This means that each product, while maintaining a similar appearance, cannot be the same as the other, since the particular "hammered"...
  • Page 7 The Guru’s Advice 1) Connect the main power to 12Vdc (min 500mA). Make sure the power supply is negative tip. 2) Connect the “Output” to the amplifier “Input”. 3) Connect the “Input” to the instrument. 4) Set the “Input Volume”. The input volume is displayed by "Input Level" and can be adjusted from super clean to overdrive.
  • Page 8 One example in Rep. mode: If you select the “5 position” switch, call together the fourth and third heads, it will mean the 4th Head considered as an 8th note, and 3rd head is equal to a dotted 8th. If you use the “varispeed” you can keep the synchronism by increasing the delay time over 100%.

  • Page 13: Block Diagram

    Block Diagram: The diagram 1 represents the principle mode of the function selector (Echo- Rep. - Swell) and the head selector. It must be considered that the latter works in relays interfacing to provide a quieter commutation. Block diagram 1...
  • Page 14 The diagram 2 is the complete operating system. As you can see the valve returns to be used both on the input and output stage, with great benefits on the sound. The dynamics of the signal was more high, thanks to the voltage doubler, which in this way allows not to saturate the input in combination with a big signals.
  • Page 15 Input Instruments Connection: 
 To the Input you can use many different instrument lo and hi impedance as: Guitar, bass, mic preamplifier, keyboards, etc. The input control must be adjusted so that you can use the right amount of signal. The input level (magic eye) will help you understand how to adjust the levels.
  • Page 16 The Pompeii PE603 can be used with different types of instruments with output signals max 1Vpp and high or low impedances.The Old Italian echo was used as the main PA effect and shortly thereafter along with many instruments of the band. Today Pompeii wants to retrace those steps by offering wider compatibility even with the most modern instruments.
  • Page 17 The Echo in Front the Amp: The use of the echo in front of the amplifier is one of the most classic configurations. Thanks to a powerful input and output buffer we can send a good and clean signal to the amplifier. The use of good quality cables is always recommended.If you use Fuzz, Od.
