allows signals to go up to +22dBu. In mastering, it is important to be able to modulate the
A/D to full scale without slew rate distortion so the maximum level has migrated to
+18dBu in many mastering houses. We put a switch on the back of
MQ
so that either
system could be accommodated without overloading (pinning) the meters. Mastering
compressed material may require the offset even with the maximum system level set to
+18dBu.
Talkback Dim
: There are individual jumpers on the headphone amplifiers that enable the
“cue dim on talkback activation” function. The jumpers can be lifted to provide what is
known as “conductor’s talkback” where communication with the artist happens without
dimming the music feed.
Input shield lifts/chassis isolation
: These jumpers can correct a buzz or hum problem
with unbalanced sources that don’t have a ground reference by connecting the audio
ground to the input cable shield. If a buzz is encountered with an individual input, change
the jumper setting of that input. This will almost always clear up the problem. The
chassis lift jumper is provided if MQ is bolted in a rack with electrically noisy devices
(light dimmer packs for instance) that cause interference. It is not recommended to lift the
ground on AC plugs of equipment to cure ground buzzes. An in depth treatise of this
subject is available in the Monitor manual at dangerousmusic.com.
This is a view of the MQ main board, connectors towards the reader.
