M2 User Manual

When monitor has acquired any station in TUNER BAND mode and SELECT switch is held for three

seconds, monitor enters PRESETS store mode and PRESETS arrow LED flashes. UP and DN controls

then allow user to scroll through A1 through A20 and F1 through F20 dependant on band. When the

desired preset location is indicated on VFD, next momentary push of SELECT switch stores selected

station in that PRESETS position.

Mode - Service Control. MODE - SERVICE control selects AUTO or ANALOG mode, and activates

multicast tuning when an HD Radio

multicast signal is present. In the AUTO mode, the monitor will

receive an HD Radio

digital broadcast if one is being transmitted; if not, the monitor will receive the

analog broadcast. The MODE - SERVICE LED illuminates when only the mode is active or when the

switch is being pushed. Default mode is AUTO.

When tuned to an HD Radio

broadcast and at least one multicast signal is present, momentarily

depressing the MODE – SERVICE switch selects the multicast tuning mode; the M4 is automatically

tuned to the first multicast broadcast, probably HD-2. The UP and DN controls can then be used to tune

to the other multicast stations; i.e., HD-3 through HD-8, available on that RF frequency.

When tuned to an HD Radio

broadcast and the MODE - SERVICE switch is depressed for 5

seconds, the monitor is forced into ANALOG mode; the audio outputs along with demodulation and

carrier modulation level meters process only the analog portion of the HD Radio

broadcast.

Forcing Control. The FORCING control is used to select A-D SPLIT mode, functional with AM or FM

HD Radio

signals. When locked to an HD Radio

signal, momentary push of FORCING switch puts

monitor in A-D SPLIT mode. In A-D SPLIT mode, the analog audio outputs and headphone jack

provide left analog program audio in the M2 left channel and the left HD Radio

audio program in the

M2 right channel. The Left Demodulation Level meter then displays the analog audio signal while the

Right Demodulation Level meter displays digital audio signal. This mode provides for audio phase

matching as well as audio level and time-alignment of the HD Radio

broadcast for the correct analog

diversity delay. FORCING LED illuminates when monitor is in FORCING mode. Subsequent

momentary push of FORCING switch turns FORCING mode and FORCING LED off. Default mode is

off.

When tuned to an HD Radio

broadcast and the FORCING switch is depressed for 5 seconds, the

monitor is forced into HD-1 DIGITAL-only mode; the M2 is then locked only to the HD-1 broadcast.

There is no DIGITAL-only mode for multicast broadcasts.

Demodulation Level Measurements. The 58-segment demodulation level LED meters display the

relative audio levels for the HD Radio

station MPS, multicast or analog AM / FM signal indicated on

monitor’s VFD.

For HD Radio

MPS and multicast digital audio, the Demodulation Level Select switch is inhibited and

the Left and Right digital audio levels are displayed; the level meters are calibrated from -64dBfs to

0dBfs, marked as 0dB on the M2 front panel. (Please note this calibration takes into account the 6dB

of headroom found in most HD Radio

exciters.) When an HD Radio

station is being acquired but

prior to an HD Locked LED indication, the analog attributes of the HD Radio

signal are displayed on

the Demodulation Level meters. To measure the analog attributes of an HD Radio

signal after

acquisition, use the MODE - SERVICE control as described above.
