Portaflex 500 manual

The high frequency output is flat at the center position. Fully counter-clockwise results in all direct signal no effect and fully clockwise adds all effect with no direct signal. The fully clockwise position is equivalent to a series effects loop and should be used with such devices as limiters and equalizers. It affects the preamp level to speaker and phone outputs. The incoming audio is mixed with the preamp signals, so you can play along to a practice track, as you listen with headphones.

It does not affect the signal fed to the audio input. The output here is a mix of the line-level signals reaching the amplifier, and any incoming audio from the audio in jack [17].

If you just want to listen and practice through headphones, disconnect the speaker-level outputs [23] from the speaker cabinet. Before putting on headphones, make sure the volume control [15] is turned down, and if connected any external audio source has its level turned down. The rated power output of the PF is watts rms into 8 ohms or watts rms into 4 ohms.

The output is not affected by the volume control [15]. This is a direct output not affected by any EQ or boost settings. With the switch in the OUT position, the signal is Post-EQ and is controlled and modified by the tone controls, and the effects loop.

Use the FX return jack to feed the returned processed signals back into the power amplifier. The processor could be fed by signals from the FX send [28]. This allows for silent tuning through an electronic tuner or killing the house send with a monitor mixer send still active.

When using an external source, connect the OUTPUT of the source to this jack using a shielded instrument cable to feed the signal into the power amp section. The internal signal is disconnected when a plug is inserted into this jack. The Mute function is available from either the front panel or the footswitch. Be sure to ask for model AFP2. The higher the signal level, the louder and hotter it gets.

It is important to dissipate the heat as quickly as possible. This results in increased reliability and longevity for the amplifier. The amplifier module is mounted on a large heatsink, which is cooled by convection where cool air is drawn through its fins, carrying the heat away. In order for this convection cooling to work efficiently, it is important to provide adequate airspace behind and to the side or above the amplifier. When positioning the Portaflex, we recommend leaving at least six inches of air space behind it.

When the amplifier has cooled down to a safe operating temperature, the fault switch resets itself, and the Portaflex resumes normal operation. If the fault switch activates frequently, try turning down the volume control a notch or two to avoid overheating the amplifier.

Flip-Top Instructions: It is accomplished in five simple steps: Step 3: set the cabinet top handle-side down on the top of the cabinet. The amplifier should now be on the top, rightside up, with the front of the amp and the front of the cabinet facing the same direction. Step 1: loosen the latches on each side of the cabinet. There are two latches on each side, four total. Step 5: rock out like there is no tomorrow! We will instruct you on how to do the latter, as we are not in the business of lid-flipping!

Step 4: line up and lock all four latches. SW Rev. Total views 1, On Slideshare 0. From embeds 0. Number of embeds Downloads 2. Shares 0. Comments 0.

Nice warm tone. But one thing that I noticed is that when I played slap style bass the circuit protection would kick in and shut the amp down for about 15 seconds. I contacted GC and they had heard that this was happening and that it was just an overly protective circuit.

I then contacted people that I know and trust from St. Louis Music who used to build Ampeg amplifiers right here in St. They knew about the issue and also that Ampeg had developed an IC chip that would fix the problem. It allowed normal input spikes that would occur during slap style playing but used I put it in their shop for a free warranty repair and upgrade.

A few weeks later it came back and worked wonderfully The known shut-down issue was gone and the amp sounded wonderful through all styles of playing. I have used the amp in small to medium venues over the past year without a single issue or problem. I am now out playing large stages using a Ampeg SVT and an 8x10 cab.
