Palmer PGA-04 ADIG-LB ADVANCED DIRECT INJECTION FOR GUITAR ADIG-LB, Advanced Direct Injection for Guitar-Load Box, is our registered trademark adam hall Copyrighted & Manufactured by: Palmer, a Division of Adam Hall GmBH Rudolf Diesel-Strasse 5, D61267 Neu-Anspach, Germany Tel.: +49 (0) 6081 94190 Fax: +49 (0) 6081 43280 Email: [email protected] CONCEPT The PGA-04 ADIG-LB is the result of our efforts to further develop our legendary speaker simulator PDI03, which has proven itself both live and in the recording studios worldwide and is being used by artists such as Keith Richards/Rolling Stones, Eric Lifeson/Rush, Warren Cucurullo/Duran Duran, Eddie Van Halen/Van Halen and Def Leppard, just to name a few. The PGA-04 ADIG-LB (Advanced Direct Injection for Guitar-Load Box, our registered trademark) offers the guitar player, sound engineer and producer, a new world of sonic possibilities far beyond the restrictions of the usual speaker/microphone setup. Built in one rack space, the PGA-04 is a monopassive speaker simulator with an internal 8ohm load-box capable of handling 120 watts of continuous power with LED’s metering the input power. The unique and variable filter circuit with volume controls will help you to shape your tone and mix both filtered and unfiltered signals to your own sound. The unit includes one balanced XLR and two unbalanced 1/4in. outputs and a speaker thru jack, giving you the option of using a speaker instead of the internal load circuit. From the studio/touring professional to the beginner needing to practice silently through your amplifier, the PGA-04 offers you a wide range of sounds and interface options right at your fingertips, giving you a great alternative to conventional micing without the disadvantages of signal bleed, loud room/stage level or bad room acoustics. Note: The PGA-04 is a totally passive unit, no batteries or external power is needed. It only accepts speaker level input and must be patched at the speaker output of your amplifier. Since the internal load-box converts the amplifier’s output power to heat, the unit must be properly mounted in your rack so the vents are not covered and the heat can dissipate. CONNECTIONS Connecting your amplifier to the PGA-04: Connect your amplifier speaker output to the Speaker Input jack of the PGA-04 by using a good quality speaker cable, 0.75mm/18 gauge minimum. If your amplifier has a speaker impedance selector switch, set it for 8ohm or use the appropriate output jack, marked 8ohm. If you want to use your speaker cabinet instead of the internal load, plug the cabinet into the speaker thru-jack. In this application the internal load is bypassed and the LED meter circuit is bypassed. Since the internal 8ohm load is bypassed, you simply need to match the impedance of the amp to the speakers, 4, 8 or 16 ohm. The internal load can handle 120 watts, but when using a speaker cabinet, you may use an amplifier up to 200 watts. Page 2 PALMER PGA-04 Owners Manual Connecting your PGA-04 to your mixer or effects chain: The PGA-04 has two unbalanced outputs (1/4in at 10Kohm) connected in parallel and one balanced (XLR pin 2 hot at 600ohm) output both having ground lifts. You may use any and all outputs at the same time. Simply connect your unit to your effects chain or directly to the snake/console or both using good quality shielded cable. If you experience a ground hum, use the ground lifts for the corresponding output to reduce or eliminate the hum. Please remember that the load-box converts the amp’s power into heat so, the ADIG-LB should be installed into a 19” rack giving the unit sufficient ventilation. The front LEDs show how much power is being sent to the load box. The last red LED should never under any circumstances constantly be lit. If it is you are in danger of damaging your unit. When using an external speaker, the load-box is bypassed and the LEDs are not in the circuit. SWITCHES AND CONTROLS Once you have your amp patched into the PGA-04 with a good quality speaker cable, turn the PGA04 volume controls (FILTER and FULL RANGE) off. Then adjust your amp’s volume by playing a chord and checking the LED display. With a 50 watt amp the first 2 or 3 LEDs should light up. And with a 100 watt amp the first 3 or 4 LEDs may light up. The LED function depends on how loud you are playing your amp. The 5th LED may blip if you are really playing loudly. Now adjust the output of your PGA-04 using the FILTER VOLUME and/or FULL RANGE VOLUME controls. Note: Since it is the speaker simulated signal, you want to start with the FILTER VOLUME control. Leave the FULLRANGE VOLUME off in the beginning-- it is an unfiltered signal. Be careful not to use too much FULLRANGE VOLUME, as it can get too bright, very quickly. If you want to use more of your amp’s natural overdrive, increase the volume of the amplifier and turn down the output of the PGA-04. VOICING Anyone who’s compared various speakers and cabinets can tell you how much they influence a guitar’s sound. The microphone type and it’s placement will also play a great role. The PGA-04 offers you the same flexibility with it’s comprehensive tone controls. The filter channel has a separate LOW (bass/cabinet) and HIGH (treble/speaker) control for shaping your tone. Of course we refrain from naming any brand names here, but the experienced musician will be familiar with the BRITISH/AMERICAN categories used to describe speaker character. The HIGH (treble) control lets you adjust your sound from soft MELLOW to aggressive BRIGHT. The LOW control will simulate cabinet type. The FLAT position stands for the somewhat thin sound of an open-back 2 x 10 type cabinet. The other extreme, DEEP, gives you the punch of a 4 x 12 stack. The wide range in between will satisfy any taste. The COLOUR switch determines the actual loudspeaker character. BROWN delivers a dark, slightly nasal basic quality, whereas LITE gives you a more open sound. The effect of the COLOUR switch is also dependent on the position of the HIGH control. Those who prefer really aggressive, distorted sounds should also mix in some of the FULL RANGE VOLUME remembering to use the HI-CUT switch, otherwise you’ll end up with that infamous paper-shredder sound. When playing clean, however, it may be desirable to add some of the FULL RANGE signal without using the HI-CUT. The result will be a quasi-acoustic sound. Since we’ve gathered from sound engineers that they have used the PDI-03 for instruments other than guitar, we believe the PGA-04’s versatility will open up a whole new range of possibilities for the creative sound engineer. That is why we refrain from giving any examples of how to recreate this or that sound - every guitar/amp combination has it’s own unique sound, and the goal of any self respecting musician or sound engineer should be to create unique sounds! Page 3 PALMER PGA-04 Owners Manual ATTENTION The internal load box uses tungsten lamps. These lamps will light up during constant high power operation. You will see light through the upper and lower ventilation slits, and possibly the other openings as well. Don’t panic, your machine isn’t about to burn up. However, you should ensure proper air circulation so that heat can dissipate. Furthermore, we’d like to remind you that amplifier output tubes can wear out sooner, the more they have to deliver high power (the louder you run them). Should you be running your amp at full levels to achieve the sound you want, anticipate having to change tubes accordingly.
