INTRODUCTION

THANK YOU!...

for choosing the Manley Laboratories Tube-Direct Interface. This manual covers both mono and dual-mono (stereo)
units. Please take a few moments to read through this manual.

LOCATION & VENTILATION

The Tube-Direct Interface must be installed in a stable location with ample ventilation. It is recommended that you
allow enough clearance on the top and bottom of the unit such that a constant flow of air can flow through the ventilation
slots.

MAINS CONNECTIONS

Your Tube-Direct Interface has been factory set to the correct mains voltage for your country. The voltage setting is
marked on the rear panel. Check that this complies with your local supply.

Export units for certain markets have a moulded mains plug fitted to comply with local requirements. If your power cord
does not have the appropriate plug fitted the coloured wires should be connected to the appropriate plug terminals in
accordance with the following code.

GREEN/YELLOW EARTH terminal
BLUE NEUTRAL terminal
BROWN LIVE terminal

As the colours of the wires in the mains lead may not correspond with the coloured marking identifying the terminals in
your plug proceed as follows;

The wire which is coloured GREEN/YELLOW must be connected to the terminal in the plug which is marked by the
letter E or by the safety earth symbol or coloured GREEN or GREEN and YELLOW.

The wire which is coloured BLUE must be connected to the terminal in the plug which is marked by the letter N or
coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal in the plug which is marked by the letter L or
coloured RED.

DO NOT CONNECT/SWITCH ON THE MAINS SUPPLY UNTIL ALL OTHER CONNECTIONS HAVE
BEEN MADE.

WATER & MOISTURE

As with any electrical equipment, this unit should not be used near water or moisture.

The user should not attempt to service this unit beyond that described in the owner's manual. Refer all servicing other

CONNECTING YOUR DIRECT INTERFACE

1. Be certain that the unit is switched off.

2. Connect the supplied IEC Mains Cable to the IEC receptacle on the rear of the unit.

3. Connect a 1/4" phone jack marked 'OUT TO AMP' (on the Dual version this is
marked "Unbalanced Output") to your guitar amplifier.

4. Connect a 3 pin female XLR cable from the socket marked 'OUT TO CONSOLE' to
to your console microphone level input. This output is designed to provide a direct feed from
the Tube-Direct Interface to a micpre input. Thus you can later mix in this feed with the
guitar amp mic'ed cabinet. Do NOT supply phantom power to this output!!

5. Connect your instrument's output to the Instrument Input on the front panel. Electric
Guitar, bass, keyboards, etc.

6. Turn on the power and allow the unit several minutes to 'warm up' before opening the

gain on your amplifier.

7. Go for it!
