2 CONTROLS & CONNECTIONS 2.1 FRONT PANEL LAYOUT The front panel of the ADL 600 is laid out so that if you split the front panel down the middle the controls and metering for channel 1 are on the left hand side and the controls and metering for channel 2 are on the right hand side. The following is a description of the controls for each channel: INPUT: Selects the input source (Instrument, Line, or Microphone) The microphone input has four different input impedance values to select from

CONTROLS & CONNECTIONS +48V: The 48 volts supplied by way of the XLR connector, provides power for condenser mics and any other devices requiring continuous phantom power through the XLR input. This power is supplied at a constant level to prevent any degradation of audio quality. XLR connector wiring for Phantom Power Pin 1= GND Pin 2= +48V Pin3= +48V POL INV: Reverses the polarity of the signal. Use the phase invert when recording with more than one open microphone to combat phase c

CONTROLS & CONNECTIONS 2.2 BACK PANEL LAYOUT Connectors All Input and Output connectors are transformer balanced. XLR with the following wiring standard: XLR PIN 1 GND PIN 2 High (+) PIN 3 Low (-) NOTE: The LINE INPUT does not pass signal unless the INPUT selector switch is set to LINE on the front panel. 2.3 POWER AND GROUND AC POWER: Your ADL 600 accepts a standard IEC cord. Note: The input power voltage is set at the factory to correspond with the country in which it w

3 OPERATION 3.1 INPUT SOURCES The ADL 600 can be used with a variety of input sources: microphones, instruments and line level devices. 3.2 MICROPHONES The ADL 600 works great with all types of microphones including dynamic, ribbon and condenser microphones. Dynamic microphones and ribbon microphones are generally lower output devices and require no external power source. Condenser microphones are generally more sensitive than dynamic and ribbon microphones and typically require externa

OPERATION 3.6 APPLICATIONS The following are a few two-channel recording applications for you to get you started in using your ADL 600. These are by no means the only way to record these instruments. Microphone selection and placement is an art form. If you would like more information, visit your library or local bookstore as there have been many books published on recording techniques. 1. Piano – Place one microphone above the high strings and one microphone above the low strings. Expe

OPERATION 2. Electric Guitar – Place a dynamic or ribbon microphone an inch or two away from the speaker of the guitar amplifier. Experiment with exact location. If you are recording an amp with multiple speakers experiment with each one to see if one sounds better than the others. Place a condenser microphone approximately six feet away pointed at the amp. Experiment with distance. Also experiment with inverting the phase of the room microphone to check for phase cancellation (select

OPERATION 3. Acoustic Guitar – Place a small diaphragm condenser th microphone pointed at the 12 fret approximately eight inches away. Place a large diaphragm condenser microphone pointed at the bridge of the guitar approximately twelve inches from the guitar. Experiment with distances and microphone placement. Another popular method is using an XY microphone placement with two small diaphragm condenser microphones. (see drum overheads photo on page xxx). 14

OPERATION 4. Bass Guitar (Direct and Speaker) Plug electric bass guitar into a passive direct box. Connect instrument output from the passive direct box to a bass amplifier. Place a dynamic microphone an inch or two away from the speaker and connect microphone to ADL 600 microphone input. Connect the line output from the passive direct box to LINE INPUT on the ADL 600. Record separate channels. During mixing you can blend the direct and amplifier signal to taste. 15

OPERATION 6. Snare Drum – (top and bottom) Place dynamic microphone pointed at the center of the snare making sure drummer will not hit it. Place small diaphragm condenser microphone under the drum pointed at the snares. Experiment with microphone placement of both microphones. Also experiment with inverting the phase of the bottom microphone. 17
