Introduction

DaySequerra’s M4FM-HD is the most powerful and cost-effective FM analog radio modulation monitor
available today. Using a state-of-the-art Texas Instruments® DSP running at 350 MHz, all of the M4FM­HD processing takes place in the digital domain.

The M4FM-HD’s Texas Instruments® DSP provides superb analog audio performance (SNR > 75 dB
and THD < 0.1%) as well as simultaneous total, pilot, L, R, L+R and L-R, and all Composite-SCA
modulation level measurements with better than 1.0% accuracy. The M4FM-HD also provides decoded
RDS/RBDS data.

In addition to its accuracy and features, the M4FM-HD gives you audiophile grade Class-A biased
audio outputs at +4 dBm on XLR connectors, so you can monitor and adjust your processing. In
addition to L and R analog outputs, the M4FM-HD has a full-time AES-3 digital audio output, so you can
feed your AES monitoring chain, and a high-performance headphone output with greater than 1W into
8-ohm for an uncompromised, convenient audio monitor.

The M4FM-HD rear panel has an FM composite output, as well as a GPIO port that provides opto­isolated reset input and relay-contact closure alarm outputs for loss of audio, carrier and RBDS. You
can control and monitor the M4FM-HD from anywhere in your plant via the M4FM-HD’s integrated
webserver, which is fully compatible with most web browsers and operating systems. The M4FM-HD’s
Remote Dashboard provides complete remote control monitoring, 50 station scanning, logging and
alarm status; it delivers simultaneous total, pilot, L, R, L+R and L-R, all MPX-SCA modulation level
measurements and decoded RDS/RBDS data. The M4FM-HD will send alerts to your phone; and you
can reset the M4FM-HD remotely as well.

Your M4FM-HD is HD Radio ReadyTM meaning it can be fully upgraded at any time to provide complete
HD Radio® capability. With our Factory-Direct Upgrade program, you can be sure that your investment
in a DaySequerra M4FM-HD will continue to pay off well into the future.

Status

• Alarms – Bi-colored LED: Green indicates that an alarm is set. Red LED illuminates when an
alarm is active. Red will flash every second when an alarm conditions are met until either the
user disables the alarm or the conditions move outside of the set parameters.

• HD Locked – Blue LED illuminates when tuner has acquired OFDM (orthogonal frequency
division multiplexing) portion of an HD Radium signal and digital carrier S/N > 58dB/Hz, thereby
permitting HD Radium digital audio to be valid. HD is displayed in upper right hand corner of
VFD when tuner has acquired OFDM portion of an HD Radium signal.

• Multicast – Blue LED illuminates when tuner has acquired OFDM of an RadioTM signal and
there is at least one multicast signal present.

• RF Level – Bi-colored LED: Green indicates strong RF > 40 dB. Red indicates weak RF < 40
dB.

• Up Arrow – Momentary push UP from the Homescreen will enter the Headphone volume menu.
Both arrows are used to increase and decrease the volume. From selection mode Press
ENTER again to change a value in any a field indicating a blinking arrow ready. Use the UP
and DOWN arrows to navigate/toggle through the available choices or range. UP Arrow button
tunes the frequency up one increment while tuning to a new station, when held for three
seconds it tunes faster at 1.5x speed. 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. Holding the UP arrow while powering the unit on will restore
factory settings.
