Phantom Tech Guitar Amplifier owner manual Load Amp Setting

Page 6

If you are using two speaker cabinets, you should reduce the impedance to half that of the impedance of the cabinets. For example, if you are using two 16ohm cabinets, your impedance selector should be set to 8ohms, not 16 (if you were using only one 16ohm cab, you’d set the impedance selector to 16). So, for example:

Load

Amp Setting

1 cab @ 16ohms

16ohms

1 cab @ 8ohms

8ohms

2 cabs @ 16ohms

8ohms

2 cabs @ 8ohms

4ohms

Never use your amp without a load! Doing so is likely to damage your amp!

Instrument. Plug your guitar into the input jack (duh!). When doing so, remember, your cable DOES matter. Always use a high quality cable when possible. Try to remember that when a cable is plugged into the input of the amp, it’s always best to make sure it’s also plugged into a guitar. Otherwise, you assuredly encounter lots of popping and annoying sounds.

Effects loop. Your effects loop is a series loop with a “shorting” jack in the Return position. What does this mean to you? When you plug a cable into the effects return, it goes active. When you unplug the cable in the Return position, the loop return goes inactive.

If you are using, for whatever reason, your amp just for its power stage, no problem. When you plug into the loop return, you’re set. When you do, the E. Return knob on the front panel becomes the power stage (master) volume (more on this later).

If you are using, for whatever reason, your amp just for its preamp stage (e.g., your amp’s preamp stage will be feeding another power amp instead), you should put a shorting jack into the Return jack. You should also ensure that the E. Return knob is set to 0. Note, if you run your amp this way, it is highly recommended that you pull all 4 power tubes out of the amp or ensure the amp has a load on it. When the amp is used in this manner, the particular channel volume control becomes that channel’s “master” volume, which is functionally operating as the loop “send” level.
