What the Universal Audio 1176 RATIO & METER Parts are?

Above all, we need to know what Universal Audio 1176 is? The initial Universal Audio 1176 was made by UA creator M.T. “Bill” Putnam, as well as stood for significant development in limiter innovation. The initial compressor included solid-state wiring and ultra-fast 20 split second FET gain decrease, the 1176 is a user-friendly “desert island” compressor that has provided its personality as well as the punch to several of the best recordings in history. So it is a very classic & popular model, since 2001. Even now, people also recall it with praise because of its perfect performance.

However, this article only shows you the RATIO and METER parts of it. This is for someone who needs to purchase or repair an 1176 limiting amplifier but does not know how to communicate with the manufacturer or retailer.

In fact， the 1176 limiting amplifier RATIO & METER are a kind of push button switch subassembly, which is also called ganged switch.

The RATIO pushbutton ganged switch is used to determine the compression ratio of the plug-in. So that it can limit the sound output. Such as the Ratios of 20:1, 12:1, 8:1, 4:1, 2:1, etc. Meanwhile, the ratios of 20:1, 12:1, 8:1, and 4:1 are available for most of 1176 apart from the UA 1176AE. Because the 1176AE has the 20:1, 8:1, 4:1, and 2:1 modes.

• To choose the different mixes of numerous switches, change+click the Ratio buttons. Mixes are restricted to the settings that really influence the audio in the equipment. See Available Multi Switch Modes for the combinations.
• For the mixes with 3 or even more buttons, the shift-clicking the external buttons will instantly involve the internal buttons (the internal switches can not be disengaged; such mixes do not influence the audio in the device.
• These models can be utilized as “tone boxes” without compression/limiting by disengaging the Proportion control completely (all Ratio buttons “up”). This is completed by clicking any Ratio switch so just one button is involved, after that shift-clicking the involved button so none are involved.

• On one hand, the RATIO switch is composed of four single push button switches, both of them are the same parameters. In this process, the buyer can choose the function you need, like the PT, Self-lock or momentary function, PCB type, and so on. But the PBN-N2A35-AAG is the push switch used in the universal audio 1176.
• On the other hand, when the 4 single switches are composed in one subassembly, the buyer also can choose their function of it. Generally, there is about 4 function for your options, the OA(NON-LOCK), EE(SELF LOCK), GR(INTER LOCK), and RE(RESET). Besides, the timing type also has the SHORTING and NON SHORTING for choice. While the UA 1176 classic limiter is used the INTER LOCK and NON-SHORTING type.

The METER parts can show the amount of gain reduction or output level by the METER function setting.

• Firstly, the part will be disabled and the processor usage is reduced when the OFF switch is pressed;
• Secondly, the Meter will show the Gain Reduction degree in dB when we set it to the GR function;
• Thirdly, when we select the +8 or +4, the VU Meter shows the output degree in dB;
• Fourthly, when set to +4, a meter analysis of 0 corresponds to a result level of +4 dB.
• Fifthly, When the Meter Feature is readied to GR setting as well as several Proportion switches are involved, the Meter will certainly show up to behave oddly.

At first, because the METER can OFF the switch, one of them need to play the role of a power switch, and the other 3 switches are the signal switches to control other function. Require these 2 kinds of switches are different parameters.
Generally, the function of METER also have some difference from the RATIO, for more details, welcome to click the link to see the PBN-4-15T-0056 details, this is the model used as the METER in the 1176 classic limiter. For more details, welcome to contact us or visit our Alibaba shop.
