Tube Station 2 OPERATORS’ MANUAL2
INTRODUCTION
The Tube Station 2 is a high quality Dual Channel Vacuum Tube Compressor. It has
an optional Digital Output module which enables SPDIF to be output from the unit.
The Tube Station 2 is suitable for both live sound and studio applications. All buttons
have status LEDs.
INSTALLATION
The TS1 is designed for standard 19" rack mounting and occupies 1U of rack space.
Because the tube circuitry generates more heat than an equivalent solid-state design,
it is recommended that 1u of space is left above and below the unit, where space is
available, to allow the heat to dissipate. In addition the rack should be fan cooled,
with air blowing onto the TS2, this will extend the life and reliability of the units.
Avoid mounting the unit directly above power amplifiers or power supplies that
radiate significant amounts of heat and always connect the mains earth to the unit.
AUDIO CONNECTIONS
Input and Output connections are provided for use at +4dBu via balanced XLRs. If
unbalanced operation at +4dBu is required, simply connect the unused terminal to
Ground inside the balanced jack socket. This applies to both inputs and outputs. The
wiring convention for XLR being: pin 1 Ground, pin 2 Hot and pin 3 Cold. For use with
unbalanced systems, the Cold pin 3 must be grounded at both input and output XLRs.
For jack operation refer to diagram.
Interference: If the unit is to be used where it maybe exposed to high levels of
disturbance such as found close to a TV or radio transmitter, we
suggest that the unit be operated using the XLR connectors. The
screens of the signal cables should be connected to the chassis
connection on the XLR connector as opposed to connecting to
pin1. The TS2 fully conforms to the EMC standards.
Ground Loops: If ground loop problems are encountered, never disconnect the
mains earth, but try disconnecting the signal screen on one end
of each of the cables connecting the outputs of the TS2 to the
patchbay. If such measures are necessary, balanced operation
is recommended.

POWER CONNECTION
If the unit is required to operate at a mains input voltage which is different to that as
supplied:
The following procedure must be carried out by a qualified technical engineer.
1: Disconnect the unit from the mains.
2: Remove the twelve screws that retain the top cover.
Accessing the internal power switch and fuse
3. Set the voltage rating and replace the fuse.
Mains Voltage 230V Fuse Value 160mA.
Mains Voltage 115V Fuse Value 315mA.
4. Replace the cover.
