3.2 Installation
The SM Pro Audio ADDA 192-S can be used stand alone on your desktop or installed into “one”
standard 19” compatible audio rack-mount unit space (rack ears sold separately).
Desktop installation - Simply find a suitable location to place the unit on your desktop. Keep in
mind that you will need easy access to the front panel controls and adequate access to
accommodate your cable connections.
Rack installation - Please remove all cables (including power) before installing the ADDA 192-S
into your audio rack.
Sturdy rack mounting ears (optional accessory purchase) can be attached to each side of the
ADDA 192-S to allow for easy rack installation. Mount the ADDA 192-S into an available rack-
space position and secure with rack-mount bolts/screws.
* Note: Please take into consideration ventilation of your equipment. A well-ventilated equipment
rack will ensure optimum operation and longevity of your equipment. It’s often a good idea to
leave 1 free rack-bay position between your equipment to allow adequate ventilation.
3.3 Mains Voltage & front panel power switch
Mains Voltage
Important Note: - Before you connect your ADDA 192-S to the mains power supply, please make
sure that your local voltage matches the voltage required by the included power supply.
The ADDA 192-S has an external power supply. Each ADDA 192-S is
shipped to the end user destination with the appropriate voltage of
your mains power supply in mind.
Power on/off switch
The ADDA 192-S’s power switch can be found on the rear panel. To enable power to the ADDA
192-S or ‘turn on’, simply place the power on/off switch into the on position.
* Note: When the unit is powered on, one of the front panel sample rate mode LED’s will
illuminate to indicate the ADDA 192-S’s operational state as ‘on’ (and of course the sample rate
mode status) and ready for operation.
To power down or ‘turn off’ the ADDA 192-S, simply place the power on/off switch into the off
position.
* Note: It’s always good practice to protect your ears, and other audio equipment by taking
appropriate care when powering up any audio equipment. Being aware of your gain structure,
and performing a structured power up sequence with your equipment will help to avoid
unexpected audio signals bursts. It’s a good idea to power up devices in sequence from the start
of the signal chain to the end of the signal chain.
