5. Preparing Procedures

5-1 SIEM-2T

1. Set the rubber pad

Four self-adhesive rubber pads are provided to ensure the

stability. They are to be placed on the bottom of the

transmitter.

2. Power Suppty

2. DR-900(Optional)

2. Connect the audio source, such as a mixer.

Connect the mixer output to the XLR /ɑ6.3mm combo

input in the Front panel of SIEM-2T with the AF input

cable.

NOTE: Two balanced XLR /ɑ6.3mm combo inputs are

provided. You may use either one or both for a stereo source.

Also, two balancedɑ6.3mm loop out connectors are provided

for multiple systems application.
