design – allow the OTO Phono SE Signature to produce impressively extended
and controlled bass.

Materials and component quality
Please take care when unpacking your OTO Phono SE Signature Integrated
Amplifier. Choose a clean, clear location to unpack your unit. Be aware that the
amplifier is very heavy; before attempting to unpack or lift the unit, check the weight
and if necessary use more than one person so that it can be moved safely and
easily.
We recommend that you retain and carefully store all of the original packing
materials, in case transportation / shipping is required at a later date.
Select a suitable location for the unit. This should be a dry, dust free and level area,
preferably shielded from direct sunlight and free from vibration. Also ensure that the
location is stable and capable of carrying the weight of the unit.
A suitable mains power outlet must be close to the location; power cords must not be
pulled or stretched tightly in an attempt to reach a wall socket. If the power cord will
not easily reach the socket, choose a closer location!
Please ensure that adequate ventilation for the unit is provided, and that airflow
through any ventilation slots in the unit is not restricted. We recommend a distance of
at least 30cm free space is maintained above the unit. Please also remember that
valve equipment operates at extremely high temperatures, so a position that is
inaccessible to any children or animals is essential.
