ZENTERA-MANUAL

REAR PANEL

MAINS IN:

Connect the factory-included mains cord to this

socket. Ensure the amp's voltage rating matches your local AC
voltage rating before you plug the cord into the wall socket (see
11.3). The mains fuse bracket is located next to this the socket.
When replacing blown fuses, make sure you use specified
replacement fuses only (see 10. TECHNICAL SPECIFICATIONS).

SPEAKER LEFT/RIGHT:

The

zenTera

is equipped with stereo outputs

for the internal loudspeakers as well as for the connection of
extension cabinets. When you opt to connect external cabinets,
make absolutely sure that the overall impedance does not fall
below the minimum permissible impedance of 6 ohms per chan-
nel. This means that you can connect, for example, a cabinet
with at least 8 ohms in addition to the internal loudspeaker.

The following table indicates the possible speaker connection
options for each channel:

Jack 1

Jack 2

Internal 16 ohms

External 16 ohms

Internal 16 ohms

External 8 ohms

External 16 ohms

External 8 ohms

External 16 ohms

External 8 ohms

Note: Read section 7.2, MODE, to find out how to adjust the
zenTera

to the given speaker configuration.

EFFECTS LOOP:

Serial stereo/stereo insert for connecting

external effect devices. In the signal chain, the EFFECTS LOOP is
located after the D/A converter and in front of the power amp
volume knob.

Note: Bear in mind that the overall sound quality depends to a
considerable degree on the quality of the external effect device
since the entire signal is routed through it in series.

• SEND:

Connect this output to the input of your effect device.

In view of the fact that they route out signals without speaker
simulation, the SEND jacks may also be used as a line out for
connecting external power amps.

• RETURN:

Connect the output of your effects device to this jack.

You can also use the RETURN jacks to connect an external
signal source such as an audio playback device. However,
keep in mind that in this case the

zenTera

's signal is muted,

which means that if you patch in an external signal here, you
can’t play along with it over the

zenTera

HEADPHONES:

Connect headphones to this jack. You can control

the volume of the headphones output separately. Like the
RECORDING OUT, this circuit features speaker simulation that
replicates the sound and setup of the original amp.

Note that the internal loudspeakers are not disconnected
automatically when you plug in headphones. If you want to
mute the zenTera

's speakers, turn the MASTER volume knob

all the way down.

RECORDING OUT:

Analog and digital stereo output for

connecting the

zenTera

to a mixing console or a PC.

Note: The EFFECTS LOOP is not routed to the RECORDING OUT.

• ANALOG LEFT/RIGHT: Patches out the RECORDING OUT signal

at line level with integrated simulation of the original amps'
speakers.

• DIGITAL S/PDIF: The digital version of the RECORDING OUT

(24 bits; 44,1 kHz sampling rate).

STAGE BOARD:

9-pin port designed to take the optional Hughes &

Kettner Z-Board or the optional FS-5, a 5-way foot switch.

Note: This is not an interface for connecting a PC.

MIDI IN/OUT/THRU:

Standard MIDI trio. Connect a standard MIDI

board here. It also serves as the interface for loading software
updates and creating preset backups. The IN port is powered via
a phantom power circuit equipped with a discrete fuse.

FOOTSWITCH:

Stereo jack for connecting a 1-way or 2-way sustain

pedal. It lets you switch to the next higher preset number (UP) or
next lower preset (DOWN) or also back and forth between two
presets (TOGGLE). For the latter alternative, you have to assign a
marker to one of the two presets (see 6.5, FOOTSWITCH). Go to
the system menu (see 7.12, FOOTSWITCH ASSIGN) to select the
desired UP/DOWN/TOGGLE function.

Note: The zenTera

detects the polarity (1-way or 2-way) of the

connected sustain pedal when it is switched on.

FOOT PEDAL:

Stereo jack designed to take an expression pedal

such as a volume or wah-wah pedal. The volume function is the
default setting unless you assigned a wah-wah effect for the
given preset in PRE EFFECT MODE. (see 6.1, PRE EFFECT MODE).
