manual.
3. Connections and Controls
The BerTTi has various connections and controls located on its
rear and front panels:
| Panel | Description |
|---|---|
| A | Power on/off switch |
| B | 10 A IEC AC inlet |
| C | Right channel speaker positive terminal |
| D | Right channel line level RCA input |
| E | Right channel balanced XLR input |
| F | Right channel speaker negative terminal |
| G | 12 V trigger connection |
| H | Grounding post |
| J | Left channel speaker negative terminal |
| K | Left channel balanced XLR input |
| L | Left channel line level RCA input |
| M | Left channel speaker positive terminal |
| N | Power/standby switch and status LED |
4. Power and Earthing Connection
The BerTTi should be connected to power using the supplied 10 A
power cable. If you experience hum or buzz, you can try using a
good-quality earthed power distribution block or connect the rear
panel ground terminal to an available earth point.
5. Inputs
You can connect the BerTTi to any preamp output using
good-quality standard RCA cables or balanced XLR cables. Please
note that only one input type can be used at a time, and switching
between input connection types is not supported. Do not attempt to
use both the RCA and XLR inputs simultaneously to avoid damage to
connected equipment.
6. Connecting to Loudspeakers
To connect the BerTTi to loudspeakers, use good-quality
loudspeaker cables terminated with 4 mm banana plugs. If you prefer
to use spade-plug-terminated cables, unscrew the BerTTi’s
loudspeaker terminals. While bare wire can be used, it is not
recommended.
7. Power On/Off
Use the power on/off switch located on the front panel to turn
the BerTTi on or off.
8. 12 V Trigger
The BerTTi includes a 12 V trigger input. You can connect
compatible devices with a 12 V trigger output to achieve
simultaneous power on/off from standby mode. When connected, the
front panel button LED will turn yellow, and once triggered, it
will change to purple.
9. Placement
Please refer to the user manual for information on optimal
placement of the BerTTi.

8 Power on/off
With all cable connections successfully made and the volume on connected preamps set to zero, switch the rear-panel power button to `on’ and depress the front panel button to switch the unit from standby mode to `on’. The front panel LED will turn from green (standby) to cyan (on), once the BerTTi has performed its safety check. BerTTi is ready for use and the preamp volume can now be carefully increased for playback. The BerTTi consumes very little energy in standby mode and if desired, can be left switched `on’ at all times.

10 Placement
The BerTTi benefits from extensive casework ventilation, plus a cooling fan for more demanding environments. Always ensure the BerTTi is used in a well-ventilated setting, away from direct sunlight and heat sources, with sufficient space (at least 10 cm) around the unit. The BerTTi has internal thermal protection which increases the speed of the cooling fans if excessive temperatures are reached. Should this occur, check the BerTTi has adequate ventilation and/or reduce the volume level until the unit has cooled and the fans have slowed. It is normal for the unit to become warm when operating. If stacking the BerTTi with other units, it is advisable to place the unit on top of others.
