Tube Station 2 OPERATORS’ MANUAL

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.
