AV Switching & Distribution
Keene KPDA 1:5 Component Video & Audio Distribution Amplifier
• One input, five fully buffered outputs
• Wide bandwidth HDTV capable
• Broadcast quality high speed video buffers
• Use for component video, RGBs video, RGsB video
or four x composite video plus stereo audio
• One video channel may be used for digital audio
The KPDA is a high quality audio/video distribution
amplifier, allowing one video and audio source to
simultaneously supply up to five other devices. It uses
very high quality high bandwidth ICs to ensure that
each output is not discernible from the input, making
it ideally suited to driving multiple displays or making
multiple copies from one source. There are two stereo
audio channels and four video channels, making it
suitable for use with component video, RGBs video,
RGsB video or 4 x composite video plus audio. Any of
the video channels can also be used for digital audio
if desired.
Specifications:
• Power requirements: by external supply to DC input
socket, (2.1mm centre positive) 12-18v DC @
300mA or greater
• Video: 5 buffered video outputs bandwidth 75MHz
(up to 1080p)
• Level - composite / luminance 1v pp, chrominance
0.3v peak to peak
• Distortion components <–50db up to 10MHz
• Open circuit voltage gain is X2 (unity gain when
correctly terminated)
• Back terminated series 75 Ohm outputs for
reflection free performance
• DC coupled on all outputs
• Slew rate up to 500v/uS
• Audio: 5 buffered audio outputs
• Distortion <0.1%
• Bandwidth 20Hz – 30kHz
• Output impedance, <1k ohm each output
• Input impedance >10K ohm
• Unity gain
• Dimensions: 220mm x 104mm x 43mm
• Weight: 780g (excluding power supply)
Keene SDA 1:5 Scart Distribution Amplifier
One input to five outputs, fully buffered using
broadcast grade video amplification ICs. Pin 8 is routed
through (if the input goes high all the outputs go
high) and every pin connection is carried through
making it suitable for composite, S-video, component
or RGB. Supplied in a robust metal case this is ideal for
displaying one signal on multiple TVs or for making up
to five simultaneous copies from one source. Mains
adaptor included.
Specifications:
• Power: 12-18v DC @ 300mA
• Video: 5 buffered video outputs
• Video bandwidth: 50MHz
• Video level: Composite / Luminance 1v pp,
Chrominance 0.3v peak to peak.
• Video distortion: < -50db up to 10Mhz
• Back terminated series 75R outputs for reflection
free performance
• DC coupled on all outputs
• Slew rate up to 500v/uS
• Audio: 5 buffered audio outputs
• Audio distortion: <0.1% Bandwidth 20Hz - 30KHz
• Audio output impedance: <1K ohms each output
• Audio input impedance: >10K ohms Unity gain
• Dimensions 219 x 115 x 37mm
• Weight 725g (exc supply & cables)

Keene KDA 1:4 AV Distribution Amplifier
The Keene KDA distribution amplifier has one set of inputs for composite video, s-video and stereo audio and four identical sets of outputs, each output being
indistinguishable from the input.
Uniquely, the Keene Distribution Amp also has a switchable line drive feature, giving the ability to send audio and/or video over much longer cable runs than normally possible
(up to 100m dependant on cable). The KDA may be ‘daisy-chained’, that is to say the output of one KDA may be fed into the input of another. Used in such a configuration,
five KDA’s may be used to provide up to 16 AV outlets from one AV input.
This product is ideal for:
Sending an AV signal to multiple displays
Sending an AV signal down a long cable run (up to 100m with the right cable)
Making up to four simultaneous recordings from one source
Sending line level audio to amplifiers in other rooms
Specifications:
• Power: 12-18v DC @ 300mA or greater (mains adaptor included)
• Video bandwidth: 50MHz distortion: <50db up to 10Mhz
• Back terminated series 75ohm outputs for
reflection free performance
• DC coupled on Composite video and Luminance outputs
• AC coupled on Chrominance output
• Slew rate up to 1000v/uS
• Audio distortion: <0.1% bandwidth: 20–30kHz
• Audio output impedance: 1K ohms each output
• Audio input impedance: >10K ohms
• Dimensions 144 x 111 x 64mm
• Weight 680g (exc supply & cables)
