LASSEN 88DS 8x8
LASSEN SDI™ 8 SERIES ROUTING SWITCHERS
LASSEN SDI 88 SERIES SERIES
SDI VIDEO WITH STEREO AUDIO.
DESCRIPTION
The Lassen 8 series are high performance routing switchers for SDI (SMPTE 259) and HD -
SDI (SMPTE 292) video signals. These units come in a compact 2U (3.5” ) frame and can
be ordered with or without digital audio. They can route any or all inputs to any or all
outputs. HD - SDI models can input SDI and HD - SDI simultaneously, but there is no
conversion between formats.
LASSEN XL ANALOG (COMPOSITE) VIDEO FEATURES -
High Bandwidth - 300MHz ( - 3dB) fully loaded.
Very Low Crosstalk - 80dB @ 1MHz, - 47dB @100MHz.
Qwik Adjust Knob™ Rotary Control interface - This user intuitive knob along with the 80 character LCD display provides quick and convenient setup,
adjustment and signal switching.
Video Mute Capability -
Genlock Input - Looping internal sync input for vertical interval switching.
Output Disconnect Feature -
LASSEN SDI VIDEO FEATURES -
Maximum Data Rates - 360Mbits/sec.
Standards - SMPTE 310, SMPTE 259, DVB - ASI.

Maximum Data Rates - 1.485Gbits/sec.
Standards - SMPTE 310, SMPTE 259, SMPTE 292, DVB - ASI.
Jitter - < 0.2UI.
ANALOG AUDIO FEATURES. -
Audio Type - Balanced or un - balanced on terminal blocks.
Input (Level) Adjustment Capability ( - 10dB to +15dB) - Each input via RS - 232, front panel, and G.R.I.P software.
Output (Volume) Adjustment Capability (Mute, - 59.5dB to +15dB) - Each input via RS - 232, front panel, and G.R.I.P software.
No Zipper Effect - Lassen routing switchers employ zero crossover chip technology which eliminates the annoying “zipper sound effect”associated with
digital volume controls.

Crosstalk - 80dB @ 1kHz & 70dB @ 20kHz.
S/N (20 - 20kHz) - 90dB.
DIGITAL AUDIO FEATURES -
Standards - Balanced AES/EBU.
Jitter - +/ - 20ns.
OTHER FEATURES -
Firmware Updates - Downloadable.
Control - Local front panel control with 80 character LCD readout.
RS - 232/422 plus RS - 485 for optional control panels.
IP (Ethernet) control.
G.R.I.P: Windows ® - based routing switcher setup/diagnostic software.
Redundant Power Supplies - Optional on 32x16 & 32x32 models.
Approvals - UL & CE.
Control Panels (Optional) - Programmable, Single Bus and XY.
