Drawmer TS1 Stereo Vacuum Tube Compressor with Instrument and Mic Pr-Amp - Manual (Page 4)

Tube Station 1 OPERATORS’ MANUAL 2
INTRODUCTION
The Tube Station 1 is a high quality Stereo Vacuum Tube Compressor with Instrument
& Mic Pre. It has an optional Digital Output module which enables SPDIF and AES/EBU
to be output from the unit. The Tube Station 1 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 TS1, 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 for
Mic. Line is at +4dBu via a Balanced jack, 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 the input and output XLR’s. 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 TS1 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 TS1 to the
patchbay. If such measures are necessary, balanced operation is
recommended.
