The Extron MLS 608 D Series are eight input, multi-format AV switchers with ProDSP™ audio
and are able to integrate analog and digital sources. There are three models:
• MLS 608 D (with variable preamp output - no amplier)
• MLS 608 D MA (with 40 watt 70 volt mono power amplier)
• MLS 608 D SA (with 2 x 20 watt stereo power amplier)
This guide allows you to easily and quickly setup and configure your MLS 608 D using step by step instructions. It covers performing
basic operations using the front panel controls and selected Simple Instruction Set (SIS™) commands.
It also gives connection information for the MTP HDMI U R twisted pair receiver, which is supplied with the MLS 608 D Series unit.
See rear cover for a diagram of a typical MLS 608 D application, showing the MLS 608 D SA model.
NOTE:For full installation, configuration, and operation details for all MLS 608 D models, see the MLS 608 D Series User Guide,
and for complete details on the MTP HDMI U R, see the MTP HDMI U R User Guide, both available at www.extron.com.
Rear Panel Features — MLS 608 D and MTP HDMI U R
NOTE: The MLS 608 D SA, as shown below, is representative of the MLS 608 D Series. It has the maximum number and type of
connectors and features of the three models. The MLS 608 D model lacks the power amplifier output.

Twisted Pair (TP) Cable Transmission Distance
CAUTION: Do not connect the MTP cable to any LAN port, telecommunications network, or digital video output port. Likewise,
do not connect a LAN cable to any MTP or digital video output port.
There are different maximum distances for analog and digital signals.
Analog signals —
The maximum distance is determined by the frequency and resolution of the signal that is input to the MLS 608 D. The table below
specifies the recommended maximum transmission distances using Extron Enhanced Skew-Free™ A/V UTP cable or UTP CAT 5, 5e, or 6
cable, terminated with RJ-45 connectors.
NOTE: The transmission distance varies greatly depending on the signal resolution and on the type of cable, graphics card, and
display used in the system.
Maximum Transmission Distances for Analog Signals at 60 Hz for MLS 608 D
For any transmission distances beyond 350 feet (100 m), turn on the pre-peak function on the transmitting device (MTP transmitter).

Digital signals —
NOTES:• The transmission distance varies greatly depending on the signal resolution and on the type of cable, graphic
card, and display used in the system.
• DO NOT use Extron UTP23SF-4 Enhanced Skew-Free A/V cable to link the switcher digital output port and the
MTP/HDMI U R receiver. Use of this cable will cause problems with the digital signal input side of the receiver.
• For resolutions of 1600x1200, 1920x1200, and 1080p, Extron strongly recommends STP201 cable, or equivalent.
STP201 cable consists of four individually shielded copper pairs and an overall braided shield that help reduce
crosstalk and extend these resolutions up to 150 feet (45 m).
• It is important to ensure the cable from output 1 on the switcher (see page 1, h ) is connected to input 1 on the
receiver (see page 1,
Likewise, output 2 on the switcher must be connected to input 2 on the receiver.

PEAKINGLEVELDIGITAL SIGNAL
Image sharpness is adjusted with the front panel Peaking adjustment knob.
This applies only to the analog side of the device. Increased peaking compensates for mid- and high-frequency detail loss.
Minimum setting (full counterclockwise) is zero peaking. Image brightness is adjusted using the Level adjustment knob.
NOTE: To avoid possible video loss due to errors in the video format detection, the user should always start with minimal level
and peaking, then increase values as required.
Adjusting level and peaking between the MLS 608 D and the receiver
1. Connect an oscilloscope (preferred) or a monitor (acceptable) to the RGB output of the MTP/HDMI U R receiver.
2. If using an oscilloscope, apply a white field test pattern to inputs 1, 2, or 3 on the MLS 608 D. The Extron VTG 300 or VTG 400 is
recommended to provide the test pattern.
3. If using a monitor, apply a grayscale or color bars test pattern to the input.
NOTE: The signal applied should be an RGB signal.
4. Observe the oscilloscope (or monitor) while you adjust the front panel input level and peaking controls to compensate for
signal loss between the MLS 608 D and the MTP/HDMI U R.
Setting level and peaking via software if using Input 4 on the MLS 608
Follow the steps 1 to 3 as given in “Adjusting level and peaking...” above. Then:
1. Start the DSP Configurator software program and connect to your device. See page 7 for software installation details.
2. Click View > Video I/O (or press <F4>); this changes
the window to the MLS workspace view. Double click
on the MTP on the input 4 (left) side of the workspace
view. The Input MTP Settings dialog box appears (see
image at right).
3. Observe the oscilloscope (or monitor) and adjust the
level using the slider. Adjust the peaking by using the
up and down arrows. Disconnect test equipment when
finished.
MTP/HDMI U R
Setting the Skew on the MLS 608 D
Adjusting output skew between the
MLS 608 D and the receiver:
1. Connect an oscilloscope (preferred) or a monitor
(acceptable) to the RGB output on the MTP/HDMI U R.
2. Apply a crosshatch test pattern to input 1, 2, or 3
on the MLS 608 D.
3. Use the test equipment or examine the video image
with a critical eye to determine which video signal
(red, green, or blue) is most shifted to the left.
4. Within the DSP Configurator program, click View > Video I/O (or press <F4>) to access the MLS workspace view. Double-click
MTP on the output (right) side of the workspace view. The Output MTP Settings dialog box appears (see image above).
5. Adjust the furthest left video signal by using the up and down arrows for the relevant signal color, and repeat as needed until
all three colors are aligned correctly.
Adjusting input skew if using Input 4
Follow the steps 1 to 3 as given in “Output skew”, above. Then:
1. Within the DSP Configurator program, click View > Video I/O (or press <F4>) to access the MLS workspace view.
Double-click MTP on the output (right) side of the workspace view. The Output MTP Settings dialog box appears.
2. Adjust the furthest left video signal by using the up and down arrows for the relevant signal color, and repeat as needed until
all three colors are aligned correctly.
Selecting the MLS 608 D Output Prepeaking
1. Click View > Video I/O (or press <F4>); this changes the window to the MLS workspace view. Double-click on the MTP on

Reset Mode 1, Use factory firmware — To reset temporarily to the factory default firmware, press and hold the reset
button in while applying power to the unit.
NOTES:• After a Mode 1 reset, update the rmware to the latest version. DO NOT use the factory rmware resulting
from the reset. Factory firmware must be re-uploaded if that is the version to be used.
• If you do not want to update the rmware, recycling the power reinstates the rmware version used before
the Mode 1 reset.
