1.0 Introduction
CL and QL-series Version 3 firmware introduces Surround Sound features for 5.1
panning and monitoring. As a part of the feature set, a sophisticated external
Surround Metering device can be connected to the mixing console. Some GPI
control can be setup from the User Defined keys. The TouchMonitor TM7 unit from
RTW is the Surround Metering device used in this setup guide. The RTW TM9 will
also work in a similar way. These units support useful features such as EBU R 128
Loudness metering, a Surround Sound Analyzer, audio Vectorscopes, and BLITS 5.1
test signals. This guide provides a step-by-step solution for connecting the TM7 with
a Yamaha CL or QL digital mixing console. For other device functions, the product
manuals or help files should be referred to.
2.0 Preparing the cables
2.1 Audio Connection
The Surround Metering device should be
connected to one of the console’s optional
“MY” slots, and the correct card should be
chosen to match the rear panel
configuration of the TM7 unit. There are
three choices:
1. If the TM7 has the HW20711 audio
interface installed, with 4x AES3
inputs on a 25-pin D-sub connection,
then a Yamaha card such as MY8-
AE96 or MY16-AE should be
installed in the console. See below for the pin configuration table, because
both devices do not share the same layout. A custom 110Ω multi-pin cable
should be created.
2. If the TM7 has the HW20712 audio interface installed, with 4x AES3id
connections, then a Yamaha MY8-AEB card should be installed in the console.
4x 75Ω BNC cables will be required.
3. If the TM7 has the HW20714 audio interface installed, with a 3G-SDI
connection, then a Yamaha MY8-SDI-ED must be installed in the console. 1x
75Ω BNC cable will be required.
