PECIFICATIONS

All measurements taken with an Audio Precision System One. All noise
measurements taken with trim at minimum and faders at unity gain with 22
Hz to 22 kHz bandwidth unless otherwise specified. All In & Out
measurements made on balanced +4 dBu connectors. (+4 dBu into a line
input with faders at unity and the meter reading “0” will yield +4 dBu into a
balanced load or -2 dBu into an unbalanced load.)

Frequency Response

10 Hz – 65 kHz +0/-1 dB

(any input to any output at
nominal operating levels)

-3dB Point:

125 kHz

Connectors

MIC IN jacks:

Female XLR
(Pin 1 ground, Pin 2 +, Pin 3 -)

LINE IN jacks:

Female 1/4" 3-conductor phone
(Tip = +, ring = -, sleeve =
ground)

INSERT jacks:

Female 1/4" 3-conductor phone
(Tip = send, ring = return, sleeve
= ground)
Inserting plug to first "click"
allows direct output without
breaking normal signal flow

STEREO LINE IN and
STEREO AUX RETURN jacks:

Female 1/4" 3-conductor x 2

MAIN OUT BALANCED,
MONITOR OUT, and
AUX SEND jacks:

Female 1/4" 3-conductor phone
(Tip = +, ring = -, sleeve =
ground)

MAIN OUT -10 dBV jacks:

Female phono ("RCA") jacks

TAPE IN jacks:

Female phono ("RCA") jacks
