are routed to channels 1 and 2, while the AUX [LEFT] and [RIGHT] outputs are routed

to channels 3 and 4. Note that the [VOLUME] slider does not control the level going

to the ADAT-XT. Volume control must happen via MIDI or a Pedal plugged into the

Pedal 1 jack.

When recording to ADAT-XT (or some other digital audio recorder), it must be set to

“slave” to the 48kHz clock embedded in the digital audio which the QS is sending.

This clock can be set to either 48kHz or 44.1kHz, as determined by the Clock

function (found in Global Edit Mode, Page 19). The Clock function has four settings:

Int 48kHz, Int 44.1k, Ext 48kHz and Ext 44.1k. The default setting

is Int 48kHz, which is suitable when the digital recorder is using the 48kHz

sample rate. However, if the recorder is using the 44.1kHz sample rate, the Clock

function should be set to Int 44.1k. This ensures that the QS will be in tune

with previously recorded material. See page 47 in Chapter 4: Basic Operations for

more information on the Clock parameter.

48 KHZ IN

If your ADAT system has an Alesis BRC Remote Controller, the QS’s digital clock

must be synchronized to the clock coming from the BRC. This requires that a

connection be made providing the clock signal to the QS and that the QS’s Clock

function be set to either one of its two external settings (Ext 48kHz or Ext

44.1k).

Connect a BNC-to-BNC cable (such as the Alesis BN cable) between the BRC’s 48

kHz CLOCK OUT and the QS’s [48 KHZ IN]. Set the Clock function to either Ext

48kHz if the BRC is set to 48kHz, or Ext 44.1k if the BRC is set to 44.1kHz

(“Pitched Down” to -147).

Tip: With this type of connection, the ADAT-XT tracks will remain in tune with

the QS even when the BRC’s pitch value is adjusted.
