1. Opening the Packing and Positioning the Device
Place the box on a table and open it with a cutter or knife, being careful not to damage the
inner box. Take out the inner box and open it. The following items are contained in a
cardboard tray:
one TOSH;
one remote control;
two AAA type batteries;
one 1 V wall adaptor;
two 7-pole male XLR to 3 x female 3-pole XLR adaptors.
If one or more items are missing, contact your dealer.
Remove the TOSH from the cardboard tray and place it on a stable base away from heat
sources. Avoid direct sunlight. Leave ample space around it to the device to ensure
adequate ventilation and for easy connection between the TOSH Bluetooth® module and
your smartphone/tablet.
The TOSH is a highly efficient device; for this reason it does not produce much heat during
its operation. Nevertheless, it is recommended to allow adequate ventilation around the
unit. Furthermore, in all situations in which the remote control is used, it is recommended
to position it so that the infrared signals from the remote control can easily reach its front
panel.
Prevent smoke, humidity, dirt and water from reaching the appliance. Note that any sign of
abuse will void the warranty.
Do not place the appliance on thick carpets or inside a box or inside a mobile, or in close
contact with curtains.

Bluetooth® receiver which allows you to control the TOSH from any smartphone. Keep this
area clear of metal objects.
2) Display. OLED multifunction display. During normal operation, it indicates the selected
source and listening level. When entering the menu, the display shows the selected menu
item and the current value.
3) Encoder. It allows user to access and navigate the menu, select inputs and adjust the
volume. It can be rotated and pressed. Refer to Chapter 7 for more details.
4) Standby LED. When the TOSH is in standby, this LED is lit to indicate to the user that
the device can be turned on using the supplied remote control. It is possible to change the
operation of the LED when the TOSH is in standby from the menu.
5) Activation/standby/mute/menu exit button. Press this button to activate the TOSH
when in standby. When the TOSH is active, a short press activates/deactivates the mute,
unless the menu is active: in this case, a short press will cause the exit of the menu and
the cancellation of any modification to the configuration. A longer press while the TOSH is
active will put it in standby.
