I have a recording studio. What Palmer gear will help me record directly to the console without losing tone or signal?
The PGA-04 or PDI-03 with the built-in load box is perfect for recording your tube amp head direct to the console.
The PGA-05 can be used primarily with pre-amps to enhance the tone straight to the console.
And although the PDI-09 is designed for guitar amps, you can also connect it to a pedal board (or preamp) for a great sounding DI straight to the console.
My studio does a lot of business. Is the PGA-04 and/or PGA-05 easy for a variety of guitar players to use?
Yes, your guitar players will love the Palmer gear--no matter what style they play. Easy operation!
You simply connect the PGA-04, with its built-in 8 ohm load box, instead of their speaker cabinet--record directly to your console. Or you can connect the speaker cabinet out of the PGA-04 and record direct + mic the cabinet.
The PGA-05, 2-Channel stereo cabinet simulator with no load box, is just as simple. Connect the outputs of the pre-amp or FX rack and record straight to the console with great cabinet tone.
Can I use the Palmer gear with my solid state amp?
You betcha. As long as you don't exceed the (120 watt Palmer) power limit.
I play bass guitar. Which Palmer gear would be right for me?
Although most bass amps have a direct output, you should try a PDI-09 or a PGA-04 connected between your speaker output and your cabinet. Then connect the XLR output to the console. With this setup, you will get the full tone of the preamp and the power amp section to the console.
Is the PDI-09, PGA-04 or PGA-05 an effects box?
No. An effects box has reverb, chorus, delay, etc. The PDI-09, PGA-04 and PGA-05 are guitar direct boxes, and are all designed to create an authentic speaker cabinet tone without having to mic your cabinet. No more hanging a mic through your amp handle. 'Bout time!
What's the advantage of the PDI-09 over some other guitar direct box?
The PDI-09 is very clean and transparent. It has a 3 position attenuator switch and a 3 position tone switch, making it useful for pedal boards and tube amps for direct output to a console.
Do I have to run a cabinet with my PDI-09?
Yes, the PDI-09 is a filtered DI box for guitar amps to connect between the amp and the speakers. It does not have a load circuit built into it. You can only use a PDI-09 without speakers if you connect an external load box in place of the speakers.
What's the difference between the PGA-04 and PGA-05?
The PGA-04 is a mono speaker simulator with a built-in 8 ohm load box. You can use it with or without speakers--set your tube amp head to 8 ohms.
The PGA-05 is a stereo unit designed to use with line level preamp equipment. It does not have a load box onboard. The PGA-05 has a line/speaker input switch on the back of the unit to facilitate the use of a preamp or an amp.
Can I run a speaker cabinet with my PGA-04? PGA-05?
Yes. With the PGA-04, just plug a cabinet into the 'thru' jack, then into the cabinet. The internal load box is by-passed in this mode.
With the PGA-05, you must set the line/speaker level switch on the back of the unit to speaker level, then plug a cabinet into the PGA-05.
What's the difference between the PGA-04 and PDI-09?
The PGA-04 is a mono speaker simulator with a built-in 8 ohm load box. You can use it with or without speakers when your tube amp head is set to 8 ohms.
The PDI-09 does not have a load box built in, so you need to use a cabinet or an external load box.
When would a Triline come in handy?
It's really a versatile little piece of gear. The Triline can be used to route your guitar signal to 2 different amp setups. Simultaneously or Separately. It also has a built-in direct output for your acoustic guitar's connection to the console. When used in conjunction with the E-Frog cabinet switcher, you can route your signal between 2 different amp heads connected to 1 cabinet.
I keep reading about the original PDI-03. Has it really been reissued?
Exciting News! Although the legendary PDI-03 has been out of production for quite some time, Martin Schmitz, the designer of Palmer products has heard your pleas and decided to put it back in production. As of September 2005 the original PDI-03 is available again. Martin gave us a great interview on the PDI-03. Read it here.
What's the difference between the PGA-04 and PDI-03?
The PDI-03 and the PGA-04 have the same speaker simulator filter circuit. There are two main differences: the EQ section and routing of the filtered and unfiltered signals.

The PDI-03 has two 3-position switches: one for the highs and one for the lows. On the PDI-03, the filtered and unfiltered signals are separate with dedicated volume controls and output jacks. This signal routing feature enables you to use the PDI-03 like a splitter and send a line-level output signal to separate power amps, effects racks or consoles.

The PGA-04 has rotary knobs for the highs and lows. It also has a Brown/Lite switch for the filtered section which is like a pre-set mid-range control. In the signal routing, the filtered and unfiltered signals are mixed internally by individual volume controls and sent to the same output jacks. The unfiltered signal has a 6K switch for tweaking the highs.

When I'm mounting my speaker simulator, do I need to leave a rack space for ventiliation?
The resistors in the load circuit are what gets hot, so this only applies to the PDI-03 and PGA-04. The PDI-03 is rated at 100 watts and the PGA-04 is rated at 120 watts. Both units will take up to 200 watts in short peaks. Starting at about 60 watts it is best to leave an empty rack space above the Palmer. If you are running your amp at 100 watts or more, you should probably leave a space both above and below your Palmer to help the heat dissipate.
What Warranty is offered by Palmer Products?
As of October 2007: Palmer offers the original owner a 5 years unlimited warranty against defects in materials and workmanship.
What's the difference between "Available" and "Special Order"?
We make every effort to keep in stock the gear our customers want.
"Available" means the product is in stock. Your order will be processed promptly. You will be provided with the order confirmation and tracking information when it is shipped. We will notify you of any unexpected delay to your order.
"Special Order" items will need to be prepaid and could take 4-6 weeks to ship. The gear is made special for you at the Palmer factory in Germany, shipped to us, and we ship to you. The cycle usually takes about 4-6 weeks. You will be notified when your order is shipped and tracking information will be provided at that time.
What does ETA mean?
When an item is marked "ETA" (Estimated Time of Arrival) it is temporarily out of stock due to high demand. An order has already been placed with Palmer. The date quoted is when we expect to receive the gear. As soon as we get it in, you will be notified when your order is shipped and tracking information will be provided to you.
What's my order status?
You will be e-mailed a confirmation when your order is received, and shipped. To see where your order is in the system, you can go to UPS.com and enter your tracking number.
How do Special Orders work?
A "Special Order" item will need to be prepaid and could take 4-6 weeks to ship. The gear is made special for you at the Palmer factory in Germany, shipped to us, and we ship to you. The cycle usually takes about 4-6 weeks. You will be notified when your order is shipped and tracking information will be provided at that time.
