echnical parameters:

 

Number 1 input: 4* AES 25 needle D bus interface provides 4 AES/EBU channel pair input.

 

Input impedance: 110_, balance

 

Numbers 2 and 3: 1 * AES positive BNC connector, unbalanced but floating, in line with AES-3id-1995/SMPTE 276M requirements.

 

Input impedance: 75

 

Digital 4 Input: Optical Fiber Interface

 

Multi-channel analog input: 8-channel 25-pin D bus interface, balanced simulation, 10K differential input impedance.

 

Reference level: 300 mV

 

Asynchronous input: 2-channel, RCA connector, 21K input impedance, input level adjustable microphone input; XLR interface, standard pin, 10K differential input impedance, using 12V phantom power supply, gain adjustable.

 

Main audio output: 8-channel 25-pin D-type common interface, balanced, floating, analog, 100_differential output impedance, load must not be less than 600_.

 

Auxiliary output: 2 channels, unbalanced simulation, 100_output impedance, RCA interface.

 

Reference level: 200 mV.

 

Hearing impaired mode output: mono-channel, unbalanced simulation, 100_output impedance, RCA interface left, middle and right channel mixed signal, and weighted the middle channel; output level: 200 mV.

 

Always output: 7/8 channel of 4*AES input provides additional functions, such as output H/I and VI-N signals - the fixed level output is not processed by room EQ and is not controlled by volume knob.
