4.2 Master

The MASTER knob determines the overall level of the amp.

But it’s more than merely a volume knob – in combination with the GAIN control, it makes a wide range of nuances between clean and overdrive-sounds possible.

4.2 Impedance Selector

On the reverse of the QT600 there is a selector switch for matching the QT600 to the impedance (load, resistance, “ohm number”) of the connected speakers. The following combinations and settings are possible:

Impedance Selector

To achieve full sound quality, correct impedance matching absolutely must be assured, as mismatching prevents the optimal functioning of the Dynavalve™ concept. An incorrectly matched impedance leads to incorrect feedback between the amp and speaker, which results in unsatisfactory tone or inadequate volume.

Note:

Speaker cabinets are generally in parallel. To calculate the total resistance of two parallel speakers (R1, R2), multiply the individual resistances, and divide the resulting product by the sum of the individual resistances. The following formula applies:

R = ( R1 x R2 ) / ( R1 + R2 )

For example, for an 8 ohm and a 16 ohm speaker:

R = ( 8 x 16 ) / ( 8 + 16 )

R = 128 / 24

R = 5.33

and controls

5.1 Fx Loop

The effects loop is a serial circuit, located after the TUBE GROWL knob and before LINE OUT in the signal path. Because the signal from the effects device is patched through serially, the effects balance must be adjusted on the effects device itself. The effects loop is footswitchable (Hughes & Kettner® FS 2).

Fx Loop

Send

Connect this output to the input of the effects device.

Return

Connect the output of the effects device to this input.

5.2 Line Out

This unbalanced line output patches out the preamp signal inclu- ding effects. Located before the Dynavalve™ amp in the circuitry, it is independent of the MASTER control setting.

Note:

This output does not patch out the sound of the Dynavalve™ amp and is thus ideal for routing the signal to another amp.

5.3 Di Out

Use this balanced output to connect the QT600 to a mixer or stage speaker. There are two modes to satisfy the needs of professional on-stage use:

Pre-EQ

Set to PRE, the DI-OUT reads off the signal directly after the preamp, making it possible to adjust stage sound and volume independent of the mixer/PA.

Post-EQ

Set to POST, the DI-OUT reads the signal off “at the speaker,“ patching the full amp signal including effects and EQ through to the mixer. The signal is thus dependent of the MASTER control setting, and is shaped by the reciprocal action of speakers and amp so decisive in determining the Dynavalve sound.

DI Out

Ground switch

Activating the GROUND switch isolates the ground of the DI-OUT signal from the ground lift, making it possible to suppress hum should it occur.

5.4 Tuner

Connect a tuner to this output, which is always active. The MUTE button can by pushed for muted tuning.

5.5 Headphones

Connect headphones to this jack. The QT600 speaker output is deactivated when a plug is inserted into this jack.
