• Two mic/48v/line inputs with independent adjustable gain
• Configurable on/off buttons on the inputs
• Two 6.35mm headphone outputs
• Backlit screen
• Diversity aerials
• Configurable auto answer
• Selectable output compressor
• Selectable background noise suppressor
• Micro SIM card
• Battery powered via 6 X AA batteries
• External DC power input

Multiple Networks
A 2G GSM, 3G UMTS, and 4G LTE mobile phone with features specifically for broadcast.

High Quality Audio
The HD Voice system allows 7kHz mobile calls on compatible mobile networks using 3G UMTS or 4G LTE networks.

Two Inputs
There are independent, duplicated controls for both inputs. The illuminated on air button can be configured as latching, momentary or intelligent. There is a small gain control for setting input level.

Two Headphone Outputs
There are two x 6.35mm headphone sockets with a level adjust.

Powering Option
Battery power is available from 6 x AA batteries. There is also an external DC input from 10 – 15V.

Auto Answer
The Expedition can be set to answer incoming calls automatically.

Output Compressor
An output compressor prevents any peak in the audio being sent onto the HD Voice network. HD Voice is very sensitive to peaks and the output compressor improves the quality of the audio received at the remote end.

Glensound ‘Referee’ Input Compressor
Glensound’s Referee compressor has been specially designed and updated over many years, specifically to cope with the excessive peaks often associated with excited sports commentators.

Background Noise Suppressor
HD Voice features a background noise suppressor that greatly removes unwanted background noise.

Direct Line Output
A 3 pin XLR plug provides a clean output of the remote end of the call, with it’s own adjustable level control. This makes the Expedition a portable digital hybrid for a mobile telephone.

Diversity Aerials
The Expedition has twin diversity aerials for improved reception and range when on the 4G LTE networks.

Included Accessories
Each Expedition comes with the following accessories as standard: hard plastic case, plug top power supply, shoulder strap, pair of small SMA aerials, pair of performance SMA aerials.

Glensound HD Voice – 7kHz Audio Bandwidth
Glensound HD Voice is an automatic feture available around the world on compatible mobile networks using 4G LTE or 3G UMTS. Connecting two Glensound HD Voice broadcasters mobile phones in the same country, across a compatible 4G LTE or 3G UMTS network, will give a clear 7kHz of audio bandwidth.

HD Voice Is AMR-WB (Adaptive Multi Rate Wide Band)
Also known as G.722.2. This is the algorithm more commonly known as HD Voice. It offers significant advantages for broadcasters:

• Doubles voice bandwidth over 2G GSM to 50-7000Hz (2G narrow band speech codec is 300-3400Hz)
• 12.65 kbit/s or higher coding bit-rates provide high quality wideband audio
• Gives a better lower frequency response, down to 50Hz (2G is 300 Hz), for more natural sounding voices

Glensound HD Voice Does Not Require The Data Network
With HD Voice, The Expedition connects as a voice call, not a data call.

• Bandwidth is consistent once connected. With data connections, bandwidth varies during a connection, but on a HD Voice call it does not. Once you are connected your call quality will remain consistent.
• No extra call charges. As the network sees the connection as a voice call, there are no extra charges and no data usage as part of a data charging package.
• The Expedition will still operate at 7 kHz HD Voice even in busy locations where there is little available data – HD Voice doesn’t need data!

Configurable To Operate On 2G GSM, 3G UMTS or 4G LTE
Calls can be locked to 2G, or 3G only with any calls made on HD Voice automatically dropping down to 2G when moving outside a 3G area without disconnecting the call. The Expedition also operates as a standard 2G mobile phone, and with advances in performance and noise reduction capabilities found on the Expedition, improvements in call quality can still be heard.

Accommodates A Broader Range Of Audio Frequencies
Glensound HD Voice can accommodate a wider range of audio frequencies thus improving the overall call quality. This will aid ultimate clarity in noisy environments with reduced background noise from the background noise suppressor.

A Cost Effective Upgrade
Glensound HD Voice is one of the most cost effective upgrades that can be made to improve audio quality using mobile phones. This makes the Expedition perfect as a remote live reporting or talkback tool.
