Introduction

The DaySequerra M3 HD Radio

Multi-Tuner is the first broadcast quality monitor available with three AM/FM tuners each complete with multicast capability. The M3 has been designed as the benchmark in sensitivity (< 15.0dBf in FM) and reliability, and at the same time delivers the highest quality, accurate monitoring of existing analog and HD Radio

AM and FM broadcast signals (THD+N <.005%

with stereo separation >90dB for HD Radio

FM signals).

Each of the three independent tuners in the DaySequerra M3 features an 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

programs, including display of

program applicable data (PAD) for MPS and multicast signals, including Apple “Buy Button” UFID.

Its robust, modular architecture ensures that the M3 will never become obsolete. The rugged M3 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 M3.

Unpacking"and"Installing"the"M3

Immediately upon receiving your M3, please make a careful inspection for any shipping damage. If damage is found or suspected, please notify the carrier at once and then contact your dealer.! ! The DaySequerra M3 is shipped in one carton, which contains: the M3 unit, an AC power cable and this User Manual.

We strongly encourage you to save the shipping carton and shipping materials supplied with your M3. They are specially designed to properly protect your M3, and in the event that you need to return it for service, only these OEM shipping materials can ensure its safe return to our factory.

We provide a limited 1-year warranty on all of our products, but if you don’t register your unit, it’s hard for us to help you if and when help becomes necessary. So please take a few minutes to complete

the warranty registration form on our web site, www.daysequerra.com. Thank you!

Rack Mount Installation. The M3 chassis has four rack mounting holes in its chassis and has been

designed to fit in a 19” standard 2RU space. Plastic ‘finishing’ washers are recommended to protect the painted finish around the mounting holes.

Power Connection. The AC power cable supplied with M3 must be connected from the M3’s IEC320 power entry module to an AC mains outlet with a functional earth ground connection. The M3 has been set at the factory to operate at 120VAC unless otherwise specified on the shipping carton. Please

connect your M3 to an uninterruptible power supply (UPS) to protect against power surges and brownouts.

Audio Output Connections. Balanced analog audio outputs are on male XLR connectors on the M3

rear panel with pin 1 GND, pin 2 HIGH (non-inverting) and pin 3 LOW (inverting).

The M3 digital audio output is transformer isolated in AES consumer format on a male XLR connector on the rear panel with pin 1 XFMR, pin 2 XFMR and pin 3 GND.

Front"Panel"Controls"and"Indicators

The M3 front panel consists of three independent HD Radio

tuner areas, with each area containing the following ‘dedicated’ controls and displays: VFD, 4 indicator LED’s and 3 control pushbuttons. The front panel also contains two ‘shared’ switch panels, each consisting of 5 indicator LED’s and 5 control pushbuttons for directing commands to one of the M3’s three individual tuners based on the Tuner 1, 2, 3 switch selection. The functions of ‘dedicated’ and ‘shared’ controls and displays are described below.

Dedicated Controls and Displays

The following controls and displays are ‘dedicated’ to their respective tuner as defined on the M3 front panel.

Vacuum florescent display (VFD) – Multi-function display that indicates current tuner band, frequency, mode, HD Radio

SIS and PAD data, and RDS/RBDS data from analog FM broadcasts.

Also used to display Mode Service, Forcing and Data Display menus.

M3#User#Manual#

UP and DN – For manual AM and FM tuning in TUNER BAND mode and scrolling through PRESETS in PRESETS mode. Also used to navigate Mode Service, Forcing and Data Display menus, as described below.

SELECT – Multi-function switch for selecting multicast tuning, storing PRESETS and controlling other tuner functions, as described herein.

HD LOCKED – Blue LED indicator illuminates when tuner has acquired OFDM portion of an HD Radio

signal and digital carrier SN is > 58dB/Hz, thereby permitting HD RadioTM digital audio to be

valid.

MULTICAST – Blue LED indicator illuminates when tuner has acquired OFDM of an HD Radio

signal

and there is at least one multicast signal present, i.e., HD-2 through HD-8.

DELAY SET – Blue LED indicator illuminates when tuner has acquired OFDM of an HD Radio

MPS signal and the analog diversity delay is active. The LED is off when there is no delay bit set, i.e. “ball game mode” meaning that the analog program has not been delayed to be coincident with the HD Radio

MPS signal.

TUNER ALARM – Red LED indicator identifies a detected alarm condition in any tuner module. It is solid when any alarm on the selected tuner has been enabled. When an alarm condition occurs, the tuner module’s LED flashes, the beeper beeps and the appropriate rear panel contact closes.

M3 Front Panel Layout

HEADPHONES. Headphone stereo output is via a recessed front panel mounted mini-TRS jack. Pressing and holding the MODE – SERVICE button will allow you to access the headphone output adjustment screen. The up and down buttons will adjust your headphone output accordingly. When desirable level is set, press SELECT to save your settings and exit the menu. Default set at the factory is 50mV.

M3#User#Manual#

Shared Controls and Displays

The following controls and displays are ‘shared’ among the three tuner module based on the Tuner 1, 2, 3 switch selection.

TUNER 1, 2, 3 – Selects the tuner module to receive front panel switch activity via the system processor and bus.

ALARM SETUP - A momentary push of this switch enables the alarm setup menu in the selected tuner module’s VFD. Hold this switch for 5 seconds to arm the alarms as configured in the alarm setup menu.

CLEAR ALARMS - A momentary push of this switch clears all active alarms for the selected tuner module. The Alarm LED then goes back to solid, the beeper stops and the rear panel contact opens. Hold this switch for 5 seconds to disarm the alarms as configured in the alarm setup menu.

TUNER BAND – Selects manual AM and FM tuning for the selected tuner module; tune using the dedicated UP and DN controls. Blue arrow LED illuminates when mode is active.

PRESETS – Each tuner module has capability to recall 20 stored AM stations and 20 stored FM stations – for a total of 120 stations. PRESETS control selects PRESETS mode for the selected tuner module; scroll through stored stations using the dedicated UP and DN controls. Blue arrow LED illuminates when tuner is in PRESETS mode. When in PRESETS mode, second momentary push of PRESETS switch toggles between AM and FM stored presets.

MODE - SERVICE – Momentary push activates MODE – SERVICE menu. Blue arrow LED illuminates only when switch is being pushed, or when MODE – SERVICE menu is active. In any active mode, second momentary push of MODE – SERVICE at any time clears mode. The MODE – SERVICE menu options are MODE, SERVICE and DIAGNOSTICS.

FORCING – The FORCING control is used to setup the forcing state of the selected tuner module. Blue arrow LED illuminates only when switch is being pushed, or when FORCING menu is active. The FORCING menu contains three options: Forced Analog, Forced Digital and A-D Split; options are dependent on the type of broadcast being received, i.e., HD-1, multicast HD-2 through HD-8, or analog, as described below. In any active mode, second momentary push of FORCING control at any time clears mode.

DATA - DISPLAY and DATA - DISPLAY Menu – Selects decoded RDS/RBDS from an analog FM broadcast and PSD messages from an HD Radio

broadcast for display on the second line of the VFD. Momentary push DATA - DISPLAY switch scrolls display through each RDS/RBDS and HD Radio

PSD message data field, as described below.
