Last updated: June 28, 2022 03:24. Revision #4967
1. AC Power Socket.
2. Signal Output Sockets - RCA connections used to connect to a line-level input.
Note: Do not connect to a phono-level input.
3. Balance Control - Used to make fine adjustments to the relative output levels of the left and right channels. In the central position the output from
each channel is equal.
4. MM Input Sockets - RCA connections used to connect to a turntable fitted with a moving-magnet cartridge.
5. Ground Connection Screw - If your turntable has a separate grounding lead then connect here. This provides shielding to the tonearm and the
sensitive circuitry in the turntable.

Getting connected
Last updated: June 28, 2022 03:24. Revision #4968
Initial Setup.
Firstly, connect the outputs of your turntable to the MM input sockets on the Alva Solo using high quality RCA interconnects.1.
If your turntable uses a separate ground lead, connect this to the ground screw on the Alva Solo. This reduces any potential hum or2.
buzzing.
Connect the signal output sockets of the Alva Solo to a line-level input on your amplifier.3.
Ensure that the balance control is set to the central position. This can be adjusted later if necessary.4.
Attach the mains power lead securely to the Alva Solo and power on the unit.5.

Auto power down (APD)
Last updated: June 28, 2022 03:24. Revision #4969
The Alva Solo comes set up with Auto Power Down (APD) enabled and will automatically switch to standby mode after 20 minutes of inactivity.
To disable Auto Power Down (APD): If you wish to disable the APD function, then press and hold the power button for 5 seconds when in standby.
This can then be reset to factory defaults by plugging in the mains lead with the standby button held down
