POWER SUPPLY

Although it is light and compact, the PT-3D furnishes two completely independent isolated output terminals (9 VDC/500 mA) and six low-noise standard output terminals (9 VDC/100 mA) and can power up to eight lines.
The PT-3D’s isolated output terminals can supply current higher than 1 A momentarily required by some digital effects units on boot. After booting of the units, the PT-3D can stably continue to supply required amperage up to 500 mA.
This makes the PT-3D, which is designed to supply 9 VDC, applicable to effects units requiring high capacity current (such as DigiTech® WHAMMY DT™/WHAMMY 5™, Eventide® TIME FACTOR/MOD FACTOR/PITCH FACTOR /SPACE/H9, LINE6® DL4™/MM4™/FM4™, Strymon® TIMELINE/MOBIUS).

FEATURE

  • Like other PT series products, rigidity and lightness are attained by making the housing of Japanese-made aluminum alloy used in aircraft parts.
  • Two completely independent isolated output terminals (9 VDC/500 mA) and six low-noise standard output terminals (9 VDC/100 mA) can power up to eight lines.
  • Each 9VDC output terminal is stabilized and powers the effects unit via the separate noise filter and short-circuit protection circuit.
  • The noise level of the power from the low-noise standard output terminal is greatly reduced by passing through the 2-step noise filter and the output voltage is set to approximately 9.8 VDC in order to reproduce the condition of power being supplied from a brand-new battery.
  • The isolated output terminals can supply current higher than 1A momentary required by some digital effects units on boot.
  • Since the two isolated output terminals are completely independent each other and electrically insulated, no ground loop noise will occur. External digital noise via mains power supply lines is rejected.

NOTE

  • The supplied DC power cables are not applicable to effects units from Eventide® or LINE6®. Customers need to prepare suitable cables for use with such units.
  • Proper basic operations on the products noted above (DigiTech®, Eventide®, LINE6®, Strymon®) have been confirmed by FREE THE TONE (as of November 11, 2013). However this does not guarantee full operation of each product.
  • Due to modifications or minor changes that might be made by a manufacturer of those products after our confirmation, the above-mentioned products may no longer be compatible with the PT-3D. As a precaution, before connecting, be sure to confirm the power requirements of the device to be connected to the PT-3D.
  • The DC cable supplied with the PT-3D can be used with the following models.

Q & A

Q:If I connect a modulation or distortion effects unit to the high current terminal of the PT-3D, is noise level increased compared to the case where it is connected to the low-noise standard terminal?

A:Yes. If you are using a distortion effects unit, the noise level can rise a little. But it depends on the circuit used in it. For a modulation effects unit, the difference would be almost imperceptible because the gain is low.

Q:By using a polarity reversing cable, can I use the PT-3D to power a Fuzz that has a center plus power jack and operates correctly only when it is powered alone?

A:Yes. Since the PT-3D’s high-current terminal is isolated, it can be used for an effects unit driven by -9 V (i.e., a circuit that connects the power supply’s (+) side to the ground).
NOTE: The low-noise standard output terminal cannot be used for this application.
