nothing.
Through our work designing professional audio equipment we have collected extensive
knowledge of how to achieve total freedom from colouration without having to resort to
minimalist circuitry. This allows us to build products that are purist without cutting back
functionality. So we decided that our integrated amplifier should be complete. Very
complete.
The basic Kula Integrated Amplifier has an extremely transparent gain stage and a
programmable routing matrix. The chassis has ample room to fit in optional extras, most
notably a DAC and a phono stage.
The 6 preset buttons are programmable via Bluetooth to access any combination of
channel, processing and routing. In a system with mainly digital sources, the preset buttons
would be programmed to select between them. Vinyl lovers on the other hand might want
to use several buttons to select the same turntable but with different EQ settings to suit
their large collection of historic LP's. All five inputs are switchable between XLR and floating
RCA connections, and all can be assigned as either phono or line.
We wish you a lifetime of musical enjoyment with this product and thank you for your
custom.

Setting Up
Installation
This product relies on free convection of air along the sides and top for cooling. Avoid
placing magazines, books or other objects on top of the product as this acts as thermal
insulation. Installation inside a cupboard is permissible provided at least 30cm (12”) of free
space above the product and 10cm (4”) around the sides is respected. Operation in closer
quarters requires some provision of forced convection (fan) to be installed inside the
cupboard.
Connection
CAUTION: Whenever you are plugging or unplugging cables, make sure that the volume
control is turned fully down. Failure to take this precaution may result in pops or bangs
in the loudspeaker. Use properly shielded interconnects with reliable connectors.
AC Power Input
Connect the supplied power cord to the AC input receptacle on the rear panel. Do not
connect the power cord until all the audio input and output connections have been made.
It is usually best to plug the product directly into a wall outlet. Avoid the use of extension
cords. A heavy duty multi-tap power outlet strip may be used if it and the wall outlet are
rated to handle the total current demanded by the components connected to it.
Your Kula has a universal input power supply, allowing it to operate anywhere from 90V to
240V mains.
If you are going to be away from home for an extended period of time such as a month-
long vacation, it is a sensible precaution to unplug electronic equipment. Do the same as a
precautionary measure during thunderstorms. No amount of surge protection or mains
filtering will save your equipment from a lightning strike in the backyard.
Initialisation procedure
The initialisation procedure only applies when the Kula has the DAC module and network
module fitted. The initialisation procedure will automatically start after the mains power has
been applied will take about one minute. At the start and end of this procedure you might
hear some clicking sounds. During the initialisation procedure the Kula will become visible
in Roon if it is connected to your network. The Kula will also remain visible in Roon during
standby mode. You can power up the Kula during the initialisation procedure and start
