3. GETTING STARTED
3.1 UNPACKING MAESTRO
1. Take MAESTRO out of the packaging and check whether MAESTRO or the
individual parts exhibit damages. If this is the case, do not use MAESTRO.
Should you detect any damage, contact your dealer or sonoro audio GmbH
customer support immediately.
2. Check to make sure that the delivery is complete (see chapter “Scope of delivery”).
3. Place MAESTRO at a suitable location. If you want to put your MAESTRO on a
natural wood surface, please make sure that it is suitable. On oiled and waxed
surfaces, stains may occur.
4. Remove the protective film from the display.
3.2 INSERTING THE BATTERY IN THE REMOTE CONTROL
1. Open the battery compartment cover on the back of the remote control by turning
it anticlockwise using a small coin.
2. Insert the supplied batteries (CR2032, 3 V) with the label (+) side up.
3. Replace and close the battery compartment cover by turning the cover clockwise
using a small coin.
Do not block the infra-red sensor on the MAESTRO and the infra-
red transmitter on the remote control during use.

3.3 USING THE ANTENNAS
1. The scope of supply contains a cable antenna and a rod antenna.
For optimum radio reception, one of the two antennas must be used.
2. Screw the desired antenna located on the back of MAESTRO to the FM/DAB
antenna connector.
For good FM/DAB radio reception, the two ends of the cable
antenna should form a ‚T‘ (dipole) with the connection cable.
A: Recommended alignment for FM
B: Recommended alignment for DAB
For even better reception, connect MAESTRO to a suitable house
antenna.
3. If you are using the cable antenna, unfold the cable antenna and align the antenna
so that you have the best possible reception.
4. If you are using the rod antenna, pull the rod of antenna apart and align the antenna
so that you have the best possible reception.
5. Screw the desired Wi-Fi antenna located on the back of MAESTRO to the WiFi
antenna connector. Lift Wi-Fi antenna upwards.
6. If you want to connect MAESTRO to your network using an Ethernet cable, connect
an Ethernet cable from LAN port on the back of MAESTRO to your router.

3.4 SPEAKER CONNECTIONS
NOTICE!
Risk of damage!
• Disconnect the power plug from the power outlet before
connecting the speakers.

Connecting the speaker cables
1. Remove approximately 10 mm of insulation from the end of each speaker cable.
Then, twist the bare wires of the cable firmly together.
2. Unscrew the knob.
3. Insert one bare wire into the hole in the side of each terminal.
4. Tighten the knob to secure the wire.
Using a banana plug
1. Tighten the knob.
2. Insert the banana plug into the end of the terminal.
When connecting the speaker cable, take notice of the followings:
• Do not let the bare wires of the speaker cable touch one another.

SUBWOOFER
(L) (R)
3.5 CONNECTING PRE OUT JACKS / 2.1 SYSTEM
The pre-outs allow you to connect active subwoofers, another power amplifier, mixer,
recorder, etc.
The following illustration shows how to connect an active subwoofer to MAESTRO.
Select the option 2.1 System in the EQUALIZER menu. Then choose at MAESTRO the
same crossover frequency as on your active subwoofer.
MAESTRO allows you to select the following crossover frequencies:
60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 110Hz, 120Hz, 140Hz 160Hz and 180Hz.
Choose a low frequency, e.g. 60Hz, for very large subwoofers and higher frequencies for
smaller subwoofers. Follow the instructions and recommendations of your subwoofer.
Select one of the crossover frequencies and confirm with the „OK“ button.
The speakers connected to the MAESTRO (L and R) are then operated via a
Linkwitz high pass filter 2nd order.
This has the advantage that the L and R speakers are relieved of low tones, and the
entire 2.1 system gains dynamic and maximum volume.
The volume knob on the active subwoofer adjusts the desired bass volume.
Ideally you start with a very low volume and then increase slowly, until the subwoofer is
just heard.
Adjusting the volume, loudness and tone on MAESTRO has effect
on the PRE OUT jacks.
