1.
Do not spill any liquids on the equipment and do not drop any objects through the ventilation slots in the equipment.
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
note that the equipment will not be fully isolated from power when you set the power switch to OFF.
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.
11. Use the equipment for the applications described in this manual only. AKG cannot accept any liability for damages
resulting from improper handling or misuse.
1.
The AC adapter will draw a small amount of current even when the equipment is switched off. To save energy, dis-
connect the AC adapter from the power outlet if you will leave the equipment unused for a long period of time.
2.
When scrapping the equipment, separate the case, circuit boards, and cables, and dispose of all components in
accordance with local waste disposal rules.
The AKG AS 8 is an 8-channel, single rack space automatic audio mixer. Using a unique mixing algorithm, the automatic
mixing action is inaudible and very simple to set up. The AS 8 offers a range of remote control options including an
RS-232 port. In addition, the AS 8 is equipped with a sophisticated compressor/leveller for dynamic range control.
Multiple AS 8s can be coupled together for applications that call for more than eight microphone channels.
The AS 8 TC is identical to the AS 8 and provides separate HF and LF controls on each channel.
For more details refer to the AS 8 / AS 8 TC Owner's Manual.
1 x AS 8 or AS 8 TC
1 x AC adapter
1 x CD-ROM with "LecNet for AKG" software
1 x RS-232 cable
1 x LecNet expansion cable
1.
Install the unit in your 19” rack.
2.
If you use only one unit, set the MASTER/SLAVE switch to "MASTER".
If you need more than eight microphone channels, you can
couple several AS 8s /AS 8 TCs together.
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 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.
1.
Connect your microphones and other audio sources to the CH 1 IN to CH 8 IN audio input terminals. All inputs are
balanced. To connect unbalanced audio sources, connect the signal lead to the "+" terminal and the shield to both
the "-" and ground terminals.
2.
If you use condenser microphones, check what supply voltage or what type of power supply they require.
If your condenser microphones will operate on +15 V phantom power, set the rear panel dip switch no. 2 for the
appropriate channel(s) to ON to switch phantom power for each condenser microphone on.
3.
Connect the MAIN OUT terminals to the amplifier input. The output is balanced. To connect to an unbalanced inputs,
connect the hot wire of the cable to the "+" terminal and the shield to ground. Leave the "-" terminal floating!
