Important note:

The z-K6 does not auto-detect the input sample rate. You must select the sample rate

manually. Please make note of this and always make sure that the selected sample rate

matches the incoming sample rate. This will change on subsequent firmware revisions.

Specifications................................ 12 Important note: The z-K6 does not auto-detect the input sample rate. You must select the sample rate manually. Please make note of this and always make sure that the selected sample rate matches the incoming sample rate. This will change on subsequent firmware revisions.

The user can also control the equalization of the ambience. In tandem, the z-K6 allows you to derive a lowpass-filtered mono sum of the stereo signal and send the result to the LFE channel.

Please don't forget the warning from the front-cover of this document: The z-K6 does not auto-detect the input sample rate. You must select the sample rate manually. Please make note of this and always make sure that the selected sample rate matches the incoming sample rate.

The z-K6 is also endowed with the ability to solo channels. If you press and hold one of the channel select buttons, that channel will solo -- i.e., the other channels will mute and you will only hear that channel.
Page 5 Please note: the front K-level control will rotate all the way through 90 degrees and back to 0 degrees so that you can readily compare the two extremes. Figure 4 - Front Ambience screen, two -channel mode There are eight algorithms for ambience enhancement. They are...

Figure 5 -- Front ambience screen, three -channel mode Please note: the focus control will rotate all the way through 90 degrees and back to 0 degrees so that you can readily compare the two extremes. You will find that between each of the algorithm positions on the control is an "off" position. The "off"...
Page 7: Controlling Front Ambience Equalization
From the LRC ambience screen press the "to LRS page" button to get to the surround page. Subsequently, pressing the system button will return you to this page. This page contains two parameters: the rear K-level and the LFE cut frequency, as shown in Figure 5. The rear K-level controls the amount of ambience extracted to the rear channels.

The entire state of the z-K6 can be saved and recalled. Press the load/save/MIDI button. This will bring the z-K6 to the state shown in Figure 9. To save a preset, use the left knob to choose a preset number then press the button beneath the SAVE indication. This will then bring the z-K6...
Page 9 There is one special preset that cannot be over-written. This preset is given number 00 and stores the z-K6 's "flat" settings. This is the preset you will want to use in order to return the z-K6 to a "blank" setting. If you attempt to over-write preset 00, the display will tell you that the preset was not saved and that you should choose another preset number.

MIDI channel. Press the button below the DUMP message on the screen. You will see a blinking asterisk next to the word DUMP. This lets you know that the z-K6 is sending its entire bank of presets, one at a time, to the MIDI sequencer via MIDI system exclusive commands.

Figure 13. Unlike most digital audio processors, the z-K6 does not auto-detect the input sample rate. Rather, you must select the sample rate manually. This will change on subsequent firmware revisions.
