Description


Solid Signal is an Authorized Reseller of Channel Master products.
Solid Signal is an Authorized Reseller of Channel Master products.
The Channel Master Amplify was designed to be the most versatile TV antenna amplifier on the market. Channel Master has designed, manufactured and sold television antenna amplifiers for over 60 years and has led the industry with popular amplifier models designed for professionals including our Titan 2 amplifier models ( CM-7777 and CM-7778). Through the years, installers and industry experts have touted these professional models as the best TV antenna amplifiers on the market.

As the industry has evolved, consumers have taken on their television antenna and home entertainment projects as do-it-yourself projects and are relying less and less on professional installers. Taking in consideration this trend, our team of industry analysts determined there was a need for a professional quality amplifier that was better positioned for consumers to install themselves. The Channel Master Amplify brings together the best of our most popular professional amplifier models along with new features to accommodate consumers performing their own installations. Indoor/Outdoor Heavy-Duty Housing

Competitor TV antenna amplifiers are typically constructed of plastic and designed for indoor use only. The Channel Master Amplify, like our Titan 2 professional models, is constructed of a die-cast metal housing with weatherproof ports to support indoor and outdoor installations. The flexibility of being able to install the Amplify indoors and outdoors allows use with an indoor antenna and the ability to upgrade to an outdoor antenna in the future without having to purchase a new amplifier.

Adjustable Amplification: Most people think more is better. This is not always the case when talking about TV antenna amplifiers. We see this all the time when consumers purchase our highest gain professional amplifier (CM-7777) without having the signal measurement equipment to determine how much they really need to amplify their signals. In many cases too much signal will do more harm than good to your overall signal and reception quality. The Channel Master Amplify eliminates the need for a consumer to be conscious about signal strength while still providing an industry leading 30dB of gain. With the inclusion of an easy push button gain switch, you can easily start with the high setting of 30dB gain and if you determine that this much signal has a negative impact on your reception, you can simply push the button and switch to the low setting of 17dB which in most cases will be a safe amount of gain and make a noticeable difference in signal quality. *When installed indoors directly behind a television set, it is recommend NOT to use the high (30dB) setting.

Key Features
  • Improves signal quality
  • Decreases pixilation
  • May increase number of channels
  • Ultra low noise, and an adjustable gain (17 dB/30 dB)
  • Blocks LTE interference from 3G/4G Smartphones and transmitters, and EMI & FM Out of band filtering (Does not pass FM signals)
  • Heavy duty rating for indoor or outdoor use, Mast mounted for close proximity to antenna


Features


  • Power supply and pre-amp are connected to the antenna using RG6 coax cable. An RG6 cable is run from antenna to pre-amp, from pre-amp to power supply, then from power supply to television. Power supply does not have to be outdoors

  • Cool running, redesigned 117 VAC power supply, Model 0747 is included with each model. Output voltage is +15VDC. UL and cUL listed, Power supply also available as a separate model

  • Power supply goes in the building and sends voltage up the antenna cable (see diagram in Specifications tab)

  • Surface-mounted components for automated production and consistent high performance

  • Preamplifier and its power supply can withstand up to 140° F temperatures

  • You can use the 1296F as a variable attenuator to control the Db Gain

  • Improved circuitry for full lightning and surge protection

  • Optimum filtering for rejection of out-of-band signals

  • Makes up for signal loss from long cables and splitters

  • Compare with other pre-amps by clicking here

  • Gain: 30 dB, 54 to 1002 MHz

  • Includes a switchable FM trap

  • Manufacture's may vary depending on availability

Specs


 A Pre-Amplifier (pre-amp) is a mast or antenna mounted amplifier used primarily to eliminate "snow" on the TV screen. Snow is actually electrical noise that is generated by the TV receiver and other electrical devices. The objective of any antenna installation is to deliver enough signal to the TV set to override the noise (snow). A "weak" signal is one that is not strong enough to override the level of the noise in the set. Another obstacle is the signal loss incurred while travelling through the transmission line connecting the antenna to the TV set. An antenna that has acceptable gain at the antenna tapoffs but encounters excessive loss due to long cable runs will also deliver a "snowy" picture to the TV set due to not enough signal makes it to the set to override the noise level. A pre-amp would be used to compensate for the losses in the transmission line as well as the noise level of the set.

TITAN 2TM

MATV Mast Mounted Preamplifiers

The Titan range of mast mounted amplifiers has been completely reengineered and updated. These amplifiers represent the ultimate in preamplifier performance. They are designed for use as an ultra low noise, ultra high gain preamplifier for deepest fringe applications and MATV headend applications.

Their very high signal handling also makes them suitable for use as a mast mounted, ultra low noise distribution amplifier for use in small MATV systems. All models feature 75 ohm, input and output connections in line with modern headend engineering practice.

SPECIFICATIONS:
• Number of Inputs:  1 (VHF UHF
• Input and Output Impedance:  75 Ohms
• Input and Output Connectors:  F Type Connectors
• Gain 30db

The power supply that comes with this amp goes inside the building, so you do not have to run a separate cable for power.  The unit inside the building injects voltage up the coax cable, so there is no need to put a power supply outside.  Be sure not to place any devices in-line between the pre-amp and power supply, or the voltage will be blocked and the unit will not function correctly.
