HUM Audio Devices ARM-1 was designed, developed and precisely handcrafted in
Poland.
Introduction
ARM-1L and ARM-1S are active mono ribbon microphones, that inherit build
and sound quality from our flagship stereo RS-2 Ribbon Recording System. Custom
tailored 1.8 micron aluminium foil ribbon motors are paired together with
audiophile quality handcrafted audio circuit and high precision CNC-machined
mechanics.
There are two mechanically similar models with distinct sound that will let
you choose appropriate mic for your application: ARM-1L (with blue suspension
orings) has the same 2 inch ribbon motor like our flagship RS-2 microphone and
little more „character” in sound, while ARM-1S (with white suspension orings) is
equiped with 1 inch ribbon motor and has more clean and neutral sound.
You will find that both ARM-1 models excel on many sound sources, covering
wide range of studio recording applications, including string section recordings,
piano, guitars, woodwinds, ambience, drum overheads and vocals. They will give
you precious classic, huge, larger than life sound with a lot of details typically

found in good condenser mics, but at the same time you have that classic lovely
ribbon sound flavour, so much beloved by musicians and sound engineers. Tracks
recorded with ARM-1 mics also blend very well with other elements in the mix.
That's a distinctive feature of all best mics on the market.
Operation Safety
Do not use this devices anywhere near water (for example in a bath room, a
damp cellar, near swimming pools, or similar environments). Otherwise your are
dealing with risk of mic damage. ARM-1 should also not be installed near equipment
which produce strong magnetic fields or extreme heat.
Be careful to not insert any object into any of the mic chassis openings. You can
otherwise taking the risk of ribbon motor damage. Never allow any fluids to be
spilled or sprayed on the ARM-1 body. Such actions can lead to ribbon damage or
short circuit in mic's signal patch!
Ribbon mics are very sensitive to air flow blowing
directly onto motors foil. In case you plan to
record sound sources that can emit blasts of air,
like vocal, woodwind, kick drum or guitar combo –
place ARM-1's mic head off axis of air flow source
and consider using a pop filter, otherwise you can
damage the motor !
Service and Repairs
Turn off the Phantom power on your preamp, unplug the ARM-1 mic from
preamp and contact your local dealer when you think repairs are needed – or when
moisture or foreign objects may accidentally have reached inside ARM-1 mic
housing, or in cases when the mic may have fallen and shows any sign of having
been damaged. This also applies to any situation in which the unit have not been
subjected to any of these unusual circumstances but still is not functioning
normally or its performance is substantially altered. All repairs are done at HUM
audio Devices factory or in some cases at authorized dealer's site.

Do not open any of ARM-1 mics yourself -
– there are no user serviceable parts inside !
Replacement parts
Be sure that any authorized service technician uses original replacement parts
or those with identical specifications as the originals. Incorrectly substituted parts
can lead to fire, electrical shock or other dangers, including further equipment
damage. HUM Audio Devices can only guarantee quality of performance if correct
replacement parts are used.
Always be sure to ask a service technician to conduct a thorough safety check
and ensure that the state of the repaired device is in all respects up to factory
standards.
leaning
Do not use any solvents or liquids, as these can damage the chassis, rubbers or
inscriptions. Use a clean, dry cloth. Great for cleaning ARM-1's anodised mic body
is dry microfibre cloth. Disconnect the device from Phantom power source before
cleaning.
Declaration of E onformity
The construction of these units is in compliance with the standards and
regulations of the European Community.

Using ARM-1L and ARM-1S microphones
To use ARM-1 mics connect them to mic preamplifier with +48V Phantom
power. Because both mics are built to have top-notch sound, we strongly
recommend using them with as good preamps as possible, that will extract and
preserve all subtle details from recorded sound.
Especially we recommend our RP-2 Remote Controlled Discrete Class A Mic
Preamp, to create perfect and very versatile set. That will give you strong benefits,
because ribbon mics are very sensitive to preamp quality and also to quality and
length of audio cables. Putting RP-2 Preamp Box near your ARM-1 microphone will
give you an advantage of short signal path. Also RP-2's high-end circuits are
precisely tailored to give you the best sound you wish to have from ribbon mic.
ARM-1 mics will not operate without Phantom power switched on!

On bottom of ARM-1 microphone you will find switch that will let you
choose High Pass Filter between 50 Hz and 100 Hz. This is gentle 6db/oct slope
passive filter that sounds musical and will lower excessive subsonics from mic if
necessary.
Hand Lever operation
ARM-1 microphone swivel has a special rotatable hand lever with built-in
spring mechanism. Together with locking clutch action it provides fast and
convenient change of microphone angle position.
Thanks to the spring mechanism you can tighten or loose the lever fully even
when only small rotation angle is possible. To make full use of this feature - just
pull the lever towards the grey arrow , rotate to a new required starting position
(black arrow) and release. Then you can continue to tighten or loose the lever.
