DPX-3070/3070B 8 How to enter the test mode In order to enter the test mode, while pressing down ATT + WOW keys simultaneously, press SRC key. Test mode conditions The test mode starts up when STANDBY source is selected.

37、The volume value is 10dB. (30 on the display) Beep prohibited. All lights displayed. (3-color LED lights up for all three col- ors. (white lighting) WOW : OFF EQ : Natural Test mode (Source : CD) When starting disc loading, tracks will be played starting with the Track No. 9. The key operations belo

40、While the source is being displayed, clicking once on the EQ/AUD key will cause the unit to enter Adjustment Mode. When 1 key is pressed: Flat When 2 key is pressed : Full-boost When 3 key is pressed : Full-cut The settings for Q, Feq, and Ex are fixed. Q2.0 BassFeq150Hz ExtON Mid Q2.0 Feq1kHz Trebl

41、eFeq10kHz Test mode (Audio adjustment) While the source is being displayed, long-clicking on the EQ/AUD key will cause the unit to enter Adjustment Mode. By toggling on the FM and AM key, the items below can be selected and adjustments can be made with and keys. The balance adjustment is set for thr

The other cases

43、will be the same as the DC offset specifications. Test mode (Display of DC offset detection results) When in this mode, the mode for “Display of DC offset de- tection results” will be added in the MENU items at the time when Test Mode Standby is the source. This will make it possible to confirm resu
