AUDIO INPUTS
MICROPHONES
Supervisor and Operator Headsets Inputs for two simulated carbon telephone-style headset
microphones similar to Plantronics model HS-0309-1.
Typical input = 280 mVp-p. ALC/clipping threshold = 600
mVp-p. DC bias = 3.0 ±0.5 Vdc at 50 ohms.
Desk Mic Input for an electret-type microphone similar to Ericsson GE
part number 19C851086P10 or P11. Typical input = 300
mVp-p. ALC/clipping threshold = 600 mVp-p. DC bias = 5.7
±0.5 Vdc at 1000 ohms.
Boom or Gooseneck Mic Input for a dynamic microphone similar to Shure Bros. model
VR300 / Ericsson GE part number 19C337100P1. Typical
input = 4.4 mVp-p. ALC/clipping threshold = 9.5 mVp-p. No
dc mic bias provided.
LINE A, B, C & D Balanced 2-wire 600-ohm inputs each designed to receive
voice bandwidth audio from one pair of a 4-wire 600-ohm
twisted-pair transmission system provided by the CEC/IMC.
Capacitively coupled and transformer isolated. Typical input
= -5 dBm. Input range = -20 to +10 dBm.
CALL DIRECTOR PATCH (LINE D) Balanaced 600-ohm input designed to accept audio from a
Call Director device similar to Plant Equipment model 3780-
L1-TT-010. Capactively coupled and transformer isolated.
Typical input = -25 dBm. Input range = -37 to +8 dBm.
PAGER Unbalanced 600-ohm input designed to accept audio from a
paging tone encoder or similar device. Typical input = 140
mVp-p. Input range = 28 mVp-p to 2.0 Vp-p.
