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.
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.
FRONT PANEL LIFT CONSOLE BOOST INSTRUMENT UNITY INPUT GROUND A B POWER ON BASS FULL BASS MEDIUM GUITAR / SYNTH GUITAR MEDIUM GUITAR BRIGHT C OFF D E F A GROUND LIFT Disconnects chassis earth from Pin 1 on the XLR console output. If at first it hums - switch this. In general, if there is an amp involved then the best place to start is in the "LIFT" position. B GAIN SELECT Selects low or high gain feeding the XLR "OUT TO CONSOLE". Both labels "CONSOLE BOOST" and "UNITY" need explanation.
REAR PANEL A B C D A IEC MAINS SOCKET Standard IEC mains socket accepts supplied power cord. B FUSE HOLDERS Replace with 1A SLO-BLO fuse only. C OUTPUT (XLR) Transformer Balanced: Pin 1 - Ground (Switchable) Pin2 - Positive going phase (+) Pin3 - negative going phase (-). Connect directly to console mic preamp or outboard mic preamp. This is a low-Z mic level send and not line level. Phantom power should be disabled on this channel but the 48 volts will not harm the DI but can cause big noises.
OPERATIONAL NOTES POWER It is not recommended that you leave your Tube-Direct Interface permanently switched on. This only wastes electricity and tube life. Tubes filaments are more fragile when hot. Let it cool. TUBE LIFE As with all tubes, their quality degrades with age. This is due to cathode emission, a natural process found in all tubes. We recommend that you have your unit checked every 4-5 years, depending on usage. Increased microphony can indicate the need to re-tube.
CONNECTIONS DI's can be patched into several places in the chain. The most common and most useful is between the instrument and amplifier - The amp is optional. An interesting variation is after the musicians pedals and effects. Another good place is the insert loop of some amps. The results vary from great to not good. There is no standard in amps as to where the loop is and what it does. It is worth a try.
3) Return the signal to a mic pre. Manley Tube mic pre is prefered of course. 4) EQ - Roll off the top end somewhere between 6kHz and 10kHz, boost 40 - 80 Hz and maybe some mid frequencies. This is to simulate the speaker and cabinet. 5) Effects. mix in some delay or short reverb to get the "room" sound. This big patch would be Tape into (optional EQ into) Compressor (just for gain) into DI into mic pre into good EQ and then mix in some effects.
