2 Warnings and Safety Information
THUNDERSTORM AND LIGHTNING WARNING:
DO NOT USE Tieline codecs during thunderstorms and lightning. You may suffer an injury
using a Tieline codec, or any device connected to a LAN connection during a
thunderstorm. This can lead to personal injury and in extreme cases may be fatal.
Protective devices can be fitted to lines, however, due to the extremely high voltages and
energy levels involved in lightning strikes, these devices may not offer protection to users,
the Tieline codec and equipment connected to the codec.
Secondary strikes can occur. These secondary strikes are induced by lightning strikes and
also produce dangerously high currents and energy levels. You only need to be near an
object struck by lightning to lead to personal injury or damage to equipment. e.g. if located
near a lighting tower at a sports facility, water features and drains on golf courses you may
be affected by these secondary strikes.
Damage to personnel and Tieline codecs may occur during thunderstorm, even if the
codec is turned off but is connected to the system or the power.
ANY DAMAGE TO A TIELINE PRODUCT CAUSED BY LIGHTNING or an ELECTRICAL
STORM WILL VOID THE WARRANTY. Use of this product is subject to Tieline's

8 Adjusting Input/Meter Levels
By default, the PPM METERS on the front of the codec, or in the HTML5 Toolbox Web-GUI, use
dBFS to express nominal operating, headroom and noise floor levels. The PPM meters display
input audio by default when the codec is not connected and then switch to monitor decoded return
program audio after making a connection.
Mono and Stereo Audio Capabilities
The codec routes input 1 directly to the left output and input 2 directly to the right output when it is
not connected.
To connect in stereo select a stereo algorithm in the IP Setup menu via Connect > IP > Tieline >
Setup. To connect in mono select a mono algorithm in the IP Setup menu. In mono the codec
mixes both inputs 1 and 2 together.
When a Bridge-IT codec answers a mono incoming call it feeds mono audio to both the left and
right analog XLR outputs, as well as the left and right AES3 outputs. Note: It is not possible to mix
channels 1 and 2 into dual mono outputs.
The codec feeds both analog and digital AES audio out at all times, whether the audio source is
analog or digital.
Adjusting Audio Meter Reference Scale Settings
The codec can also automatically adapt to different Tieline reference scales. A Tieline codec with
proprietary Tieline session data enabled will automatically adjust the reference level to suit G5 and
G3 codecs, or Report-IT, using the default Auto reference level setting. When connecting to a
non-Tieline codec, or a Tieline codec without session data enabled, the codec will use the Tieline
G5 reference scale setting.
The default Tieline G5 audio reference scale displayed on the PPMs when you connect to a
Tieline G5 codec is -38dBFS to 0dBFS (e.g. Merlin, Genie, Bridge-IT and ViA codec families).
Using this reference scale audio peaks can safely reach 0dBFS without clipping, providing 18dB of
headroom from the nominal 0vu point.

Bridge-IT, Genie, Merlin and ViA codecs have more audio headroom than Tieline G3 audio
codecs (Commander and i-Mix G3) and Tieline's Report-IT app, therefore the audio metering
reference scale needs to be adjusted when connecting to one of these products. The comparison

Configure Tieline G3 Codec Audio Reference Scales
Genie, Merlin, Bridge-IT and ViA codecs have more audio headroom than Tieline G3 audio
codecs, therefore the audio metering reference scale needs to be adjusted when these codecs
connect to a Commander or i-Mix G3 codec. The G3 metering scale is between -29dBFS and
0dBFS and audio levels should average around the nominal 0vu point at -14dBFS. Audio peaks
should not exceed 0dBFS when using analog audio to prevent clipping.
1. Press the SETTINGS button.
2. Navigate to Audio and press .
3. Navigate to Ref Level and press .
4. Select Tieline G3 and press .
Important Note: If your codec (Genie STL, Genie Distribution and Bridge-IT) supports
sending multi-unicast connections and the Auto (default) reference level is selected, the
first codec to which you connect configures the reference level used for all subsequent
multi-unicast connections.
Configure Report-IT Audio Reference Scales
The Report-IT setting is used for compatibility when connecting using Tieline's Report-IT
smartphone application. The Report-IT metering scale is between -23dBFS and 0dBFS and audio
levels should average around the nominal 0vu point at -10dBFS. Audio peaks should not exceed
0dBFS when using analog audio to prevent clipping.
1. Press the SETTINGS button.
2. Navigate to Audio and press .
3. Navigate to Ref Level and press .
4. Select Report-IT and press .
Channel 1 Mic/Line Level Audio Adjustment
The default input level setting in the codec for channel 1 is line level. To adjust this setting for a
mic-level or unbalanced source:
1. Press the SETTINGS button.
2. Navigate to Audio and press .
3. Ensure Input Type is set to Analog.
