WARNING FOR YOUR PROTECTION
READ THE FOLLOWING:
KEEP THESE INSTRUCTIONS
HEED ALL WARNINGS
FOLLOW ALL INSTRUCTIONS
THE APPARATUS SHALL NOT BE EXPOSED TO DRIPPING OR SPLASHING
LIQUID AND NO OBJECT FILLED WITH LIQUID, SUCH AS VASES, SHALL
BE PLACED ON THE APPARATUS
CLEAN ONLY WITH A DRY CLOTH.
DO NOT BLOCK ANY OF THE VENTILATION OPENINGS. INSTALL IN
ACCORDANCE WITH THE MANUFACTURER’S INSTRUCTIONS.
DO NOT INSTALL NEAR ANY HEAT SOURCES SUCH AS RADIATORS, HEAT
REGISTERS, STOVES, OR OTHER APPARATUS (INCLUDING AMPLIFIERS)
THAT PRODUCE HEAT.
ONLY USE ATTACHMENTS/ACCESSORIES SPECIFIED BY THE MANU-
FACTURER.
UNPLUG THIS APPARATUS DURING LIGHTNING STORMS OR WHEN
UNUSED FOR LONG PERIODS OF TIME.
Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades with one wider than the other. A grounding
type plug has two blades and a third grounding prong. The wide blade or
third prong are provided for your safety. If the provided plug does not fit your
outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
apparatus.
Use only with the cart stand, tripod bracket, or table specified by the
manufacture, or sold with the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to avoid injury from tip-over.
Refer all servicing to qualified service personnel. Servicing is required when
the apparatus has been damaged in any way, such as power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
POWER ON/OFF SWITCH: For products provided with a power switch, the
power switch DOES NOT break the connection from the mains.
MAINS DISCONNECT: The plug shall remain readily operable. For rack-
mount or installation where plug is not accessible, an all-pole mains switch
with a contact separation of at least 3 mm in each pole shall be incorporated
into the electrical installation of the rack or building.
FOR UNITS EQUIPPED WITH EXTERNALLY ACCESSIBLE FUSE RECEPTACLE:
Replace fuse with same type and rating only.
MULTIPLE-INPUT VOLTAGE: This equipment may require the use of a differ-
ent line cord, attachment plug, or both, depending on the available power
source at installation. Connect this equipment only to the power source
indicated on the equipment rear panel. To reduce the risk of fire or electric
shock, refer servicing to qualified service personnel or equivalent.
If connected to a 240V supply, a suitable CSA/UL certified power cord
shall be used for this supply.
POWER ADAPTER: Ensure a minimum of 8 inches of clearance and ventila-
tion around the adapter.
The symbols shown above are internationally accepted symbols that
warn of potential hazards with electrical products. The lightning
flash with arrowpoint in an equilateral triangle means that there are
dangerous voltages present within the unit. The exclamation point in
an equilateral triangle indicates that it is necessary for the user to refer
to the owner’s manual.
These symbols warn that there are no user serviceable parts inside the
unit. Do not open the unit. Do not attempt to service the unit yourself.
Refer all servicing to qualified personnel. Opening the chassis for any
reason will void the manufacturer’s warranty. Do not get the unit wet. If
liquid is spilled on the unit, shut it off immediately and take it to a dealer
for service. Disconnect the unit during storms to prevent damage.

SAFETY INSTRUCTIONS
NOTICE FOR CUSTOMERS IF YOUR UNIT IS EQUIPPED WITH A POWER CORD.
WARNING: THIS APPLIANCE SHALL BE CONNECTED TO A MAINS SOCKET OUTLET
WITH A PROTECTIVE EARTHING CONNECTION.
The cores in the mains lead are coloured in accordance with the following code:
GREEN and YELLOW - Earth BLUE - Neutral BROWN - Live
As colours of the cores in the mains lead of this appliance may not correspond
with the coloured markings identifying the terminals in your plug, proceed
as follows:
•The core which is coloured green and yellow must be connected to the terminal
in the plug marked with the letter E, or with the earth symbol, or coloured
green, or green and yellow.
•The core which is coloured blue must be connected to the terminal marked
N or coloured black.
•The core which is coloured brown must be connected to the terminal marked
L or coloured red.
This equipment may require the use of a different line cord, attachment plug,
or both, depending on the available power source at installation. If the attach-
ment plug needs to be changed, refer servicing to qualified service personnel
who should refer to the table below. The green/yellow wire shall be connected
directly to the units chassis.

WARNING: If the ground is defeated, certain fault conditions in the unit or in the
system to which it is connected can result in full line voltage between chassis
and earth ground. Severe injury or death can then result if the chassis and earth
ground are touched simultaneously.

A molded mains plug that has been cut off
from the cord is unsafe. Discard the mains
plug at a suitable disposal facility.
NEVER UNDER ANY CIRCUM-
STANCES SHOULD YOU INSERT A

Operating Instructions
Overview
The BSS Audio BLU-HIF Telephone Headset Interface facilitates connection of the
headset jack of a VoIP/digital phone to an AEC input and analog output of a Soundweb
London device. The BLU-HIF therefore allows the VoIP/digital phone to be used as the
dialing interface and hybrid for a conference system. This simple interface eliminates the
programming requirements associated with third-party control systems, while providing a
familiar and low-cost dialing interface to the end user.
Connections
Audio Tx
This balanced connection is for sending near-side audio. Connect it to a standard analog
output of a Soundweb London device. See Figures 1 and 2 for system connection and
DSP conguration diagrams.
Audio Rx
This balanced connection is for receiving far-side audio. Connect it to an AEC input
on a Soundweb London device. See Figures 1 and 2 for system connection and DSP
conguration diagrams. While the BLU-HIF provides substantial isolation of the Rx and Tx
signals, near-side audio will still be heard on the Rx channel due to the presence of side-
tone. As such, BSS Audio recommends always feeding the Rx channel to an AEC input, as
opposed to a standard analog input. The AEC algorithm will remove the side-tone.
The Audio Tx and Rx connections are via Klippon pluggable terminal block connectors
(also known as BL, Phoenix or Combicon). 6-way female Klippon connectors are supplied
for making these connections.
Soundweb products provide cable shielding ‘back from the destination’ to eliminate
ground loop problems. This means that the shield (S) connection on an input is grounded,
whereas the shield connection on an output is oating (although connected via an
internal network to ground for EMC compliance).

Telephone Headset – RJ-22 Jack
The BLU-HIF features an RJ-22 jack for connection to the headset jack of a VoIP/digital
phone. See Figure 1 for a system connection diagram using the telephone headset RJ-22
jack. The wiring conguration within the headset jack of a VoIP/digital phone often differs,
depending on the manufacturer. The BLU-HIF comes with two cables whose 4P4C RJ-22
connectors are compatible with the two most common wiring congurations found in the
headset jack of VoIP/digital phones. See Figure 3 for the BLU-HIF internal wiring diagram.
Caution: before connecting to the RJ-22 jack, ensure that the internal jumper is set to
the appropriate position. Do not connect to both Telephone Headset jacks (RJ-22 and
2.5mm) on the BLU-HIF simultaneously. Doing so risks damaging the connected devices.
By default, the BLU-HIF ships with the jumper set to the Telephone Headset RJ-22 jack
position. See Figure 5 for an internal jumper conguration diagram.

Telephone Headset – 2.5mm Jack
The additional 2.5mm jack facilitates connection of two-way communication devices
such as cellular phones to a Soundweb London device. This gives the end user the
advantage of having an alternate communication path to the outside world, which is
particularly useful as a backup to the main phone system. See Figure 3 for the BLU-HIF
internal wiring diagram.
Caution: Before connecting to the 2.5mm jack, ensure that the internal jumper is set to
the appropriate position. Do not connect to both Telephone Headset jacks (RJ-22 and
2.5mm) on the BLU-HIF simultaneously. Doing so risks damaging the connected devices.
By default, the BLU-HIF ships with the jumper set to the Telephone Headset RJ-22 jack
position. See Figure 5 for an internal jumper conguration diagram.
