and reliability you should study these instructions for use carefully. Warning
of a hazard for the user, the unit or possible misuse Important notice
Safety instructions
AC outlet voltages vary from country to country. Before connecting to the mains, make sure that the voltage in your area meets the voltage requirements printed on the power supply. The power supply is used to connect/disconnect the unit from the mains. Make sure that the power supply is easily accessible at all times. Never handle the device, the power supply while your hands are wet or damp. Avoid letting liquids enter the device or the power supply. Never place any item containing liquid, such as a flower vase on or near the device. Never spill any liquid on the device or the power supply. Never place any naked flame sources, such as lighted candles on or near the device. The product shall not be used in damp or wet locations, next to a bathtub, sink, swimming pool or any other similar conditions.
Connectors
- Make all connections except the connection to the headphone and USB whilst the unit is disconnected from the mains.
- Never connect or disconnect the power supply to or from the unit whilst the power supply is connected to the mains. Never use any other power supply than the supplied one, with the exception of dedicated Power Boxes which can replace original power supplies.
- Take care to connect the left and right channels of RCA inputs correctly. The right channel is usually marked red, the left channel black or white.
- Speaker connections for the left speaker are located on the right hand side of rear view above, connections to right speaker are located on the left side. Speaker connectors marked red represent + according indicators on speaker terminal
Mains power connection and methods to switch the unit on and off
Connect the low voltage plug from the power supply to the Power 38V DC socket
of the unit before connecting the power supply to the mains. MaiA DS3 can be
switched on and off by using 2 different methods which are equal in
priorities.
Using front pushbutton to switch on or into standby
The pushbutton on the front panel of the unit alternately turns the power on
or returns it to standby mode. The blue LED on the front panel shows that the
unit is powered on. If a trigger signal is present MaiA DS3 can’t be switched
off by the pushbutton.
Remote power on – triggers
MaiA DS3 can be switched on via other Box Design components when a 12V trigger
voltage is present at the 2.5mm socket marked Trigger Input. Special power-on
cables (polarity ) in diverse lengths are available as accessories. The remote
power-on signal can be relayed to further units via the Trigger Output socket.
When the 12V trigger signal is switched off, MaiA DS3 will also switch off.
Trigger cables may only be plugged into the sockets when the amplifier is disconnected from the power supply and from the mains. Failure to do so may result in damage of the unit.
Line output
A power amplifier, active loudspeakers or an active subwoofer can be connected
to the output sockets marked Var Output.
Fix Line Output
Fix Output connects an analogue record device or a headphone amplifier.
Connection to the speakers
The output terminals accept loudspeaker cables terminated with 4mm Banana
plugs, spades connectors or naked wire.
Phono input
Connect the tonearm signal lead to the Phono input of the amplifier. The MM/MC
switch on the back panel allows to adapt to connected cartridge type. The
earthing wire may be connected to the screw terminal if you encounter hum
problems when using the turntable.
Line inputs
Line level sources (CD player, radio or TV) can be connected to the inputs
marked In 2, In 3 or In 4.
Digital inputs
Sources with a digital output such as TV, satellite/cable receiver or a game
console can be connected to the digital inputs. Optical to In 5 and In 6 and
coaxial to In 7.
Sub output
An active subwoofer may be connected to the output sockets marked Sub Out.
Connecting to a Computer
Connect the USB-input In 8 USB of the MaiA DS3 (unit must be switched on) to a free USB-socket on your computer and turn it on/make sure it is powered on. Select input 8. For Windows® operating systems an USB Class 2 driver (supplied on CD) has to be installed Mac OS® operating systems do not need an additional driver or setup. Linux operating systems include an USB Audio Class 2 driver from Linux Kernel 2.6.35 and higher.
Please note : Connection should be made to an USB-socket of your computer directly. Connecting to USB-hubs or switches can cause problems
24Bit/192kHz playback with Windows® operating systems
For Windows® operating systems a 24Bit/192kHzUSB driver (supplied on CD) has
to be installed. Insert the included CD into the drive of your PC and follow
the instructions. After installing the driver, some settings have to be
checked/done. For example – Windows 10® operating system:
- Control Panel Sound Playback : select Speaker/MaiA DS3 USB 2.0 Audio Out
- Properties Supported formats : make sure nothing is assigned
- Level Sound : setting must be 100
- Enhancements: disable all enhancements Advanced Default Format: set to studio quality 24/192
DSD playback
Playback of DSD files (.dff, .dsf) is possible over USB. Player capable of
playing DSD files is required in your computer. On the front panel are LED´s
which indicate sample rate of DSD playback.
Front panel controls
Input selector
After the unit is powered on, pressing the buttons◄ and ► selects the desired
input. The LEDs show which input is currently active.
Volume
Adjust the volume to the desired level, using the large knob on the front
panel.
Connecting a headphone
Connect the headphones to the ¼“ (6,3mm ) jack socket on the front of the
unit. Once headphone jack is connected into the socket, rear panel outputs are
muted. +6dB button gain of the preamplifier for all inputs is increased by 6dB
if pressed
BT connection
Make sure the antenna is attached to its connector In 9 BT on the back panel
prior using BT.
Only use the supplied antenna!
BT is active only when input 9 is selected. If you want to connect your
device the first time activate the pairing mode by pressing and hold the
button ►(pair) until LED 8 starts blinking. The MaiA is now visible & ready to
pair for 60 seconds.
Pairing with Android devices
Open Settings and turn on BT. Start a Scan for BT devices. Searched devices
will show up. Tap on “MaiA DS3” and confirm presented pairing code on your
Android device. When the connection was successful, the LED of Input 9 lights
up continuously. Now you can play music from your Android device over BT to
MaiA S3.
BT pairing with Apple devices
Tap on Settings and turn on BT. Your device will automatically start searching
for available devices. Tap on “MaiA DS3” and confirm the connection. When the
connection was successful, the LED of Input 9 lights up continuously.
BT pairing with Windows smartphones
Open Settings and turn on BT. A scan for available devices starts
automatically. Searched devices will show up. Tap on “MaiA DS3” and confirm
presented pairing code on your Windows device. When the connection was
successful, the LED of Input 9 lights up continuously. Now you can play music
from your Windows device over BT to MaiA S3. MaiA DS3 can store up to 8 BT
devices. If the memory is full, new connections will automatically replace the
oldest connection. A new connection is only possible if the LED of BT input is
blinking slowly (it indicates that no device is connected). You can reset &
clear the BT module by holding the ◄ button and then turn the unit on. The LED
+6dB will quickly flash & the device will then turn on after the reset is
completed
