[. . . ] Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. In no event will PreSonus be liable for incidental, consequential or other damages resulting from the breach of any express or implied warranty, including, among other things, damage to property, damage based on inconvenience or on loss of use of the product, and, to the extent permitted by law, damages for personal injury. Some states do not allow the exclusion of limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights, which vary form state to state. [. . . ] This assures optimum performance of your condenser microphones that require phantom power. This pad provides a more manageable signal from high output devices or extremely loud sources (drums) giving greater control over the in-coming signal to avoid clipping or distortion during recording. Use the phase invert switch to combat phase cancellation with other open microphones. Eight segment LED meters for detecting peaks and fast transients of the output level. · · · · · · · 5 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 (1500, 900, 300 and 150 ohms). As the ADL 600's impedance is lowered, different filtering effects can result delivering a tailored sound for a particular application. When using the Line input, the following microphone preamplifier features are bypassed: +48V, -20dB PAD and input impedance. HP FILT: Three position rotary switch to select the frequency for the HIGH PASS FILTER (40Hz, 80Hz and 120Hz). When the FILTER switch is engaged all frequencies below the selected HP FILT setting are attenuated (dropped) by 12dB. For example, a high pass filter can help to reduce the "boominess" or "muddiness" of a vocal and improve the overall clarity. GAIN: Eight-position industrial grade rotary switch providing 35dB of gain in 5dB steps. TRIM: Variable potentiometer (+/-10dB) to offer fine trim adjustment to the final stage of the ADL 600. When an instrument is plugged into the instrument input, the microphone preamplifier is bypassed and the ADL 600 becomes an active instrument preamplifier. 6 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 cancellation between microphones. -20dB PAD: Engaging the PAD switch provides 20dB of attenuation. This is a very useful feature for reducing the level coming into the ADL 600 and thus preventing the signal from clipping or distorting. This may occur due to high output level from a microphone or other device. Padding the input serves to provide increased "headroom" for the operator while lessening the likelihood of signal overload. This can help you meter loud input sources if your VU meter is "slamming" or is pegged. POWER: Turns your ADL 600 ON/OFF. 7 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 PIN 2 PIN 3 GND High 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 was shipped.
