Audio And Power Connections; Connecting The Transmitter To Your Audio Source; Connecting The Transmitter To Power - AKG Acoustics HEARO 787 SURROUND Mode D'emploi

The STEREO, IVA, PRO LOGIC, and LOGIC7 labels will illuminate to indicate the selected mode:
10.LEVEL: As long as audio signal is present at the transmitter input, the green LEVEL label will flicker in step
with the signal level.
Since signal levels are controlled automatically, the transmitter has no input gain knob.
11.Charging contacts: The transmitter provides charging contacts in the left-hand earphone receptacle.
When you place the headphones in the receptacles, the batteries inside the headphones will be charged
automatically.
12.CHARGE: This label indicates the charging function status:
The CHARGE label illuminates to indicate the batteries inside the headphones are being charged. Since
the charging circuitry operates independently from the rest of the transmitter circuitry, the CHARGE label
will light even if the transmitter is OFF.
The CHARGE label will remain dark when no current flows from the transmitter through the charging con-
tacts to the batteries inside the headphones (transmitter is not connected to power, no headphones rest-
ing on the transmitter, no batteries inside the headphones, batteries inserted incorrectly, contaminated
charging contacts).
13.AUDIO IN L/R: Left and right RCA audio input jacks.
14.DC 9 V: Input jack for the AC adapter.
15.O O: Alternative stereo input on a TRS mini jack.
You can connect the transmitter either to a mini or 1/4" headphone jack or LINE OUT or REC OUT RCA jacks.
1. Before connecting the transmitter to your audio source, switch the audio source OFF.
2. Plug the red RCA connector (right channel) on the supplied jack cable into the red AUDIO IN R
socket (13) and the white RCA connector (left channel) into the white AUDIO IN L socket (13) on the trans-
mitter rear panel.
3. Connect the stereo mini jack plug of the jack cable to the headphones output of your audio source.
4. If the headphones output on your equipment is a 1/4" jack, plug the supplied mini jack to 1/4" adapter jack
onto the jack cable. Connect the adapter jack to the headphone output.
1. Plug the white RCA connector (left channel) on the jack cable into the white LINE OUT L or REC OUT L
socket on your audio source and the red RCA connector (right channel) into the red LINE OUT R or REC
OUT R socket.
2. Plug the mini jack plug on the jack cable into the O O jack (15) on the transmitter rear panel.
Alternatively, you can use a standard stereo RCA cable. These cables are available at hi-fi or electronic
supply stores.
Never connect two audio sources simultaneously to the transmitter inputs. Playing back two audio
signals at the same time may cause severe distortion.
Check that the AC voltage stated on the supplied AC adapter is identical to the AC voltage available
where you will use your system. Using the AC adapter with a different AC voltage may cause damage
to the unit.
1. Connect the cable on the supplied AC adapter to the DC 9 V jack (14) on the transmitter rear panel.
2. Connect the AC adapter to a convenient AC outlet.
