UNBALANCED RCA -20dB LO-Z INPUT: User must provide his own 20dB

line stage which should include an INPUT LEVEL CONTROL into this extemely
low impedance input which is at "virtual earth" with an in line 4K resistor.

J UNBALANCED XLR INPUT: 25K "bridging" input impedance. We have

utilized the latest in op-amp design, The Linear Technology LT1028, in our
standard version of front end circuitry. The LT1028 has the lowest noise and
THD figures of any currently manufactured op-amp.

The pinout is as follows:

PIN 1 GROUND
PIN 2 HOT (+)
PIN 3 GROUND

K BALANCED XLR INPUT: 10K "bridging" input impedance. To achieve

optimum quality from this input, ONLY A TRULY BALANCED (i.e.; fully
floating or symmetrical) drive should be employed.

The pinout is as follows:

PIN 1 GROUND
PIN 2 HOT (+)
PIN 3 LOW (-)

PLEASE NOTE: Since this input is intended for use with an electronically

balanced console output, NO means of internal level control has been provided in
this converter unit for this input.
