Pressure limit of the function keys 1

 Pressure limit of the function keys
1) Input Gain (Input
Gain): regulation relative to the compressed size of the signal level threshold, 0dB said balanced amplifier input signal does not improve, or attenuation. Is that dB improved means more output signal is compressed.
(2) Door Threshold (Gate
Threshold): adjust the gate limit, below this limit signals, including noise, to gain attenuation 35dB. shun clockwise stressed that gated limit increased, more signal is gated Subject be attenuated. anti-clockwise tone is full, close the door threshold. This is not the door threshold of the input gain control.
(3) start-up time (Attack
Time): that from the output level threshold detector over to the compressed signal compression to the required compression ratio of the time required to transfer a clockwise direction, slow down the process, anti-clockwise direction of transfer, acceleration the process. It is part and voltage-controlled part of the detection signal level increase of the speed of response.
(4) recovery time (Release
Time): said compression section (output level detector and amplifier section pressure of modern ) on the response signal level drop speed. from the compressed state to return to the normal state below the threshold compressed the time required.
(5)
compression ratio (Ratio): the role of regulating the strength of compression. 3: 1 means the signal compressed more than the threshold for each additional 3dB, the output increased by only 1db; 1: 1, said pressure limit can not afford to compression effect; more than 5:1, there is significant compression effect; more than 10:1, there are obvious limitations effect; i: 1, said pressure limit from the limiter function, voltage-controlled amplifier output will not increase. compression threshold be the limiting threshold.
(6) compression threshold (Compress
Threshole): regulation by signal compression Datum. anti-clockwise transfer by compressing the signal more tune full clockwise, in the 20dB, most signals are not compressed.
(7) Output Gain (Output Gain): used to restore the signal compression the overall processing gain, it only affects the whole output.
(8) normal / connect stereo switch (Normal / Linked
Switch): two-channel for stereo, press it, and gain reduction by the sound Road, a master, to retain the original balance of the sound and audio-visual, channel 1 start time, recovery time, compression ratio, compression threshold control of two channels. But Channel 2's input gain and output gain control still plays role is to balance the interests of the general regulation and the same channel 1. But the key to pop up, the two channels independently.
(9) Gain Reduction Table (Gain Reduction
Meter): that the size of gain reduction. to 5dB for the level, the first light on only for 1dB gain reduction.
(10) earthing switch (Ground
Switch): it is covered with a switch after the machine. machine termination of the circuit board to the power of public ground and chassis form a metal railing to loop, can cause hum, pick up the switch, separating the rack with all the signal ground, cut off the ground loop. but the power is still connected to ground and the rack to ensure the safety and radio frequency interference shielding.
(11) side chain input and output (Side Chain input and
output): a special application
