Installation and Technical Application Guide
HNBTM Modular Digital Mixer Amplifiers for Audio and Video
SECTION 1.0 - HNB-A + HNB-B INTRODUCTION AND APPLICATIONS
The HNBTM concept:
The HNB system is flexible, easy-to-install, use, upgrade and maintain. It
is an affordable solution for any room requiring integration of audio, video
and wireless ‘Soundfield’ amplification. HNB supports a wide range of
Audio and A/V applications with built-in compatibility to laptops, desktop
computers, A/V projectors, VCR, DVD, DVR, iPOD, MP3, and micro-
phone input sources for use in teaching and training environments. The
HNB system is a common sense ‘purpose built’ solution for universities,
colleges, K-12 schools and corporate training facilities.
In addition to A/V application support, the HNB system unifies all major
emergency communications systems into a comprehensive and seamless
solution to everyday needs. HNB is simple in its design and operation
providing immediate benefit to Consultants, Contractors and End-users.
The HNBTM building blocks: A + B + C
The HNB system is based on a simple premise of ‘hang and bang’ =
Simple, Fast, Affordable, Reliable and Secure. From the ground-up
HNB starts by using the most common device found throughout all
building types in North America – the common NEMA/UL rated elec-
trical gang box. HNB takes up no space in the room, is totally secure
while using the most inexpensive and widely available mounting
option in the market. HNB is a modular ‘plug and play’ system inte-
grating the most basic media room elements of Audio (A) + Video (B)
+ Wireless (C) which interconnect via standard CAT5e UTP cable.
NOTE: Wireless HNB-C package is covered in a separate installation
manual #SAN-HNB-C. The HNB system always starts with the ‘A’
package (HNB-A) providing a 2-gang modular AUDIO system with an
Amplifier and Preamp in addition to key I/O interconnections to vital
room communication systems including; Fire and Alarm, Security, PA
and Intercom (1v-70v), Archival or Recording systems, ancillary
power amplifiers or ‘control’ audio systems.
If VIDEO is required and/or IR control is desired add the HNB-B unit.
This additional 2-gang unit provides transmission of VGA/RGB, S-
video, Composite video signals while providing a buffered VGA
Monitor output. Video transmit and receive are accomplished via a
single CAT5e UTP cable up to 150 feet to the AV Projector.
If WIRELESS ‘Soundfield’ teacher amplification or ADA assisted lis-
tening (hard of hearing) and or simultaneous 2nd language transla-
tion is important to improve the education experience for Teachers,
Students, Parents and the Community then add HNB-C. The
Wireless HNB-C can be added at anytime to HNB A or HNB A + B
depending on your room requirements. HNB-C is an RF based sys-
tem providing up to two (2) channels of transmit and two (2) channels
of receive signals to headsets, hand-held microphones, and head-
phones which can be paired to any HNB-C equipped room in less
than (30) seconds! NOTE: Wireless HNB-C package is covered in a
separate installation manual #SAN-HNB-C.

The HNB-A and HNB-B systems are capable of supporting numerous applications,
including but not limited to: ALL EDUCATION classrooms, CORPORATE
boardrooms, conference rooms, break-out areas, briefing centers, lobbies, private
offices, ENTERTAINMENT theater backstage dressing rooms, green rooms,
practice rooms, stadium skyboxes, concession stands, RETAIL stores, restaurants
and salons, HOSPITALITY rooms, CHURCH multi-use, overflow areas,
HEALTHCARE surgery or recovery, lobbies, doctors offices, administration areas
and wherever a complete communication package for audio and video with
wireless add-on capability is desirable.
HNB-A (2-gang) and HNB-B (2-gang)
may be installed into 4 or 6-gang 3.5”
DEEP electrical boxes allowing for
expansion with HNB-B and/or HNB-B
+ HNB-C (wireless). Note: 2-gang
wall plates are provided.

3.1 Plug-in Modules: Amplifier Module HB-1S
SECTION 3.0 - HNB-A + HNB-B SYSTEM COMPONENTS
3.2 Plug-in Modules: Pre-amp Module HB-2PA
Amplifier Module (HB-1S)
The HNB amplifier module HB-1S is included with HNB-A. It always plugs into
the RIGHT SLOT (J2) of HNB-A and provides high fidelity Stereo and Mono
audio (digital class-D power) to any 4- or 8-ohm speakers. The HNB amplifier
will support 70V speakers using Sansonic HNB-70V2X matching impedance
transformer unit that may be ordered separately.
Module Features:
• Robust digital class-D architecture with better than 85% efficiency.
• Dual channel 25W into 4-ohm / 12W at 8-ohm operation.
• Mono or stereo operation with full bandwidth operation 20Hz - 20kHz.
• Fits into standard 2-gang electrical box (3.5”DEEP) with Decora wall plate.
• Automatic over current and over temperature protection.
• Manual front volume controls for R+L channels.
• IR control of each channel’s volume, bass, treble, balance (See HB-IR).
• Visible active power status LED’s for each channel (Green).
• Power 24VDC/2.5A from common UL wall power supply.
Preamplifier Module (HB-2PA)
The HNB preamplifier module HB-2PA is an integrated, high fidelity audio
mixer that can be used in the LEFT SLOT of EITHER the HNB-A or the HNB-B
chassis. It provides multiple balanced line inputs at nominal 1V/600 ohm line
level (A+B+C) via phoenix, RCA and 3.5mm connections that can be selected
via IR remote control or a manual front slide switch.
Audio inputs can be shaped for greater intelligibility via front accessible con-
trols for treble, bass and volume. Inputs may be mono or stereo and are auto-
matically routed to the HB-1S amplifier SPEAKER 1 (R) + SPEAKER 2 (L)
and AUDIO LINE OUTPUT (J7) on the rear backplane. An internal audio input
connection used for audio or microphone input has a ducking control (0dB to -
50dB) which automatically ducks the ‘B’ + ‘C’ audio sources when voltage is
present.
Module Features:
• Stereo or Mono operation at full bandwidth of 20Hz - 20kHz.
• Multiple audio source inputs via common phoenix, 3.5mm, RCA terminations.
• Audio source selection via front slide switch (A+B+C).
• Fits into standard 2-gang electrical box (3.5”DEEP) with Decora wall plate.
• AM/FM ‘RF’ and audible noise suppression.
• Signal to noise at 85dB and sensitivity at -16dBu.
• Manual front volume controls for audio and microphone channels.
