Introduction

Congratulations and thank you for purchasing PWM-10000Q amplifier. This amplifier
is a representation of PowerStudio’s continuing commitment to produce the best and
highest quality audio products at an affordable price. This amplifier is designed to
provide a big impact in sound reproduction. Please read and understand this manual
completely before attempting to operate your new amplifier. This booklet contains
important information concerning the proper and safe operation of your new amplifier.

Unpacking: Every PWM-10000Q amplifier has been thoroughly tested and

has been shipped in perfect operating condition. Carefully check the shipping carton
for damage that may have occurred during shipping. If the carton appears to be
damaged, carefully inspect your unit for any damage and be sure all accessories
necessary to operate the system have arrived intact. In the event damage has been
found or parts are missing, please contact your dealer for further instructions.

Installation: This amplifier is designed to mount into a standard 19”rack. The

front panel provides four holes used to screw the unit into a rack. The unit also
provides a way to rear mount the unit into a rack for added security. Rear mounting the
unit is especially recommended if the unit is to mount into a mobile rack.

1. Carry/protection handle - Both handles can be used to carry the amplifier, they also act

as protection for the front panel.

2. Front panel fan grill & filters - Detachable snap-in front panel design for the ease of

dust filters replacement (as Figure 1A), foam filters are located behind the front panel to
prevent dust entering the amplifier.

3. Input level attenuators - These controls are used to alter the signal level entering the

amplifier. They are calibrated to help set up active loudspeaker systems or cut down
unwanted noise from the input signal.

4. Clip/limit indicator - This indicator tells when the amplifier output is clipping or limiting.

The two different states can be told apart:

 When the clip limiter is engaged it flickers briefly.

 When the clip limiter is not engaged it lights for a longer period.

5. VHF protect indicator - This indicator lights when constant signals, above 12KHz at full

power, are present at the output terminals. When this happens the input signal is muted
and the process cycles until the VHF signal is no longer present.

6. Over temperature protect indicator - This indicator lights if the amplifier tries to operate

above its maximum operating temperature (90°C). The indicator first comes on as a
warning to either turn down the input level or check the cooling arrangements after which
point the amplifier will mute the input signal. When the cooling fans have returned the
output heatsinks to the normal operating temperature the input signal is unmuted.

7. Mute indicator - This indicator will light when if a fault condition on the channel. The

possible conditions may be due to overload, overheat, CPL and VHF protection.

8. AC Power switch - This is used to activate the amplifier.

2. The DIP - switch features - The following

features may be adjusted using the DIP­switches on the rear panel of the amplifier.

 Gain - Globally set for all channels, from

+23dB to +44dB in 3dB steps.

 Option active - Not currently implemented.

 Fan Masked - When on, engages the

intelligent fan feature; fan speed is lowered
when no signal is present.

 Bridge A+B / Bridge C+D - Switches the channel pairs into bridge mode operation, an

automatic -6dB gain compensation is applied.

 VPL - The Voltage Peak Limiter provides optimum peak voltage settings for each channel.

Level selections vary by model within the PWM-10000Q amplifier.

 Mode - Select VPL mode to either Hard or Soft operation. For channels driving sub-woofers

and low-frequency drivers, it is recommended to use the Hard setting for optimal operation.
For mid-and-high-frequency drivers, always select Soft.

3. Input connectors - This amplifier is equipped with XLR-F input connector.

4. Output connectors - PWM-10000Q offered with Neutrik NL4FC Speakon output connectors.

Operation and Performance

Signal flow blocks

The PWM Series amplifier has the same signal flow, and the same feature sets. The
only internal differences are in the maximum output current per channel and VPL
settings.

The input stage of PWM Series amplifier has a high sensitivity to provide ample
system headroom. This in effect means that the input stage is almost impossible to
clip.

Overall amplifier input gain is adjusted using the input stage DIP-switches. Please
note that the gain setting is global, affecting all channels. Following the input stage,
the dedicated level control on each channel allows signal attenuation from 0 dB to
minus.

The Current Peak Limiter (CPL) section dynamically limits the input signal based on
three parameters: sensed current level, feedback from the output stage, and sensed
voltage clip from the VPL (and output amplifier voltage clip if “Soft Clip” is activated).
This ensures that power output is maintained within the design limits of the amplifier.

The adjustable Voltage Peak Limiter (VPL) sets the maximum output voltage and
therefore also the maximum output power. Eight different voltage stages are
available using the DIP-switches on the rear panel.

The sophisticated output section monitors faults and generates appropriate
warnings, which are displayed on the amplifier front panel. These alerts allow the
operator to adjust system settings and thereby avoid problems. In the rare event that
condition are extraordinarily severe, the amplifier will shut down until the fault or
problem setting ha been rectified or adjusted. These sensing circuits are also
employed to feed back voltage and current level information, via a side chain, to the
limiters. Sensing circuit also transmit local amplifier module temperature and power
supply temperature to the appropriate protection mechanisms. Read the Protection,
Faults and Warnings section for further details.
