Introduction

The DaySequerra M2 HD Radio
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 Radio
stereo separation >90dB for HD Radio

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 Radio

TM

and SPS multicast signals.

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 Torx
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.
