Maintenance and Care | Hughes & Kettner DSM instruction

ZENTERA-MANUAL

Turn WTYPE until FOOTSWITCH ASSIGN appears in the display. Select UP, DWN or TGL using the WPARA 1 or WPARA 2 knobs. If you opt for the TOGGLE function, see section 6.5 above for further instructions.

7.13 VOLUME PEDAL

This menu lets you determine at which point in the signal chain a connected volume pedal or the volume pedal of the optionally available Z-Board regulates the amp’s level.

Turn WTYPE until VOLUME PEDAL appears in the display. Using WPARA 1 or WPARA 2, select the desired mode from the following options:

AMP VOLUME: With this option, the pedal controls the amp section’s Volume knob, meaning that it adjusts the pre-effect section volume level. The volume value programmed in the preset has priority when you change a preset, and it is activated first. The level will not change until you operate the pedal. GLOBAL: With this option, the pedal controls the amp’s Master knob, meaning that it adjusts the overall output level. Even if you change a preset, the level is still determined by the pedal, or more accurately, its current value.

Note: For an in-depth explanation of the workings of the Z-Board, please consult the Z-Board owner's manual.

7.18 Z-BOARDCALIB

As described above in section 7.16 for a connected expression pedal, you can also calibrate the optional Z-Board.

Proceed as follows:

Turn WTYPE until the Z-BOARDCALIB SET WAH MIN menu appears in the display. Set the wah-wah pedal of the Z-Board so that it rests at its minimum position (with the heel all the way back and the toe pointing up) and confirm by tapping rPARA 1 or rPARA 2. The display automatically pages to the next menu, SET WAH MAX. Floor the pedal so that it rests at its maximum position and tap rPARA 1 again.

The display automatically pages to the next menu, SET VOLUME MIN, which lets you calibrate the volume pedal. The procedure is the same as for calibrating the wah-wah pedal. Set the volume pedal so that it rests at its minimum position and confirm by tapping rPARA 1 or rPARA 2. The display automatically pages to the next menu, SET VOLUME MAX. Floor the pedal so that it rests at its maximum position and tap rPARA 1 again.

7.14 VOLUME PEDAL RANGE MINIMUM, VOLUME PEDAL RANGE MAXIMUM

If you have connected an expression pedal to the jack on the rear panel of the zenTera®, you can define the desired volume control range for the pedal in these submenus. The same of course holds true for the volume pedal on the optionally available Stageboard.

Turn WTYPE until the appropriate menu appears in the display. Select values between 0.0 and 9.9 using the WPARA 1 or WPARA 2 knobs.

7.15 CV PED TYPE

This menu lets you select a linear or a logarithmic action for your foot pedal's control range (linear = uniformly increasing volume, logarithmic = at first a steep and then a flatter rise in the volume curve).

Turn WTYPE until CV PED TYPE appears in the display. Select LINEAR TYPE or LOG TYPE using WPARA 1 or WPARA 2.

7.16 CV PED CALIB MIN/MAX

You can calibrate a connected expression pedal here. Turn WTYPE until the CV PED CALIB SET TO MIN menu appears in the display. Set your foot pedal so that it rests at its minimum position (MIN, with the heel all the way back and the toe pointing up) and confirm by tapping rPARA 1 or rPARA 2. The display automatically pages to the next menu, CV PED CALIB SET TO MAX. Floor the pedal so that it rests at its maximum position and tap rPARA 1 again. Your pedal is now calibrated and ready to “rock”.

7.17 Z-BOARD BANK CHANGE

This menu lets you define how the zenTera® responds to bank change commands sent from the Z-Board. This command can either access a preset of the next bank directly, meaning that the preset is activated immediately along with the bank change. Note that in this case the Z-Board switches in increments of five. This means that if you are currently using preset 23, a bank chan- ge command automatically activates preset 28. If you do not want presets to be switched in this manner, you can opt for pure bank change functionality. In this case, the next bank is always called up without accessing a preset directly. You then have to activate one of this bank's presets separately by stepping on the appropriate switch on the Z-Board.

Turn WTYPE until the menu appears in the display. Use WPARA 1 to select DIR for the former, BNK for the latter option.

7.19 VERSION

This menu tells you which software versions the individual modules of your zenTera® are running.

Turn WTYPE until the menu appears in the display. Then you can call up the versions with WPARA 1 or WPARA 2.

8.0 MAINTENANCE AND CARE

The zenTera® does not require service of any type. There are however a few basic rules that will extend the service life of your amp enormously:

•Make sure all peripheral devices, cords and cables are in a state of good repair! Defective speaker cables are the most common cause of power amp failure. Poor-quality cables will cause hum and undesirable noise.

•Ensure plenty of air can circulate around your amp's ventilation ducts at all times.

•Definitely avoid exposure to mechanical shocks and extreme heat, dust and particularly moisture.

•Be picky about the kind of peripheral devices you connect to your amp and always check out their specs before you plug them in. Never connect speaker cabinets with an ohm rating lower than the zenTera® is designed to handle. Under no circumstances should you connect devices with high output signal levels (e.g. power amps) to your amp's input.

•Be sure the AC power source delivers the current that your amp is designed to handle before you plug it in. When in doubt about the local rating, ask the venue's sound technician or a stage hand.

•Refrain from DIY repairs! To be on the safe side, you should also have a qualified technician replace internal fuses.

9.0POSSIBLE ERROR SOURCES/ TROUBLESHOOTING

E1) The zenTera® won't power up when you switch it on:

•It's not getting AC power. Check the mains cable to see if it is connected properly!

•The mains fuse is defective. Replace the fuse with another identical fuse. If this fuse also blows, be sure to talk to your local Hughes & Kettner dealer.
