1. Trigger in and out
In order to control the power state from another product (ex: pre-amplifiers or media players) with
trigger control, the SDA-2400 is equipped with 3.5 mm mono mini jack sockets.
• If there is a plug in the “Trigger In” socket with no voltage applied, the SDA-2400 is in standby
mode.
• If a DC voltage of 5-24V or a 50Hz AC voltage of 4-17Vrms is applied, the SDA-2400 will go into
Operate mode.
• “Trigger Out” is for daisy-chaining other SDA-2400s and controlling them all by the same signal.
Connect the control signal to “Trigger In” on the first SDA-2400 and connect its “Trigger Out” to
“Trigger In” on each subsequent unit.
•
2. Power state
As the SDA-2400 has an extremely low power consumption in standby mode, there is no on/off switch
on the front of the product. Instead, power is controlled automatically by the amplifier (this is bypassed
with use of trigger controls.)
“Low Power” means that the SDA-2400 will turn on automatically when it detects a signal on the
7
selected input. If a signal is not detected for around 30 minutes, the amplifier will go into standby mode.
“On” will keep the SDA-2400 permanently turned on.
3-4. Analog unbalanced and balanced input
For connection to products with analog output, you may only connect to one input at a time. The input
sockets are internally connected in parallel, so ALWAYS use EITHER the XLR inputs OR the phono inputs.
NEVER use both at the same time.
5-6. Coaxial input and optical input
For connection to products with digital output, SPDIF and Toslink inputs are available.
7. Input select
Set the selector to the input in use.
8. Loudspeaker connectors
Connect your speakers to Left and Right connectors. The connectors allow for use of banana plugs and
bare wire up to 5mm2.
9. Voltage selector
The voltage selector must be in the correct position for your local mains supply.

10. Mains connector and switch
Be sure that the power cord is inserted firmly in the connector. The mains switch will remove the
amplifier from your mains power.

Connection guide
When connecting the speakers, always connect +
and - from the amplifier to the corresponding + and terminals on the speaker.
Warning: Never run the SDA-2400 in so-called
“bridge mode.” Bridging the speaker output terminals
will damage the amplifier.

Cleaning and maintenance
The SDA-2400 does not require any regular maintenance except to keep its exterior clean. Simply wipe
it with a clean, soft cloth. A small amount of non-abrasive cleaner on the cloth can be used to remove
any dirt or fingerprints. Do not use abrasive cleaners or cleaners containing liquid solvents.
