2Warnings and Safety Information
THUNDERSTORM AND LIGHTNING WARNING:
DO NOT USE Tieline codecs during thunderstorms and lightning. You may suffer an injury
using aTieline codec, or any device connected to aLAN connection during athunderstorm.
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 alighting tower at asports 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 ATIELINE PRODUCT CAUSED BY LIGHTNING or an ELECTRICAL
STORM WILL VOID THE WARRANTY. Use of this product is subject to Tieline's
SOFTWARE LICENSE and WARRANTY conditions, which should be viewed at
www.tieline.com/support before using this product.
Disclaimer
Whilst every effort has been made to ensure the accuracy of this manual we are not responsible for
any errors or omissions within it. The product specifications and descriptions within this manual will
be subject to improvements and modifications over time without notice, as changes to software and
hardware are implemented.

8Adjusting Input/Meter Levels
The codec uses dBu to express nominal operating level, headroom and noise floor levels. The PPM
meters display input audio by default when the codec is not connected and they then switch to
monitor decoded return program audio after making aconnection.
Mono and Stereo Audio Capabilities
The codec sends input 1directly to the left output and input 2directly to the right output. When
sending mono analog audio select amono algorithm in the IP Connect Setup menu and connect
audio to input 1of the codec. Input audio is replicated and sent to both channel 1and 2analog XLR
outputs in this mode. The AES3 outputs are directly mapped to both the analog and digital inputs,
therefore if amono analog profile is selected, only channel one will have audio on it over AES3.
Note: It is not possible to mix channels 1and 2into dual mono outputs.
The codec will provide both analog and digital audio out at all times and this is not dependent on
whether your audio source is analog or digital. The only point to note is that when you configure a
mono analog connection the codec will only send audio on one of the AES3 outputs, but it will send
audio on both the left and right channels of the analog outputs.
Adjusting Audio Meter Reference Scale Settings
When connected to stereo sources the top PPM meter is the left channel and the bottom PPM
meter is the right channel. The codec is configured by default to automatically connect to other
Tieline codecs using the correct audio reference meter scales. The audio reference level settings in
the codec are:
Reference Setting
Description
1
Auto (default)
When connecting to aTieline codec with session data enabled
the codec will automatically adjust the reference level for G5 and
G3 codecs. When connecting to anon-Tieline codec, or aTieline
codec without session data enabled, the codec will use the
Tieline G5 setting.
2
Tieline G5
The audio reference scale is -16dBu to +22dBu
3
Tieline G3
The audio reference scale is -11dBu and +18dBu
To configure this setting manually:
1. Press the SETTINGS button.
2. Navigate to Audio and press .
3. Navigate to Ref Level and press .
4. Select the preferred setting and press .
Audio Metering when Connecting to Tieline G5 Codecs
The Tieline G5 audio reference scale displayed on the codec screen is -16dBu to +22dBu when
you connect to acodec in Tieline's Merlin, Genie or Bridge-IT IP codec families. Set audio levels so
that audio peaks average at the nominal 0vu point. This represents aprogram level of +4 dBu leaving
the codec. Audio peaks can safely reach +22 dBu without clipping, providing 18dBu of headroom
from the nominal 0vu point. The default PPM audio meter indications are as follows.
