ENGLISH

Danger Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time.

The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures:

DURATION PER DAY (HOURS) SOUND LEVEL (dB)

According to OSHA, any exposure in the above permissible limits could result in some hearing loss. Ear plugs or protectors in the ear canal or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss. If exposure in excess of the limits as put forth above, to insure against potentially harmful exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of inducing high sound pressure levels, such as this amplification system, be protected by hearing protectors while this unit is in operation.

Danger L‘exposition a des niveaux eleves de bruit peut provoquer une perte permanente de l’audition, Chaque organisme humain reagit differemment quant a la perte de l’audition, mais quasiment tout le monde subit une diminution de I’acuite auditive lors d’une exposition suffisamment longue au bruit intense. Les autorites competentes en reglementation de bruit ont defini les expositions tolerees aux niveaux de bruits:

DURE EN HEURES PAR JOUR INIVEAU SONORE CONTINU EN dB

Selon les autorites, toute exposition dans les limites citees ci-dessus,peuvent provoquer certaines pertes d’audition. Des bouchons ou protections dans l’appareil auditif ou sur l’oreille doivent etre portes lors de l’utilisation de ce systeme d’amplification afin de prevenir le risque de perte permanente de l’audition, Dans le cas d’expositions superieures aux limites precitees il est recommande, afin de se premunir contre les expositions aux pressions acoustiques eIevees potentielIement dangeureuses, aux personnes exposees aux equipements capables de delivrer de telles puissances, tels ce systeme d’amplification en fonctionnement, de proteger l’appareil auditif.

MONITOR MASTER GRAPHIC EQ:

This set of slide controls adjusts specific

frequencies in order to tailor the overall sound to an acoustical environment or an intended sound.

FEEDBACK NOTCH :

This control is a narrow notch that can remove a

problem frequency that may causing excessive feedback. To activate this feature, slowly turn the control to find the feedback problem area. This subtlety turns down a small area of frequencies, thus removing the feedback without greatly affecting the overall sound. Turning this knob full counter-clockwise will defeat the feedback filter.

PLAYBACK VOLUME

This control adjusts the amount of input from the

Playback input jacks (Rear Panel). This set of Stereo RCA jack will accept any Line-Level audio sources such as: CD, MP-3, DVD, HARD DISC & TAPE PLAYER. NOTE: This controls passes signal directly to the MONITOR Master section and is not affected by the Channels ON/MUTE function.

The number values are in dBV (1VRMS = 0dBV).

LIMITER LED

This indicates Power Amp A has reached full clean output. If the input signal to the power amp increases after the LED is lit, it will be limited to protect the speakers. Because this limiter is built into Power Amp A, the LED only shows that the monitors are at full output when assigned to it (See page 9 for information on assigning power amps).

FAQ Frequently Asked Questions:

1. How many speakers can I use with the KPM8420T?

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 KPM8420T: 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 KPM8420T. 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 KPM8420T?

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.

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 KPM8420T?

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 KPM8420T 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.

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.

6. Can I use another non-powered mixer with my KPM8420T to get more channels?

ANSWER: YES! Take the Line level output of the
