Mono  Subwoofer  - This  operation  is  similar  to  the  Stereo  Subwoofer  operation  but  in  mono.  When  running  subwoofers  it  is  usually 
recommended  to  run  them  in  mono  mode  to  achieve  a  cleaner  tighter  low  end.  This  operation  allows  you  to  run  several  subwoofers 
down to a minimum of 2 ohms. To avoid amplifier  overheating, never run the amplifier  below 2 ohms in this mode. Set up this mode 
as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF” and the mode switch is set to “MONO.” In this 
mode you may use the frequency adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be 
adjusted from 20Hz to 200Hz.
One  Channel  Normal/One  Channel  Subwoofer  (BI-AMP)  - You  may  also  use  your  amp  to  bi-amp  your  system.  You  may  use  one 
side of the amp to power a subwoofer and the other side to power a full range speaker. Follow the set up guides listed above to mix 
and match your operations.
PROTECTION:
Limiter  -  The  V5000plus™  series  comes  with  a  built  in  limiter.  When  the  input  signal  overloads,  the  “CLIP  LED’s”  indicate  a  signal 
overload, at this time, the master volume should be lowered to reduce distortion. If the input gain level is not reduced the built-in lim-
iter  will  activate.  During  signal  overload,  the  limiter  will  reduce  the  input  audio  signal  enough  to  minimize  the  amount  of  clipping.  A 
limiter takes the gain of an overloading signal and reduces it, the reduction in gain reduces distortion that can cause damage to your 
speakers  and  amplifier.  During  normal  operation  below  clipping,  and  momentary  clips  on  peaks,  the  limiter  does  not  affect  the  audio 
signal and is inaudible. It will allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. During exces-
sive  clipping  the  limiter  will  reduce  the  audio  signal  enough  to  minimize  the  amount  of  clipping.  When  the  input  signal  decreases 
enough  that  clipping  ends,  the  limiter  will  deactivate  and  cease  its  gain  reduction.  The  limiter  has  a  fixed  threshold  and  can  not  be 
adjusted. 
Safe Power Levels at Different Output Loads:
8-Ohm  Loads:  The  amplifier  can  operate  at  practically  any  power  level  without  risk  of  overheating.  However,  if  it  is  pushed  hard 
enough to continually light the “CLIP ” indicator, the amplifier’s average output power can reach 150 watts.
4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its maximum long-term power capacity. If it is 
lit about half the time, the amplifier channel will probably go into thermal protection within a few minutes.
2-Ohm  Loads:  Except  for  an  occasional  flash,  keep  the  “CLIP”  indicator  dark  to  avoid  overheating  the  amplifier  channel.  Clipping 
should be kept to a reasonable minimum. An amplifier’s peak current draw at full output power into 2 ohms is several times what the 
“normal ” draw is, but its various protection circuits will prevent this condition lasting more than a minute or two.
Short  Circuit  Protection  - The  V5000plus™  series  amplifiers  all  come  with  built-in  Output  Short 
Circuit  Protects.  The  Output  Short  Circuit  Protection  protects  the  output  devices  of  the  amplifier 
from short circuits and stressful loads. If your speaker lines short, the amplifier automatically detects 
this  problem  and  discontinues  operation  for  that  channel.  If  one  side  of  your  amplifier  becomes 
shorted  and  goes  into  protect  mode,  the  other  side  will  continue  to  operate  normally.  During  short 
circuit  protection,  the  "Clip"  LED  and  “Protect"  LED  will  light  simultaneously  indicating  amplifier 
fault. All channel output  during the “Short Circuit Protection" will be interrupted (i.e. no sound out

put). Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output ter-
minal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usu-
ally be traced to a bad cable or a bad speaker component and is rarely traced to the amplifier itself.
Thermal Protection - Dual variable speed fans on the V5000plus amplifier provide adequate cooling. During low level output the fans 
run  at  normal  speeds.  During  high  output  and  as  heat  raises,  (exceeding  90°C.),  the  fans  will  run  at  higher  speeds  to  aid  the  cooling 
process.  If  the  heatsink  temperature  exceeds  91°C.,  the  amplifier  will  mute  until  the  amplifier  cools  down.  When  the  amplifier  cools 
below  90°C.,  the  amplifier  will  return  to  normal  operations.  Be  sure  not  to  operate  your  amplifier  below  the  minimum  load  ratings  to 
reduce the risk of overheating problems.
Input/Output  Protection  - The  input  circuits  are  isolated  by  10k  resistors.  An  ultrasonic  network  uncouples RF from  the  output  and 
helps keep the amplifier stable with reactive loads.  
Operating  Voltage  (AC  Mains)  -  The  serial  number  label  indicates  the  correct  AC  main  voltage.  Connecting  to  the  wrong  voltage  is 
dangerous  and  may  damage  the  amplifier.  Always  be  sure  the  source  voltage  for  your  areas  matches  the  required  voltage  for  your 
amplifier.
Gain  Controls  -  The  gain  controls  are  located  on  the  front  panel  and  are  calibrated  in  2dB  of  attenuation  from  full  gain.  It  is  best  to 
adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion 
during normal operation. 
AMPLIFIER FEATURES:
THRU - Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the signal source outputs into the 
first amplifier’s input, patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers 
as there is no excessive level loss. Is not affected by crossover setting.
GROUND LIFT SWITCH - Applying or lifting the ground switch will change the level for background noise and hum, if the noise level 
remains the same in either position, it is better to keep the ground lift switch in the ground position. This will eliminate 60Hz cycle hum 
that is sometimes induced when mounting several units in the same rack.
OPERATING VOLTAGE (AC MAINS) - The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage 
is dangerous and may damage the amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to 
adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion 
during normal operation.
LED INDICATORS - Each channel has six LEDS. Four LEDs indicate signal level activity; two green LED and two yellow LED. One red 
LED  indicates  signal  clipping.  One  red  LED  indicates  protections  mode  for  shorts/  overload.  Both  channels  will  also  share  the  center 
green LED that indicate the amplifier operating mode.
FUNCTION INDICATORS - These green LED indicators detail the amplifiers current operating mode (Stereo, Mono, or Bridge).

30  AMP  PLUG: This  unit  comes  with  a  standard  Edison  plug.  You  can  use  this  amplifier  with  the  Edison  plug.  But, to  get  the  most 
power out of the V-5000 Plus, you will have to change the standard Edison plug to 30 Amp plug, make sure you also have a 30 amp 
power supply. This is a fairly simple process. To do this complete the following steps:
1. Be sure the unit is not connected to a power source. 
2. Cut the standard Edison AC plug off the end of the AC cord. With the 30 Amp plug, remove the two phillips screws (B) at the base  
    of the plug and the three phillips screws (A) at the top, between the plug prongs (diagram 17). Cut back the AC cord casing to  
    expose the three (3) cables that make up the AC cord (diagram 17).
3. Cut back the wire casing on all three individual wires.
4. Slide the AC cord through the 30 Amp plug (diagram 18).
5. Once, all three wires are exposed, the green wire is the ground wire (E), the black wire is the negative, and the white wire is the  
    positive. 
6. Unscrew the three phillips screws (D) that surround the 30 Amp plug. The tallest prong (C) which has a number 2 on it, is the ground  
    prong. Insert the ground wire into the wire housing from the bottom and tighten the phillips screw to hold it in (diagram 18). 
7. Insert the black negative wire into wire housing for the copper colored prong, and tighten the phillips screw to secure the wire in  
    place.
8. Lastly, insert the white positive wire into the last wire housing and tighten the phillips screw to secure.
9. Reassemble, the 30 amp plug by replacing the three (3) phillips screws on the top of the plug and the two (2) at the base to close  
    the plug.
