The 104LN is a unique piece of equipment that combines the functions of a distribution amplifier and a line driver. It accepts one composite video input and distributes a signal to four buffered outputs; gain and EQ controls are used to adjust the output level and equalization. The controls are used to compensate for signal losses in such situations as long cable runs. This model offers a differential input for noise elimination.

The STA-2A Dual High-Gain Line Amplifier from RDL is a dual-channel, line-level audio preamplifier with up to 24 dB gain. The gain is adjustable from unity to +24 dB using a 25-turn precision audio taper trimming potentiometer.

Each channel is identical and audio inputs are bridged at 20 kOhms to accept either balanced or unbalanced audio signals. The STA-2A's output and line-driver circuits are designed to drive long balanced audio lines into 600-Ohm loads. This unit features wideband circuitry for excellent phase response and improved clarity.

It offers RDL's SupplyFlex power input configuration that can be fed from a ground-referenced 24 VDC power supply, a floating (non-ground-referenced) 24 VDC power source, or a bipolar power supply.

The MLA-1 from JL Cooper is a wall-panel mounted MIDI line amplifier, featuring four MIDI inputs and four MIDI outputs, that would normally be accessed via a separate MIDI-jack panel. This allows MIDI signals to be sent through 1,000 feet or more of common twisted pair wire.

The unit is suitable for school installations, recording facilitates, stadiums, arenas, hotels, amusement parks, or other facilities where MIDI messages are required to be sent a long distance, or to multiple locations. Since the MLA-1 converts the MIDI input to a proprietary format, a second, compatible unit is required at the termination of the long cable run.

The MLA-10 from JL Cooper is a MIDI line amplifier, featuring four MIDI inputs and four MIDI outputs that can be sent through 1,000 feet or more of common twisted pair wire. For large installations, the 50 foot limit of standard MIDI transmission can now be overcome.

The unit is suitable for school installations, recording facilitates, stadiums, arenas, hotels, amusement parks, or other facilities where MIDI messages are required to be sent a long distance, or to multiple locations. Since the MLA-10 converts the MIDI input to a proprietary format, a second unit is required at the termination of the long cable run.

The MLA-XLR from JL Cooper is designed to act as a single channel, bi-directional, long distance amplifier or driver for MIDI signals. While the normal MIDI protocol specifies a maximum cable distance of about 50 feet, this is sometimes not sufficient for some installations.

The MLA-XLR takes a MIDI input and converts it to a balanced, differential signal using the RS-422 specification. At the other end, another MLA-XLR detects the signal using a sensitive receiver that has a high degree of noise immunity. Connecting the two MLA-XLRs are two standard, shielded, twisted pair microphone cables.

The combination of a low impedance, differential driver coupled with a sensitive differential receiver signal lends itself to long distance, error free installations and making it possible to send a MIDI signal through 1000 feet of cable or more. The MLA-XLR is compatible with the JLCooper MLA-1 and MLA10.

The Kramer 1:1 Computer Graphics Video Line Amplifier is a line driver that compensates for signal losses (signals exceeding UXGA, 1600 x 1200 pixels) in long cable runs. The line amplifier is applicable for dual monitor and presentation systems as well as for remote transmission and cable equalization.

The Kr-isp Advanced Sync Processing technology, which can be enabled or disabled, restores the sync signal waveform and ensures compatibility with an array of computers (even at low sync level). The amplifier has 1 XGA input and output on a 15-pin HD connector and is compatible with HDTV component video signals using the breakout cable (Kramer CGM/3RVF). S/N ratio of 75dB means clear signals without any grainy video noise.

The 500MHz bandwidth at -3dB ensures transparency even at the highest resolution. An EQ trimmer adjusts the cable compensation equalization level for the output. The optional RK-3T rack adapter allows 3 units to be mounted side-by-side in a 1U rack space.
