Tone generators BLITS ATG202 ATG332
The BLITS 5.1 tone generator was designed in conjunction with Martin
Black and Keith Lane at BskyB.
Martin and Keith devised the BLITS tone sequence primarily for use with
their HDTV broadcasts with associated 5.1 surround sound.
The BLITS is currently used on all Sky Sports surround sound outside broadcasts.
Provision is made for stereo line identification, channel phase and identification
of the six 5.1 audio channels, L,R,C,LFE,Ls and Rs. These channel identification
frequencies correspond to notes A5,A5,E6,E2,E5,E5 respectively.
The tone generator may be switched between 5.1 and stereo oscillator sequences
and individual 5.1 sequences may be 'looped'. The unit also includes a
discreet EBU tone source and may be controlled by external GPIs. An
input is provided for AES sync reference.
All audio outputs are mirrored by illuminated leds on the front panel.
The Blits supplies both analogue and AES/EBU outputs. Digital outputs
may be specified with either 75 ohm unbalanced outputs on BNCs or 110
ohm balanced outputs on XLRs. All analogue outputs are on XLRs and electronically
balanced.
The ATG202 is a low distortion high stability 1RU rack mount stereo
tone generator.
The tone generator will supply either EBU, Glits or steady tone
at 1kHz. Front panel level adjust with output status indicators.
The ATG332 generates three tone standards,
Glits, EBU and dual language (1kHz/400Hz) simultaneously.
Each tone type has two individually buffered stereo outputs and every
output has front panel level adjustment.
XLR outputs.
1RU rackmount.
Low distortion (0.03%) high stability outputs.
