IMPORTANT SAFTEY INSTRUCTIONS!

Please read this very carefully before operating this unit

Read ALL instructions carefully before using this unit.

Do not operate this unit near water, in the rain or where there is moisture.

If this warning is ignored a serious electrical shock or death may occur.

Do not attempt to service this unit. No user serviceable parts inside. Refer

servicing to qualified, ISP approved service personnel.

Never remove or defeat the ground connection on the power cord of this

unit.

Care should be taken to avoid spilling any foreign objects or liquid into this

unit.

This active speaker system has a three-channel internal power amplifier

with a heatsink and a fan located inside the speaker for cooling. Air is

drawn in the front grille and hot air is exhausted out of front exhaust ports

behind the grille of the cabinet. Care should be taken to avoid placing this

active speaker in a location where the exhaust ports are obstructed and

does not allow proper cooling of the internal amplifiers. Avoid placing this

system close to other heat sources. The internal heatsink may reach high

temperatures under normal use. Make certain there is proper ventilation for

the speaker when in use.

Do not drive the ProWedge 212 into excessive heavy distortion for an

extended period of time to avoid premature speaker failure.

Failure to follow these instructions may void the warranty.

Caution: Exposure to extremely high noise levels can

cause permanent hearing loss.

The ProWedge 212 system is capable of producing in excess of 137db SPL at 1 meter.

Continued exposure to noise levels in excess of 90db may cause permanent hearing loss.

Below is a chart of the OSHA (Occupational Safety & Health Administration) regulations for

Occupational Noise Exposure. Please note: OSHA requires hearing protection for any

work environment when the sound levels exceed those shown in Table G-16 when

measured on the A scale of a standard sound level meter at slow response.

INTRODUCTION

Thank you for purchasing ISP Technologies ProWedge 212 active speaker system. The

ProWedge 212 is a high output, powered; two-way monitor at home on the loudest stages,

but providing accurate, detailed reproduction.

A 60 x 60 degree constant directivity horn pattern and use of dual woofers results in

controlled dispersion to reduce bleed into adjacent performers spaces, yet reduces the

extreme beaming of important high frequency information found on competing wedges.

The Sleek, modern design can actually be used in 4 different positions: Normal position

with a 40 degree baffle tilt, ‘Longer-throw’ position with a 50 degree baffle tilt, front-fill

position with a vertical baffle orientation, or side-fill position standing on end on top of a

sub. XLR signal and PowerconTM connectors are recessed on the side, with ‘thru’ outputs

for connection to multiple wedges.

The internal amplifier is based on ISP Technologies patent pending D-CAT (Dynamic

Current Amplifier Technology) amplifier technology. The D-CAT technology is capable of

delivering extremely high output current providing an improvement in transient response,

output current and a noticeable improvement in PUNCH. The D-CAT amplifier technology

utilizes a high performance power amplifier driver that reduces parts count and greatly

improves reliability. The D-CAT amplifiers provide improved reliability by including short

circuit and over temperature protection.

The woofer cones are fully waterproofed to survive the elements and abuse. A reinforced,

foam-backed, curved grille provides further protection. The Baltic birch plywood box is

coated with a tough polyurethane finish for durability.

Important Notice!!!

The information in this section has been gathered from engineering data and is for

informational purposes only. None of the information in this section should be used without

first obtaining competent advice with respect to applicability to a given circumstance. None of

the information presented herein is intended as a representation of warranty on the part of

ISP Technologies. Anyone making use of this information assumes all liability arising from

such use.

All information presented in this manual is based upon materials and practices that are most

common to The United States of America and may not directly apply to other countries

because of differing material dimensions, specs, and/or local regulations. Users in outside

countries should consult with appropriate engineering and regulatory authorities for specific

guidelines.

Correct use of all flyware is required for secure system suspension. Careful calculations

should always be performed to ensure that all components are used within their working load

limits before the cabinet suspended. Never exceed the maximum load ratings.

Before hanging any speaker system, always inspect all components for cracks, deformations,

corrosion, missing, loose or damaged parts that could reduce strength and safety of the

cabinet. Do not suspend the cabinet until the proper corrective action has been taken.

ATTACHMENT TO STRUCTURES

A licensed professional engineer must approve the placement and method of attachment to

the structure prior to the installation of any overhead object. The following performance

standards should be provided to the professional engineer for design purposes; Uniform

building code as applicable, Municipal Building code as applicable and Seismic Code as

applicable.

INSPECTION and MAINTENANCE

Suspension systems are comprised of mechanical devices and, as such, they require regular

inspection and routine maintenance to insure proper function ability. Any suspended ISP

Technologies loudspeaker must be inspected for fatigue at least annually. The inspection

shall include a visual survey of all corners and load bearing surfaces for signs of cracking,

water damage, de-lamination, or any other condition that may decrease the strength of the

loudspeaker enclosure.

Flyware that is provided with or for any ISP Technologies loudspeakers must be inspected

for fatigue at least annually. The inspection shall include a visual survey of the material for

signs of corrosion, bending, or any other condition that may decrease the strength of the

fastener.

ISP Technologies is not responsible for the application of its products for any purpose or the

misuse of this information for any purpose. ISP is also not responsible for the abuse of its

products caused by avoiding compliance with inspection and maintenance procedures.

THERMAL CONDITIONS

The ISP ProWedge 212 is capable of producing in excess of 900 watts at full power. This

generates heat that must be dissipated in order to maintain reliability and insure the amplifier

components stay within their operating temperature specs. To accomplish this the amplifier is

mounted on a heatsink that is internal to the cabinet. Airflow is forced through a port near the

internal heatsink.

In addition the amplifiers are thermally protected internally via a thermal switch which will

attenuate the signal 40db if the heatsink temperature exceeds a certain temperature. When

the temperature drops below a certain point, full signal will be restored. Tests have shown

under extreme conditions that cycling will occur approx. (40 sec. ON, 20 sec. OFF)

It should also be noted that a separate internal thermal breaker also protects the power

transformers. If one power transformer temperature reaches a critical point the internal

thermal breaker will open. If this condition occurs simply reduce the signal level of the

system. This will only occur if the ProWedge 212 is continually pushed into heavy distortion.
