Connecting the goose neck microphone:
How do I connect the Sirius?
1.) Connecting the Sirius to a stereo system:
First plug the enclosed goose neck microphone into the XLR input which is located at the top right of
the front panel of the Sirius.
On the back of the Sirius you will find two 6,3mm (1/4") jack sockets, the stereo output pair. These
sockets are marked audio-left and audio-right. The amplifier, stereo system or mixing desk will be
connected to these outputs. You will need a mixing desk if you wish to run other instruments apart
from the Sirius through the amplifier or stereo system. The 5-pin din sockets which you will also find
on the rear panel are for the transmission of MIDI information and do not output any audio signal
(sound). A more detailed explanation of the MIDI-connections can be found in the chapter called:
"The Sirius and MIDI".
The following is a detailed description of how to connect the Sirius to the three types of audio equip-
ment we have already mentioned. A detailed connection plan can also be found on the page after
next (Page 11):
First turn off your stereo system and the Sirius. You will need the two enclosed jack-jack cables and
the two jack-phono(RCA) adapters to make this connection. Not all of the auxiliary inputs at the rear
of your stereo amplifier are suitable for connecting the Sirius. Choose one of the following possibili-
ties:
1.) AUX or Auxiliary
2.) LINE
3.) CD
4.) DAT
5.) TAPE IN or TAPE PLAY
Totally unsuitable for the connection of the Sirius is the PHONO input of your stereo amplifier, as
this input has a pre-amp and is constructed for your record player. This input would distort the sound
of the Sirius.
Put the two jack cables in the AUDIO-LEFT/RIGHT socket of the Sirius. Connect the jack-
phono(RCA) adapters to the other end of the cables. Now you can connect the cables to the stereo
amplifier.
Turn the volume dial of the stereo and the MASTER-VOLUME dial of your Sirius to minimum. Now
first switch on the Sirius and then the stereo system. Turn the input selector on your stereo amplifier
to the input you chose when connecting the Sirius. Now turn the MASTER VOLUME dial of the
Sirius to Maximum. Press the START-Key of the Sirius (located in the SEQUENCER section on the
front panel) to start a sequence. Carefully turn up the volume of your stereo system to the desired
level. In order to avoid damage to your speakers due to the deep bass frequencies the Sirius is able
to create you might have to lower the bass level on your stereo amplifier.
