TV Connections
Connecting Directly to a Television
If connecting directly to a TV set via optical then you must make sure
that the TV is set to PCM. To do this go into the audio/sound settings
menu on the TV and look for digital audio output/optical out, normally
this would be set to Dolby digital, it needs to be changed to PCM.
Please note that some Televisions auto switch this setting!
NOTE: Using the microphone supplied with your equipment attached
to the speaker grille of the television will return good results and is an
excellent back-up way to connect to the TV.
Setting up your equipment with direct connection to
Sky Q & Sky HD Boxes via Optical
• Press Home on your Sky Q remote, select Settings, then select
Setup
• Select Audio visual, then select Digital audio output optical and set
it to NORMAL
• Press the GREEN button to save the settings
• Power OFF the Sky Box, leave for 30 seconds and turn back on,
leave for 5 minutes until the box has had chance to re-calibrate
itself and then test the system
Setting up equipment with direct connection to Virgin
Media Set Top Boxes via Optical
• Press Home on your remote
• Select Help & Settings

8
• Select Settings
• Select Audio
• Choose Dolby Digital to PCM. This setting applies to both HDMI
and optical out.
• Power down the box for 5 minutes, restart the box, leave for a few
minutes and test the
system
• Virgin Media 360 Boxes ONLY: Select Settings > Audio & Video >
Follow Content > Restart Box
Why don’t I get audio from digital sources (Netflix,
Apple TV, FireStick, etc)?
Audio coming from certain content providers or devices (Netix,
Amazon Prime, Apple TV etc.) is by default set to output Dolby and not
PCM.
In order to resolve this, you will need to change the digital audio
output format in the app or device to PCM, rstly try the normal audio
settings within the app, however very often these audio settings are
only available once something is playing on screen.
This does NOT guarantee that you will hear the audio from these
sources through your device, but it does give the best chance.
N.B when connecting directly to an external device such as SKY or
Virgin Media you will not hear channels and smart services from the
TV through the connected equipment.

Setup Instructions
HLD4 Hearing Loop Driver
1. Place the driver in a convenient and well ventilated area near to
the TV or other audio source. Ensure all necessary connection
leads can reach the relevant device.
Option 1:
Installing the Hearing Loop Cable
1. Run the loop cable around the room starting
and ending at the hearing loop driver. The
cable may be tucked under the edge of the
carpet, or xed to either a picture / dado rail
or skirting board with the clips provided.
2. Where the cable passes a door or other obstacle, ideally tuck it
under the carpet or x the cable around the frame if tucking under
the carpet isn’t possible. For best performance the cable should
stay on the same plane.
3. The cable only has to go around the area to be looped.
• Excess loop wire may be cut off, provided a MINIMUM of 11 metres
(35 feet) is left connected to the hearing loop driver. DO NOT leave
spare cable coiled on the drum.
Option 2:
Installing the Hearing Loop Pad
1. Place the loop pad in a suitable
position on the chair to be used for
listening, either on the chair back or
under the seating area.
2. Lay the connecting lead from the Pad
