Yamaha MR1642 - Page 2

Congratulations!
Your MR-series mixing console offers the quality that has made YAMAHA a leading name in
console design, plus a wealth of features and versatile signal routing capability that makes it
ideal for a wide range of applications. The MR842, MR1242 and MR1642 offer 8, 12 and 16
input channels, respectively. The input channels can be assigned to any of four group busses,
and the group busses, in turn, can be assigned to a master stereo buss. This combination of
group and stereo busses makes the MR-series consoles ideal for use in recording and sound
production applications as well as small sound reinforcement Jobs. The channel inputs are all
electronically balanced, but will also accept unbalanced signals — both XLR and TRS phone |
jack connectors are provided for each input. The input channels feature mic/line or tape input
selection, a 20 dB input pad and input gain control that permit precise level matching with all
types of input source. Each channel also offers a three-band equalizer with shelving low and
high bands, and a sweepable peaking mid frequency band. An insert patch point is provided
immediately prior to the EQ stage. Three auxiliary send controls on each input module
provide a range of submixes for effects, monitoring or other applications. A selector assigns
AUX 3 send to the pre-EQ channel signal or the channel’s tape input. Group assign switches
assign the channel signal to groups 1 and 2 and/or 3 and 4, with panning capability between
groups. The four group modules include the three master AUX send controls and dual AUX
return level controls with assignment switches for the four groups and the master stereo buss.
Each group module also has a pan control that pans the signal from that group across the
stereo buss. The L and R channel stereo modules include the monitor assign switches and
talkback facilities. All group and stereo outputs offer both electronically balanced +4 dB
outputs and standard -10 dB RCA pin jack outputs for compatibility with the broadest
possible range of equipment.
In order to make the most of your MR-series mixing console and all the features and versatil-
ity it offers, we urge you to read this operation manual thoroughly — and keep it in a safe
place for later reference.
