1. Purpose of use
AV-200T is a digital modulator designed for a processing two audio and two video signals into one
COFDM (DVB-T) multiplex.
2. Installation
The connections and indications are shown in Fig 1.

2. Channel number ( CCIR)
3.Control switch to program channel in ON position. The switch must be set to OFF (DOWN) position when
programming is ready1.
4. IR detector
5. VIDEO/AUDIO outputs for monitoring
6. Audio IN (right)
7. Audio IN (left)
8. RGB IN (blue) or YPbPr (Pb)
9. RGB IN (green) or YPbPr (Y)
10. RGB IN (red) or YPbPr (Pr)
11. Video IN and SCART SYNCHORIZING IN
12. USB port for software update
13. S-Video IN
14. When signal led is orange, the unit is initialized. When signal led is green, the outgoing stream is ready. Red led means
overfull stream.
AV-200T is installed to 19” rack. Do not cover the air passage holes.
Signals from AUDIO/VIDEO source are fed to Audio/Video connectors (RCA female) or S VIDEO IN.
VIDEO/AUDIO connectors (5.) are for monitoring the unit while programming.
NOTE! If video input is not connect, there are white stripes in video output due to the missing sync
pulse.

3.2 First time set-up
When using the unit for the first time, you must first connect video and audio source to audio/video inputs
and then connect video output to monitor. After this you can continue set-up using on-screen menus.
To control the unit first slide front panel switch to ON position. When programming is ready, the front panel
switch must be slide to OFF position. This will prevent accidental changes to be made while controlling
other units.
3.3 Set-up
To start set-up, press Menu key. Main Menu will be displayed.
Select “ Modulator Configuration”.
In Modulator menu can be selected:
- Output channel from S2 to E69
- DVB-T Constellation (QAM 64 is recommended)
- DVB-T FEC 1/2, 2/3, 3/4, 5/6 or 7/8 (3/4 is recommended)
- DVB-T Bandwidth 7 MHz or 8 MHz
- Output Level attenuator 0...20 dB (20 is maximum output level)
- Fine Tune of output frequency with 0,5 MHz steps

Select “Encoder Configuration”
Following options can be selected for both channels:
- Input video signal Composite, S-video, RGB (synchorizing on GREEN), SCART RGB
(synchorizing on VIDEO), YPbPr (synchorizing on GREEN), SCART YpbPr (Synchorizing on
VIDEO)
- Hor. Resolution DI (full resolution 720*576), HD1 (half resolution 360*576) CIF (quarter resolution
360*288)
- GOP Size 6,12,15,24 or 30 (maximum frames per GOP: 18 (NTSC) / 15 (PAL)
- GOP Structure I (each GOP consist only of I-frames), IP (the encoder uses one I-frame and then only
P-frames inside a GOP), IBP (the encoder uses an I-frame at the beginning of the GOP and encodes
the rest in B- and P-frames) or IBBP (the encoder uses an I-frame at the beginning of each GOP and
encodes the rest in B- and P-frames)
- Const. Bitrate 1,5 Mbit/s, 2 Mbit/s, 4,5 Mbit/s or 6 Mbit/s
- Audio Sample Freq. 32,0 kHz, 44,1 kHz or 48 kHz
- Audio Bitrate 64 kbit/s, 128 kbit/s or 256 kbit/s
- Audio ES Mode Mono, Dual, Stereo
NOTE! The change of parameters are saved with “EXIT”. If “MENU” is selected, the change of parameters
is not saved.
