For all the different year breaks, Custom Autosound offers three different radios, the USA-230 for $169.95 and the USA-630for $234.95. The USA-630 comes with a USB port, the ability to add a CD changer and the ability to add Bluetooth. The Camaro radios from Antique Automobile radiolook 100% exactly like the original and even function like your original Camaro radio, all while having upgraded, modern internals. These radios feature mechanical push buttons, correct color "Roll-Over" dials,and a needle that actually moves when the radio is seeking for a radio station.Bias and equalization you've probably heard and used the terms for years, possibly without really understanding their effect on the quality of your recordings. If you're an engineer working with analog tape decks, you should know how to set decks up for different operating levels, bias for varying brands and formulations of tape, and how to calibrate your deck for a flat EQ response. Keep in mind that this is just the tip of the iceberg - there's enough info and tips on this to fill a book - but don't be afraid to learn how to do this yourself - you need this knowledge! Here's how it works: Your recordings will sound better (than if you left it uncalibrated for years!) and you won't be afraid to try new tape formulations or work on tapes from other studios. The bias oscillator in your analog tape machine serves two purposes: it erases the tape as it passes the erase head, and it provides recording bias, as a smaller amount is sent to the record head. Well, if the tape's already been erased, you might wonder, why do we need more of the same signal fed to the record head? Turns out that magnetization is not a linear function. The tape needs a bit of a shove to get it into the linear part of its transfer function. That shove is provided by high-frequency bias. Since the bias frequency is way beyond our hearing range (100- 200 kHz. in pro decks), it doesn't affect the audio being recorded too much. There is some low-level intermodulation distortion, however. ![]() We all understand the purposes of equalization. ![]() In analog recording, a built-in EQ is applied at both ends of the process. Recording equalization (set to AES/NAB or IEC/CCIR standards in most cases) is applied before our audio gets to the tape. Its purpose is to compensate for the characteristics of the recorder and the tape. Playback equalization must be applied to compensate for the nature of the medium. On playback, magnetic tape exhibits a 6 dB per octave rise in output. Thus the tape deck uses a -6 dB per octave low-pass equalization to obtain flat frequency response.Īrmed with this knowledge, we are now ready to match the tape machine's electrical characteristics to the tape we wish to use for recording. This is a tape, which has been recorded at a known level of magnetism for at least three frequencies, 100 Hz, 1 kHz, and 10 kHz. GM backup camera gives the advantage of situating the display where drivers are accustomed to looking when backing up.You will use this to set playback levels and EQ.Other versions use a portion of the rearview mirror as a monitor. Since most newer vehicles have an existing screen for the entertainment system, climate control, navigation and other functions, drivers used that display for the backup camera system. But for the desired images, they are usually mounted hidden in the bumper, near the license plate, in the trunk lid, or in the tailgate of an SUV or pickup truck. Drivers can mount their backup cameras anywhere they like.They designed the system to correct this so the view on the display makes sense. If you were looking at a direct feed of what the camera sees, the image reversed and you’d steer left when you wanted to go right. This is so the orientation is correct when you look at it.Rather than transmitting the picture that a typical camera might see, manufacturers designed backup camera systems to send a mirror image to the monitor. ![]() ![]() The complexity begins with how the camera captured the image.When you put your car into reverse, your GM backup camera mounted at the rear of the vehicle turns on and sends an image to a monitor to show what’s behind you.They are getting more high-tech all the time. Backup camera systems, even at their most basic, are fairly sophisticated pieces of technology.
