Output Tubes 6L6GC — After replacing output tubes, output tubes bias voltage should be checked with Standby switch set to On, no signal input, and all controls set to minimum. If output tube bias voltage is not correct, amplifier will sound unusually distorted with mushy audio and output tubes may overheat. Normal output tube bias voltage should be — 52VDC on Pin 5 of all output tubes. For best results use matched output tubes.

GTA-1260 specifications

Nady Systems has established itself as a prominent player in the audio equipment industry, and one of its standout products is the Nady GTA-1260. This versatile wireless microphone system is designed for both professional musicians and performers, offering robust features that enhance live sound and reliability.

The GTA-1260 operates in the UHF band, providing a broad frequency range that minimizes interference from other wireless devices. With up to 160 frequencies to choose from, users can easily find a clear channel, ensuring stable and high-quality audio transmission. This feature is particularly beneficial in environments where multiple wireless systems might be in operation, such as concerts and events.

One of the key characteristics of the GTA-1260 is its dual-channel receiver, which allows for the use of two microphones simultaneously. This makes it an ideal choice for duets, interviews, or any situation where more than one speaker is required. The receiver is equipped with a clear LED display that shows both the selected frequency and the battery status of the transmitters, ensuring users are always informed about the performance of their system.

The handheld microphone transmitter included in this system boasts a dynamic capsule, providing a warm and natural sound reproduction that is ideal for vocals. It features a comfortable grip and ergonomic design, allowing for ease of use during performances. Additionally, the transmitter operates on AA batteries, offering a substantial battery life that ensures uninterrupted operation for long gigs or events.

Nady Systems has also integrated advanced technology into the GTA-1260, such as automatic frequency scanning. This feature automatically searches for and selects the clearest frequency available, simplifying setup and enabling users to focus on their performance rather than technical details.

For added flexibility, the system supports both handheld and bodypack transmitters, making it suitable for a wide range of applications, from solo acts to full band performances. The bodypack transmitter can be connected to a variety of microphones or musical instruments, expanding the usability of the GTA-1260 beyond just vocal applications.

In summary, the Nady Systems GTA-1260 wireless microphone system is engineered for reliability and performance. Its advanced technology, dual-channel capability, extensive frequency options, and high-quality audio output make it an excellent choice for users looking for a professional wireless solution that meets the demands of live performances.
