5.6 Footswitch

Speaker Out

Connect the optional two-way footswitch (Hughes & Kettner® FS-2) to this jack for switching the FX LOOP and PUNCH.

5.7 Speaker Out

Connect speakers to the Speakon jack. Please make sure to wire the cable correctly (1+=+, 1-=-) and to match the impedance of the QT600 to the connected speaker

(Chapter 4.2 IMPEDANCE SELECTOR).

7. Troubleshooting

The amp won’t power up when switched on.

•Check the mains cable to see if it is connected properly.

•Check the mains fuse. If it is defective, replace it with another fuse with identical ratings. If the defect recurs, consult your local authorised Quantum™ dealer.

The amp is correctly cabled, but no sound is audible.

•Check to see if the MUTE control is activated.

•Check the setting of the GAIN and MASTER controls.

•Check the effects circuit. An inactive or incorrectly cabled effects device can interrupt the signal.

•Check the headphones output. If headphones are plugged in, the speaker output is muted.

The DI OUT causes humming noises when in use.

•The earthing of the connected equipment is causing a ground loop. Never sever the equipment’s safety ground! Instead, set the GROUND switch to LIFT. If this fails to resolve the problem, try plugging both devices into the same power distributor.

•An electrical or magnetic field is generating interference.

Use a better quality cord or try to skilfully reposition the cables to minimise interference.

Feedback arises when DI OUT is in use.

•If the PA’s sound pressure is extreme enough, it can excite the amp’s speaker and cause feedback when DI OUT is in use. Since the speaker’s response influences the amp, it could be routing the interference signal to the DI OUT. Solution:

Try repositioning the amp or using the LINE OUT instead.

When connecting a mixing console to the DI OUT jack the signal sounds totally distorted over the PA.

•The mixing console’s input is not set to line level. Adjust the level accordingly at the mixing console. If this is not possible, either patch the signal to an unbalanced (line) input at the mixing console or use a connecting cable equipped with an integrated balanced voltage divider (available from quality music stores

or PA service companies).

The amp’s output level is too low.

•A device connected to the effects loop is reducing the signal level. Adjust the signal level using the effects device’s input/output control.

The amp doesn’t sound the way it usually does.

•Check the impedance matching. Mismatching has a negative effect on the tone quality of the Dynavalve amp.

QT600 specifications

The Quantum QT600 is an advanced quantum computing system designed to revolutionize the way complex computations and simulations are executed across various industries. This state-of-the-art device leverages cutting-edge quantum technologies to deliver unprecedented processing power, enabling researchers and enterprises to tackle problems that were previously deemed unsolvable.
