Kustom KPM8420 owner manual FAQ Frequently Asked Questions

FAQ Frequently Asked Questions:

1.How many speakers can I use with the KPM8420? ANSWER: Most speaker cabinets today are 8-ohms. For the sake of this question we will assume this is the case. You can use a total of four 8-ohm speakers with the KPM8420: Two for the A power-amp and two for the B power-amp. DO NOT plug all four speakers into one power-amp.

2.Can I use two different effects on my vocal mics? ANSWER: Yes! One popular setting for vocal mics is to use one digital effects section for reverb and the other effects section for delay. Here is an example: Set Effects 1 to ECHO and Effects 2 to SMALL HALL. Adjust the amount of reverb first by turning up the EFFECTS 2 control on the desired individual channel. Then, add the desired amount of ECHO by turning up the EFFECTS 1 control on the same individual channel. Set levels to obtain the desired effect.

3.Can I use one effects section for my vocals and the other for my instruments?

ANSWER: Yes! This is one of the truly unique

features of the KPM8420. Here is an example: a little Chorus on an instrument can really sweeten the sound, but chorus effects on vocals are a disaster. First set up the Instrument channels: Set the sound of EFFECTS 2 to Chorus or Chorus/Rev in the master section of the mixer. Turn up the EFFECTS 2 send on the individual instrument channels to the desired level. Now the vocal channels: Set the sound of EFFECTS 1 to one of the reverb selections. Turn up the EFFECTS 1 send on the individual vocal channels to the desired level.

4.Can I use a sub-woofer without using the fixed crossover from the KPM8420?

ANSWER: Yes! Use the MAIN preamp output jack to feed a full range main signal to your sub-woofer or active crossover and power-amp.

5.Can I use both Power-amps for mains or monitors?

ANSWER: Yes! To use both power-amps for mains, set the POWER AMP ASSIGNMENT switches & to the UP (MAIN) position. To use both power- amps for monitors, set the POWER AMP ASSIGNMENT switches (#41*) to the DOWN (MONITOR) position.

6.Can I use another non-powered mixer with my KPM8420 to get more channels?

ANSWER: YES! Take the Line level output of the external non-powered mixer and connect to one of the LINE ¼” inputs . Make sure the pad switch is NOT pressed in. Set the individual channel tone control to the twelve o'clock position and bring up the channel volume control as needed.

7.Can I use an external Power-amp with my KPM8420?

ANSWER: Yes! For MAIN Master feed, connect a shielded high-Z instrument cable from the Preamp output MAIN jack to the Line level input of the desired external power-amp.

8.Not all of my microphones are condenser type. Will using the Phantom Power in the KPM8420 damage my non-condenser mics?

ANSWER: No. You can safely use a combination of condenser and dynamic microphones at the same time.

9.I have the Digital Effects Control knobs on Channel and Monitor turned up but still do not hear any effects through the monitors. Why? ANSWER: The Main volume on the channel is not turned up . Because the effects send from the channels is Post Main, there must be signal present at that channels main output.

9.I have a channel that I want in the Mains but not in the monitors. The Monitor Volume on the channel is all the way down but still comes through the monitors. Where is this coming from? ANSWER: It is coming from one or both of the Digital Effect Monitor controls & along with one or both of the channel Effect controls & being turned up. Fix the problem by turning down Effect 1 or 2 on the channel, or Effect 1 Monitor or Effect 2 Monitor on the digital effect.
