1.  XLR Inputs

 - Front panel female XLR jacks allow easy 

connection  of  individual  signals.  Rugged,  glass-rein-

forced nylon construction for reliable connections.

2.  Front Panel Lift Switch

 - Disconnects the ground path 

at the auxiliary and isolated outputs. Using the front pan-

el ground lift can eliminate ground loop noise between 

equipment connected to the LX8 outputs.

3.  Easy ID Label Zones 

- For dry-erase markers or wax 

pencil identification. Handy when using several LX8 at 

a time.

4.  Military Grade PCB

  -  The  dual  layer  circuit  board  is 

manufactured  with  plated  through  holes  and  secured 

with 8 standoffs.

5.  Transformers

 - Each transformer is mounted directly on 

the PCB in close proximity to the input for the shortest 

possible signal path.

6.  Heavy-duty Switches

 - Front panel switches are metal 

encased and rated at 20,000 operations.

7.  Internal Chassis Ground Lift

  -  Input  connectors  are 

100% isolated from the chassis, but an internal switch 

is provided to connect signal ground (pin-1) to the chas-

sis without modifying the LX8. By default, this switch is 

factory set to “lifted” allowing the chassis to “float” un-

grounded and should remain this way unless a specific 

grounding scheme requires the signal ground to be tied 

to the chassis.

8.  14-Gauge Chassis

  -  Made  extra  tough  with  heavy 

gauge  steel  and  welded  corners  to  provide  excellent 

shielding and durability. Finished in baked enamel.

9.  Isolated Output

  -  This  output  is  transformer  isolated 

to block noise caused by ground loops and is wired in 

parallel to DB-25 and Euroblocks terminals.

10.  Auxiliary Output

 - This is a direct output  wired in par-

allel with the DIRECT output. The signal grounds may 

be disconnected using the front panel LIFT switch. This 

output is wired parallel to the DB-25 and Euroblocks ter-

minals.

11.  DB-25 Pin-out Diagram

 - The pin-out for the female DB-

25 connector is diagramed on the rear panel. All DB-25 

connectors follow the Tascam standard for eight channel 

analog signal interface.

12.  Direct Output

 - This output passes signal through the 

LX8 and is wired parallel to the DB-25 and Euroblocks 

terminals.

13.  Euroblock Sockets 

- These panel sockets receive 12-

pin  Euroblock  screw  terminals.  Each  Euroblock  con-

nects four channels with bare wire termination and fa-

cilitate custom options like interfacing a connector panel 

or multi-pin disconnect. Euroblocks screw terminals are 

optional and must be ordered separately. (Radial order 

# R800 8050)

14.  Rear Inputs

 - The rear panel DB-25 and Euroblock in-

puts connect all eight channels and are wired parallel to 

the front XLR connectors. 

15.  Chassis Ground - 

Ground screw connection point used 

in conjunction with the internal chassis lift switch to bond 

the LX8 to earth.
