Adder AES-8

AES-8-Tx Features

A.    SAMPLE RATE (KHz) Allows the user to select one of four commonly used

sample rates. The sample rates are 48, 44.1, 44.056, 32 and EXT. for an
external sampling rate via. any one of the eight AES Digital Input jacks.

B.    SYNC OUT Provides sync signal to an external device. The rate is determined by

the SAMPLE RATE switch selection.

C.    FUNCTION Switches offers a selection between AES or Data usage. The Data

functions for the Adder-AES-8 are permanently disabled thus all six switches
should remain in the AES position.

D.    SYNC The red LED when lit indicates the unit is not receiving an external sync

signal. Functional only when EXT. is selected for the SAMPLE RATE.

E.    SUPPLY INDICATORS Four green LED’s show the status of each internal power

supply, -12, +12, -5, +5.

F.    POWER SWITCH Routes power to each of the four internal power supplies.

G.    FIBER Fiber-optic output sends optical data down fiber optic cable to the AES-8

Rx receiver unit.

H.    POWER INPUT Power receptacle receives 12V DC  from wall mount power

transformer or from some other 12V power supply. Receptacle is center pin
negative.

I.    AES  INPUTS Female XLR connectors provide eight stereo AES Digital Inputs.
