Introduction
The DaySequerra M2 HD RadioTM Modulation Monitor is one of the finest broadcast modulation monitors available with built-in multicast capability. The M2 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 RadioTM AM and FM broadcast signals (THD+N <.005% with stereo separation >90dB for HD RadioTM FM signals).
The DaySequerra M2’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 RadioTM programs, including display of program applicable data (PAD) for MPS and SPS multicast signals.
Its robust, modular architecture ensures that the M2 will never become obsolete. The rugged M2 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 RadioTM services and programming. This design approach along with our Factory Product Upgrade program ensures that your investment in a DaySequerra product will continue to pay off well into the future. Visit www.daysequerra.com for details including the addition of a PLM option to your M2.0X or upgrading to a fully-featured M2.2R.
Please read this manual thoroughly before operating your M2.

Unpacking and Installing the M2
Immediately upon receiving your M2, 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 M2 is shipped in one carton, which contains: the M2 unit, an AC power cable, a TorxTM T-8 L-key and this User Manual.
We strongly encourage you to save the shipping carton and shipping materials supplied with your M2. They are specially designed to properly protect your M2, 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 contact you when software updates become available. 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 M2 chassis has four rack mounting holes in its chassis and has been designed to fit in a 19” standard 1RU space. Plastic ‘finishing’ washers are recommended to protect the painted finish around the mounting holes.
Power Connection. The AC power cable supplied with the M2 must be connected from the M2’s IEC320 power entry module to an AC mains outlet with a functional earth ground connection. The M2 has been set at the factory to operate at 120VAC unless otherwise specified on the shipping carton.
Please connect your M2 to an uninterruptible power supply (UPS) to protect against power surges and brownouts.
Antenna Input Connections. Separate 75ohm F-type connectors are provided on the M2 rear panel for dedicated AM and FM antennas. Rear panel switch selects for antenna or high-level (7VP-P) inputs.
Audio Output Connections. Analog audio left and right outputs are on rear-panel XLR connectors with pin 1 GND, pin 2 + and pin 3 -. The digital audio output is transformer-isolated in S/PDIF format on a rear-panel XLR connector with pin 1 GND, pin 2 XFMR and pin 3 XFMR. The M2 digital audio output is 5.1 surround capable.
Front Panel Controls and Indicators
TUNER BAND – Selects manual AM and FM tuning with UP and DN controls. Blue arrow LED illuminates when mode is active. See below for multicast tuning.
PRESETS – The M2 has capability to recall 20 preset or stored AM stations and 20 preset or stored FM stations. Blue arrow LED illuminates when monitor is in PRESETS mode. UP and DN controls scroll through stored stations. When in PRESETS mode, second push of PRESETS switch changes tuner band.
UP and DN – For manual AM and FM tuning in TUNER BAND mode and scrolling through PRESETS in PRESETS mode.
SELECT – Multi-function switch for storing PRESETS and controlling other monitor functions, as described below.
