2. The equipment may be used in dry rooms only.
3. The equipment may be opened, serviced, and repaired by authorized personnel only. the equipment contains no
user-serviceable parts.
4. Before connecting the equipment to power, check that the AC mains voltage stated on the supplied AC adapter is
identical to the AC mains voltage available where you will use the equipment.
5. Operate the equipment with the supplied 20-V AC adapter. Using adapters with a DC output and/or a different out-
put voltage may cause serious damage to the unit.
6. If any solid object or liquid penetrates into the equipment, shut down the sound system immediately. Disconnect the
AC adapter from the power outlet immediately and have the equipment checked by AKG service personnel.
7. If you will not use the equipment for a long period of time, disconnect the AC adapter from the power outlet. Please

8. Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc. and do not ex-
pose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock.
9. To avoid hum or interference, route all audio lines, particularly those connected to the microphone inputs, away from
power lines of any type. If you use cable ducts, be sure to use separate ducts for the audio lines.
10. Clean the equipment with a moistened (not wet) cloth only. Be sure to disconnect the AC adapter from the power
outlet before cleaning the equipment! Never use caustic or scouring cleaners or cleaning agents containing alcohol
or solvents since these may damage the enamel and plastic parts.

accordance with local waste disposal rules.
The AS 16x12 from AKG is an automatic audio mixer with 16 inputs, 12 outputs, and a crosspoint matrix system for all
audio channels in a 2-U rack mount case. The AS 16x12 provides an RS-232 interface and connections for a number of
remote controlled functions. To create a sound system with more than 16 microphone channels, you can connect sev-
eral AS 16x12s together.
For more details refer to the AS 16x12 Owner's Manual.
1 x AS 16x12
1 x AC adapter
1 x CD-ROM with "LecNet for AKG" software
1 x RS-232 cable
1 x IC AS 8 LecNet expansion cable
1 x 3-in. (7.5-cm) audio expansion cable
1. Install the unit in your 19" rack.
2. If you use only one unit, set the MASTER/SLAVE switch to "MASTER".
To obtain a matrix mixer with 32, 48, or 96 inputs and 12
outputs, you can daisy-chain several AS 16x12s.
1. Set the MASTER/SLAVE switch on the unit in the
highest slot in the rack to "MASTER".
2. Set the MASTER/SLAVE switches on all other units to
"SLAVE".
3. Use the supplied 30-conductor flat cable to connect
the AUDIO EXPANSION IN connector on the master
AS 16x12 to the AUDIO EXPANSION OUT connector
on the first slave and so on. (Refer to fig. 1.)
4. Use the supplied LecNet expansion cable to connect
the EXPANSION IN port on the "Master" to the EXPAN-
SION OUT port on the first "Slave" and so on as shown
in fig. 1.
The supplied IC AS 8 LecNet expansion cable carries the
following signals: main audio output, RS-232RX, RS-232TX, and ground. It also allows you to connect the AS 16x12
together with one or more AS 8/AS 8 TCs and/or DFM 4x4s. Refer to fig. 2 on page 8 for an example.
