Vertex Standard FT-1000MP manual Using Headphones for Dual Receive, Headphone Audio Adjustments

Operation

USING SUB VFO B

Balance - The AF GAIN knob adjusts the volume for both the Main and Sub VFOs simultaneously. The small SUB AF now functions as a “balance” control between Main and Sub audio levels.

Note - To “reverse” Main and Sub receiver audio at any time, press the [AF REV] button just to the left of the DOWN(q)/UP(p) keys so its LED lights. The func- tions of the AF GAIN and small SUB AF controls are now switched. Press the button again to return to nor- mal operation.

Remember that when the Sub VFO is turned off by pressing [DUAL] again, the AF GAIN control configu- rations no longer apply.

Using Headphones for Dual Receive

To take advantage of dual reception, you will want to connect stereo headphones to the PHONES jack. Like the AF GAIN control, headphone audio mixing can also be configured as desired from menu selection 4-8. Three audio mixing schemes are selectable as follows:

Mono - Audio from both the Main and Sub receiver is combined equally in both ears (as from the loud- speaker when headphones are not used).

Stereo 1 - This is a combination of the audio from the two receivers and it gives you some audio from each channel in each ear, but with the Main receiver emphasized in the left ear, and the Sub receiver em- phasized in the right ear, resulting in a kind of “3-D” spatial audio effect.

Stereo 2 - Audio from the Main receiver is only heard in the left ear, and audio from the Sub receiver is heard only in the right ear.

Note that both the Main and Sub VFOs must be activated (to put the MARK-VFT-1000MPinto the dual receive mode), and the AF GAIN control(s) must be balanced (centered) to hear both receivers. Compare these two positions with both VFOs tuned to signals, to select the audio mixing scheme you prefer.

Also observe that the VRF, EDSP, RF GAIN, SHIFT, WIDTH, NOTCH, and AGC functions do not affect the sub receiver (AGC is automatically selected according to mode, or else from menu selection 8-7).

Headphone Audio Adjustments

The Main and Sub receiver audio levels available from headphone jacks A and B are manually adjust- able. Underneath the top panel access cover are four trimpots allowing individual adjustment of Main and Sub audio for each headphone jack. With a headphone in- serted into the appropriate jack, you can rotate these controls using a small insulated screwdriver for opti- mum level and balance. Refer to the drawing below for trimpot locations.
