H. LINE INPUT. XLR For balanced or unbalanced +4 line level sources. Transformer coupled. The PIN-OUT
is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
I. PREAMP OUT (PHONE JACK). The signal from the mic preamplier and compressor before the trans-
former. It is designed to be the cleanest output for direct to tape recording. The output phone jacks are different
from the inputs. The phone jack outputs can only be unbalanced and are designed to bypass the output trans-
formers. Some people don’t like transformers. One of our favorite studio owners sez “I hate the sound of bad
transformers and love the sound of good ones”. These are great transformers and have very little color. You can
verify this by comparing the phone and XLR output one at a time. At “worst” the XLR outputs seem to have
slightly more bottom and punch. When you insert a phone plug it cancels the XLR output because it removes
the transformer right out of the circuit. This unbalanced output is coupled with a MULTICAP for you audio-
philes out there. It will be ne driving balanced inputs as well as unbalanced inputs and is designed for pro +4
dBu nominal levels The PIN-OUT is:
TIP = SIGNAL
SLEEVE = GROUND
and if you must use stereo plugs connect the RING to SLEEVE and/or if you are sending to a balanced input
connect LOW or negative to the SLEEVE at either end.
J. PREAMP OUT (XLR): A transformer balanced version of the mic preamplier and compressor output. Note
that a 1/4 inch phone plug in the jack below will kill this output. The PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
K. INSERT INPUT (PHONE JACK): Like the LINE IN can be used balanced or unbalanced. This input only
goes to the EQ section. It is intended as a return for a noise gate or other processor between the mic pre and
EQ. It is also a way to bring in a second input to use the VOXBOX for two separate tracks. The PIN-
OUT is the same as the LINE INPUT and the same electronically.
BALANCED - (using a stereo phone plug ) UNBALANCED - (using a mono or stereo plug)
TIP = HOT = positive + TIP = SIGNAL
RING = LOW = negative - (RING = GROUND = SHIELD)
SLEEVE = GROUND = SHIELD SLEEVE = GROUND = SHIELD
L. INSERT INPUT (XLR): For balanced or unbalanced +4 line level sources. Transformer coupled XLR. The
PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
M. EQ OUT (PHONE JACK). The signal from the EQ and De-Esser before the transformer. The phone jack
outputs can only be unbalanced and are designed to bypass the output transformers. When you insert a phone
plug it cancels the XLR output because it removes the transformer right out of the circuit. This output is also
coupled with a MULTICAP. It will be ne driving balanced inputs as well as unbalanced inputs and is de-
signed for pro +4 dBu nominal levels The PIN-OUT is:
TIP = SIGNAL
SLEEVE = GROUND
and if you must use stereo plugs connect the RING to SLEEVE and/or if you are sending to a balanced input
connect LOW or negative to the SLEEVE.
N. EQ OUT (XLR): A transformer balanced version of “M”. This is also the nal output or main output. Note
that a 1/4 inch phone plug in the jack below will kill this output. The PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
