AV-61
AUDIO/VIDEO 6-WAY DISTRIBUTION AMPLIFIER
GENERAL INFORMATION
• The AV-61 is a low noise, low distortion unity gain distribution amplifier for line level stereo audio and video
baseband signals.
• It splits audio and video signals six ways with no signal loss.
• It prevents audio distortion in multiple zone systems by buffering the source units from the loading effects
of several AV receivers or preamps.
• The space saving "flat pack" design allows great flexibility in mounting and positioning.

AV-61 Panel Descriptions
1. INPUT jacks. Connect to the corresponding output jacks of the source component (Laser Disc player,
VCR, CD player, Tuner, etc.).
2. 16V DC Supply Jack and Power Indicator LED. The 16 VDC 300 mA power supply (included) is
plugged in here. The LED will light when power is applied.
3. OUTPUT jacks. Connect to the corresponding input jacks of AV receivers, preamps, TV monitors,
VCRs, etc.
4. Mounting Holes.
TYPICAL APPLICATIONS
Audio/Video Distribution
Fig. 2, shows the distribution of video (baseband) and stereo audio signals to three TV monitors and three
VCRs from a singleDVD player via the AV-61. Many other combinations of AV or audio only products could
be configured in a similar manner.
Zoned Systems
One of the most useful applications of the AV-61 is to drive several receivers or preamps from common
sources in multiple zone A/V systems. Fig. 3 illustrates the use of four AV-61's to drive four receivers from
four sources in a typical four zone system. Use it when configuring zoned systems with the Xantech 795
and 796 IR Zone Controllers.

INSTALLATION NOTES
1. Use high quality low-loss cables for all A/V connections. For runs in excess of 10 feet, use low-loss
RG-6 coax. Runs in excess of 50 feet are not recommended.
2. AV-61 Distribution Amplifiers, used in zoned systems, prevent loading mismatch on the source
components & audio distortion on music peaks when some zones are turned off while one or more are
still on. You need one AV-61 for each source, as shown in Fig. 3.
3. The distribution amps should have their AC power switched on and off along with the common source
components in zoned systems. Refer to the Xantech model 680 AC Switcher instructions for details.
4. The A/V Receivers also need AC power management. Refer to the 680 instructions for details.
5. Fig. 3 assumes the use of A/V Receivers having base-band video switching capabilities.
