above the MONITOR A

output jacks is in 

the –10 dB position (counterclockwise). If it is, 

turn the control up to the +4 dB position and 

then turn up the Big Knob VOLUME control. 

Now it should get louder, faster.

10.  If you have monitors connected to the STUDIO 

OUTS

, make sure the PHONES/STUDIO 

OUTS SOURCE

button on the front panel is 

out, and the STUDIO OUTS ON/OFF

button 

is ON (LED above the button is lit).

11.  Slowly turn up the STUDIO OUTS LEVEL

control on the front panel. You should begin 

to hear playback from your DAW through your 

studio monitor speakers. Adjust the STUDIO 

OUTS LEVEL control to a comfortable listening 

level. If it seems like you have to turn up the 

LEVEL control all the way to hear the studio 

monitor speakers, turn down the LEVEL control 

and check to see if the trim control

above the 

STUDIO OUTS

jacks is in the –10 dB position 

(counterclockwise). If it is, turn the control 

up to the +4 dB position and then turn up the 

LEVEL control. Now it should get louder, faster.

12.  If you have a headphone distribution amplifier 

connected to the PHONES AMP

outputs, you 

should be able to turn up the volume for each 

headphone connected to the headphone amplifi-

er and hear playback from the DAW. If it seems 

like you’re not getting enough volume from the 

headphone amplifier, turn down all the head-

phone volume controls on the headphone ampli-

fier and check to see if the +4/–10 level switch

above the PHONES AMP

output jacks 

is in the –10 dB position (pushed in). If it is, 

switch it to the +4 position and then turn up the 

headphone volume control on the headphone 

amplifier. Now it should get louder, faster.

13.  You can connect a pair of headphones to one of 

the two PHONES

jacks on the front panel of 

Big Knob. Slowly turn up its associated LEVEL

control to a comfortable listening level.

14.  If you want to record from the DAT or cassette 

player to your DAW, start playback on the DAT 

or cassette connected to Big Knob.

 

CAUTION:

 See “A Cautionary Note” on the next 

page to avoid creating a feedback loop through 

the 2-TRACK inputs and outputs.

15.  Push in the 2-TRACK A

button in the INPUT 

SOURCE SELECT section on the front panel 

and turn off the DAW MIX button. Slowly turn 

up the trim control

for the 2-TRACK A input 

until you see the meters

on the front panel 

light. Adjust the control until the meters are 

lighting the “0” LED regularly. You want the 

“+8” LED to light only occasionally, and the 

“OL” LED to not light at all.

16.  Make sure the inputs to the DAW are selected 

for recording. Start recording and the playback 

from the 2-TRACK A input to Big Knob should 

be recording in the DAW application. If it seems 

like you’re not getting enough volume from the 

2-TRACK playback, check to see if the +4/–10 

level switch

above the DAW

output jacks 

is in the –10 dB position (pushed in). If it is, 

switch it to the +4 position. This will provide a 

stronger signal to send to your DAW.
