[. . . ] The T8's audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the T8 a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed for use with impedances from 600 Ohms to 100k Ohms. What further sets the T8 apart from other lesser isolation boxes is its connection versatility. We have provided XLR, ¼" phone, and RCA type phono connections on all inputs and outputs. This allows it to easily fit into virtually any audio system and be the clean patch point between all types of systems. All ¼" and RCA phono jacks are on the front and all XLR jacks are on the rear. You can use any combination and since the jacks are directly paralleled you can also use them as signal taps or as a signal splitter. The T8's mounting ears are reversible so you can have either the ¼" and RCA phono jacks on the front or the XLRs on the front. This maximizes flexibility in cabling your system. Whether you need an interface between a computer based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of multiple signal sources from your recording equipment, or in many cases, just a safer connection between two audio systems, the T8 can accommodate. The 19" 1U black all steel case and its all passive design allow the T8 to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D. J. , and virtually any PA application. It is equally valuable in a variety of studio and AV applications. Its full feature set, rugged construction, and high-end specifications make the T8 the obvious choice. APPLICATIONS: LIVE SOUND, D. J. Long unbalanced cables are more susceptible to picking up hum , Using the T8 to help balance these and eliminate any hum. When DJs set up for different jobs there is a potential to pick up hum due to the differences in house wiring, using a T8 Eliminates the potential for hum. 1 MIXERS/FIXED INSTALLS/RECORDING/BROADCAST/VIDEO Use the T8 to eliminate ground loops when using multiple mixers. Taking mixer unbalanced sends and achieving true balanced monitor outputs. Using the T8 between video/broadcast rigs eliminates the potential for hum and loop noise. POWER AMPLIFIERS Hum, ground loop noise can be created between multiple amplifiers. This can be eliminated using the T8 on each of the amplifiers input lines.
