Introduction

The DaySequerra M4 HD Radio available with built-in multicast capability. The M4 has been designed as the benchmark in sensitivity (< 5.0dBf in FM) and reliability, and at the same time delivers the highest quality, accurate monitoring of existing analog and HD Radio >90dB for HD Radio

FM signals).

Just like its larger sibling, the DaySequerra M2.0, the M4’s ultra low noise RF front-end with built-in preselector and double-balanced mixer, low-jitter DAC and Class-A biased audio outputs provide the highest fidelity reception and demodulation of HD Radio applicable data (PAD) for MPS and SPS multicast signals.

Its robust, modular architecture ensures that the M4 will never become obsolete. The rugged M4 chassis houses dedicated hardware RF, audio and power supply modules that, along with firmware updates via flash programmable memory, completely anticipates the growth of new HD Radio services and programming. This design approach along with our product update program ensures that a broadcaster’s investment in a DaySequerra product will continue to pay off well into the future.

Please read this manual thoroughly before operating your M4.

M4 Operating Description

Power-up and Standby. The Power switch is located on the rear panel of the M4; when switched on the tuner displays the hardware and software version for your M4 to be displayed for 3 seconds on the M4’s VFD.

In any mode, if the SELECT and DN switches are depressed simultaneously for 5 seconds, tuner goes into Standby mode with all front panel controls and indicators blanked except for SELECT and UP

switches; the M4’s VFD then indicates the “DaySequerra Standby” message. Holding SELECT together with UP switch in for 5 seconds when in this Standby mode unblanks all front panel controls and indicators and returns tuner to normal operation.

In STANDBY or master power (rear panel AC switch) off, last station is displayed and all tuner control/status returns to its default state.

Front Panel Locked. In any mode, if SELECT and MODE – SERVICE switches are depressed simultaneously for 5 seconds, tuner goes into Front Panel Locked mode i.e., all front panel controls are inhibited except for UP and SELECT switches; analog and digital audio outputs continue. VFD alternates between displaying FRONT PANEL LOCKED and normal display for tuned station. Momentary simultaneous push of SELECT and UP switches in Front Panel Locked mode unblanks all front panel controls and indicators, and returns tuner to normal operation. VFD displays “Exiting Front Panel Locked Mode” message during tuner state transition.

Audio Muting. The M4’s audio output can be set to automatically mute for received signals with signal strength less than 45dBf. The audio muting can be enabled using the DATA - DISPLAY menu described above.

Tuner Band Control. TUNER BAND control toggles between manual AM and FM tuning. TUNER BAND arrow LED illuminates only when mode is active. Audio muting is active while tuning.

Presets Control. In PRESETS tuning mode tuner has ability to store 20 AM stations and 20 FM stations including FM-HD multicast signals.

Preset stations are stored for recall in positions A1 through A20 and F1 through F20 respectively for AM and FM bands. PRESETS Arrow LED illuminates when tuner is in PRESETS tuning mode. UP and DN scroll through the preset stations stored for the band selected. Audio MUTING is active while scrolling through preset stations. Second momentary push of PRESETS switch changes tuner band.

When tuner has acquired any station and SELECT switch is held for three seconds, tuner 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 receive an HD Radio

digital broadcast if one is being transmitted, if not the tuner 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.

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

signal. When locked to an HD RadioTM signal, momentary push of FORCING switch puts tuner in A-D SPLIT mode. In A-D SPLIT mode, the analog audio outputs and headphone jack has analog audio signal in left ear and digital audio signal in right ear. This mode permits user to monitor the time-alignment of the HD Radio

broadcast for the correct analog diversity delay. FORCING arrow LED illuminates when tuner is in FORCING mode. Subsequent momentary push of FORCING switch turns FORCING mode and FORCING LED off. Default mode is off.

Data – Display. The DATA - DISPLAY control is only functional with HD Radio DISPLAY arrow LED illuminates when mode is active. DATA - DISPLAY switch selects PAD data from the current HD Radio

station MPS or multicast signal to be displayed on tuner’s VFD. Momentary

signals. DATA -

push scrolls through each PAD field in the following sequence:

• Station long name

• Station program type

• Song title

• Artist

• Album

• Genre

• Comment

Subsequent momentary push of DATA - DISPLAY switch turns DATA - DISPLAY mode and DATA DISPLAY LED off. VFD display second line scrolls if longer than 16 characters. If there is no data for the selected field, VFD display “NO” plus the data category e.g. “NO ALBUM DATA.”

Station long name, station short name and program type are processed as an ID3 tag. HD Radio

PAD data, i.e., song title, artist, album, genre and comment fields are limited to 127 bytes each for a total of 1018 bytes per message per iBiquity specifications. For more information on ID3 tags and PAD data, please visit www.ibiquity.com and www.id3.org.

UP. Momentary push of UP control tunes frequency up one increment in TUNER BAND mode, when held for three seconds tunes faster. UP selects next stored preset station in PRESETS mode (no faster mode, one push per preset). Selects next item in other menus and is used for other functions as described herein.

DN. Momentary push of DN control tunes frequency down one increment in TUNER BAND mode, when held for three seconds tunes faster. DN selects next stored preset in PRESETS mode (no faster mode, one push per preset). Selects next item in other menus and is used for other functions as described herein.

Select Control. When tuner has acquired any station and SELECT switch is held for three seconds, tuner goes into PRESETS store mode; PRESETS arrow LED flashes. UP and DN controls then allow user to scroll through A1 through A20 or F1 through F20, dependant on band. Once user has selected desired PRESETS position, next momentary push of SELECT switch stores selected station in that PRESETS position.

Multicast Tuning. When tuned to an HD Radio

broadcast with at least one multicast SPS signal present, momentarily depressing the MODE – SERVICE switch puts tuner into MULTICAST TUNING mode. Use the UP and DN controls to scroll through each of the multicast stations available. The DATA - DISPLAY switch selects PAD data from the tuned multicast broadcast to be displayed on tuner’s VFD.
