The MICRON Heritage
Micron wireless microphone and communication systems have been setting
industry standards in broadcast and location
recording for some four decades. The company's
design focus is on applying sophisticated
electronic engineering to achieve the optimum
balance of performance and cost. The Explorer
Series combines the legendary Micron qualities of sonic
integrity, long-term reliability and rock-solid construction
at a new and
highly affordable
price point.
Real World
Survivability
Micron Explorer transmitters and
receivers are manufactured from a highstrength
yet lightweight one-piece
aluminium extrusion with a rugged
anodised finish. They feature high-quality
connectors, with a unique design of
battery compartment that is simple to
operate by feel alone, and accepts
commonly available alkaline batteries.
Matching performance to budget as
competitively as possible, Explorer
Series products offer RF bandwidths up
to 32MHz wide, and are switchable
across 100 frequencies - maximising
operational flexibility for
personal single camera
operators, sound
recordists and
ENG teams.
Flexible Transmission
• Mic or line level input, with audio modulation indicator
• Battery level indicator
• +ve and -ve bias for electret microphones
• External powering (+12 to +16V) with TP series leads
• Powering for a wide range of 'Phantom' and 'T' condenser mics
• Professional, long-life connectors for audio input and antenna
EXPLORER TX700-A Pocket Transmitter
The Explorer's sophisticated design acknowledges our over-crowded
spectrum, and the non-harmonised radio microphone allocations of several
territories. The choice of one hundred frequencies, combined with the
broad system bandwidth, ensures high levels of frequency agility, with the
TX700-A designed to provide the highest possible quality of transmitted
signal.
This approach achieves the utmost flexibility in operation for crews, operators
and recordists, whether working internationally or simply under circumstances
prone to interference, and offers the freedom and convenience of being able
to use the systems across the world.

Preserving audio signal integrity is also a priority. The TX700-A offers easy
adjustment of the audio input level via a secure top-panel control, with a
peak-reading LED level indicator. Designed to handle very high input levels,
with generous headroom, the TX700-A includes a fast-response limiter with a
soft curve that is set up specifically to avoid clipping the signal on peaks.
Also acting as an automatic gain control, but free of the pumping effects
usually associated with this type of circuit, the limiter enables operation with
lower-budget camcorders or mixers.
Dedicated audio input cables are available to connect mic or line level
signals to the transmitter, and to power a variety of microphone types, such
as T-powering low-voltage condensers and P48 phantom-powered designs.
Equipped with a battery-status LED indicator, the TX700-A can be powered
by alkaline or lithium ion batteries, with the unique battery compartment
enabling quick and simple battery replacement. The battery compartment's
design, together with the Explorer's overall strength and durability, is focused
on withstanding the heavy demands of location use.
EXPLORER SR550 Small Receiver
Designed to operate with the new generation of DV camcorders, the
SR550 is an ultra-compact receiver, available at an extremely modest cost.
Useful in situations where receiver size and weight are important, the
SR550 maintains absolute integrity in terms of overall quality, performance
and reliability, and is small and light enough for easy mounting on
camcorders.
The SR550 offers 100 switchable frequencies across a 32MHz or 24MHz
bandwidth, depending on regional or national requirements, to avoid
interference from local RF sources and to provide maximum flexibility for
location and outside broadcast.
Offering excellent standards of RF performance, the SR550 features multiple
RF stages to give outstanding sensitivity and selectivity, while the digitally
controlled circuitry achieves optimum mobile operation. The receiver's
unique noise reduction system provides trouble-free operation in low RF
signal situations, and even in hostile RF environments.
Audio output level is controlled by a three-position switch, to match the input
signal requirements of camcorders, mixers and ancillary systems. Two 3colour
LED displays on the top panel provide continuous information on
received signal strength and battery condition. A secure on-off switch is also
provided on the top panel.
Powering can be from an internal battery, or from an external source via the
multipin input connector using optional adapter cables. Featuring the same
battery compartment design and case construction as the TX700-A, the
receiver represents a high-quality product, engineered for reliable long-term
operation.
