OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION

Dither

The DS1-MK2 v2.0 is able to apply POW-R type dither algorithms to avoid distortion when re- quantizing from 24bit to 16bit or 20bit output word length (see TECHNICAL DATA for dither specifications).

To toggle dither on/off, press key D twice. To see dither status refer to the status display (see

Word Length

To set output word length, press key D and select the appropriate wordlength.

Setup

Press key D then chose the setup menu. This leads to the menu where the type of POW-R dither can be chosen (see TECHNICAL DATA for dither specifications). Also selectable is:

Auto-Blacking

If auto-blacking is activated by marking the “0 IN

à0 OUT“ option, dither will be turned off if the input signal is zero As soon as the input signal changes, dither will be turned on again. This en- sures that pauses between programmes are still digital zero, even if dither is activated.

Display Resolution

The magnitude of the overall frequency response of the EQ1 is drawn on the LC display. This im- mensely facilitates filter parameter adjustment because it takes one look to see what the equal- izer is doing instead of having to work it out from the parameter values.

To obtain the maximum benefit from the graph, set the vertical display resolution to a range that just covers your settings. There are four ranges available:

±6dB, ± 12dB, ± 18dB, ± 24dB

To change the display resolution, press the “menu” key, then select “Display”. Choose a

range that suits your curve and press the “menu” key again to return to the status display.

LCD Contrast

To change the display contrast, press the “menu” key, then select “Display”. Adjust contrast with the “gain/ data” encoder.

EQ Bypass

The EQ1 can be completely bypassed with the green “bypass” key below the mains switch. If the “bypass” key is lit, the EQ1 is absolutely trans- parent, making the output signal bit equal to the input signal.

While bypass is active (key is lit), the EQ1 works in preview mode. This allows you to change pa- rameters without actually affecting the audio sig- nal. The frequency curve is drawn outlined over the flat bypass curve, so you still get the advantage of the graph when modifying parameters.

As soon as bypass is deactivated, the outlined curve takes effect.
