Kustom KHS-6640 Owner's Manual - page 20
Can I control volume and source selection with a wireless remote?
Yes, the KHS6S and the KHS6D controllers have a built-in IR emitter that will teach learning remote
the Kustom IR codes for volume, source selection, and mute.
How do I control IR if I am using more than one 6640 amplifier?
The best solution is to use Y cords with two 1/8 male ends going to a 1/8 female end. This works
with the 4 source outputs as well as the 4 summed outputs.
Can I use more than one controller within a single zone?
Yes, the controllers can be tied together via a cat. 5 Y cord or an RJ45-Y adapter. We suggest using
only two controllers within one zone. It is also possible to control two zones with one controller.
Can I use more than one pair of speakers within a single zone?
The 6640 is intended to be used with two 8 ohm speakers per zone. It is equipped with line level preamp
outs for each zone. You can line out to any external amplifier using standard RCA cables. This makes
it possible to power additional speakers, or a powered subwoofer for surround sound systems.
Do I have to have all zones playing music to be able to hear the doorbell and page?
No, the page and doorbell features will work regardless of the status of the zones. You can, however,
use internal switches on each zone to defeat the doorbell and page, or allow the doorbell and page
without muting the system.
Can I program functions into a macro other than my audio equipment?
The 6D controller will learn and store any IR code in its memory. Once an IR command is programmed,
that can then be used as part of a series of macro commands. It is important to note that the 6D can
only do macros on commands that have already been stored into the controller's memory.
Do I need to have a backup for the memory in case of a power outage?
No, the 6D controller has a non-volatile memory that will retain its memory once the controller has been
programmed.
How do I utilize the doorbell and page features?
The doorbell and page can be wired with simple two-conductor doorbell wire or standard twisted pair
wire such as Cat. 5 or Cat. 3. The doorbell can be lined off of the existing doorbell transformer, or from
the doorbell strike on the phone system. Since this feature utilizes a voltage to trigger an internal
closure, a 9-volt battery will trigger the doorbell chimes. The page function can be used in two different
ways. The simplest method is to take the audio line out from your phone system directly to the audio
in on the 6640. The 6640 is designed to sense the incoming signal and mute the system until a signal
is no longer present, at which point it will return to normal operation. It may be necessary to adjust the
sensitivity on the page/doorbell board of the 6640 to compensate for additional noise in the phone line.
An alternative solution to eliminate sensitivity problems between the 6640 and the phone system is to
add a second power supply (this can be a typical "wall wart") to one of the contact relays on the phone
system and from there to the mute input on the 6640. This will mute the system regardless of an
incoming audio signal, and will remain muted until the phone is hung up.
What if none of the lights on the controller come on?
It could be that the POWER button is not depressed on the KHS6640. Next verify that you have a
source plugged in and playing. Remember that the 6640 will go into standby mode after approximately
2 minutes if no incoming signal is detected. If both of these conditions have been met then you probably
have an incorrectly wired Cat-5 cable. The correct pin assignment from end to end is: 1 to 8, 2 to 7,
3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, and 8 to 1.
What does it mean if the red power LED is lit on the controller, but none of the source LEDs
is lit?
This condition indicates that the controller is muted. Press the mute button to turn off the mute in
that zone at which point one of the source LEDs should light. If this doesnt solve the problem, and
