PV 1600™
Power Amplifier
Congratulations! You have just taken a giant step forward towards sonic clarity in your sound system. This PV amplifier was
specially designed as an integrated bi-amped power package forming a system with Peavey SP2, SP4 or Impulse 1015
speakers. Not only does it provide the correct amount of power to optimally drive these speaker systems, it also features a
carefully designed electronic crossover and processing section. Using proven technology gained through years of amplifier
design, this unit takes advantage of rugged TO-3P output devices mounted on massive aluminum extrusions and dissipates
heat via an extremely quiet and effective two-speed fan. PV amplifiers employ mammoth toroidal power transformers and offer
impressive specifications and features not found on similarly priced competitive units.
This amp is optimized specifically to drive a pair of SP2s, Impulse 1015s or a single SP4 speaker but will perform well with
similar systems due to similarity of most professional sound drivers. The PV 1600 bi-pack crossover is not just a simple
textbook-style crossover found in most other brands. It has been specially engineered to enhance the inherent response of the
speakers. Instead of having flat looking output curves at tidy 3dB down at the crossover points, this system takes into account
the response of the individual drivers and tailors the electronic curves to sum with the acoustic response to provide a flat
system output.
The crossover points are staggered and the drivers under lapped to provide the most accurate acoustic summing of the two
drivers all through the crossover region. This design approach is somewhat like that of an all-pass Linkwitz-Riley class of
crossover, with the drivers remaining substantially in phase through the crossover region. In this way, the two separate drivers
blend together very smoothly at the crossover, without wild lobes of energy creating hot spots or dead spots.
The high frequency section receives appropriate response shaping to compensate for driver response and constant directivity
horn coverage. A mild bass boost centered around 50 Hz, along with a subsonic (infrasonic) roll off below that, helps avoid very
low frequency overload. In addition to the classic bass boost, a gentle slope throughout the rest of the low frequency range is
incorporated up to the crossover frequency.
PV amplifiers are ruggedly constructed and rack-mountable. Front panel features include calibrated, detented gain (dB) controls
and LED indicators for power (PWR), signal presence (SIG), and DDT® (Distortion Detection Technique) activation on each
channel, as well as a rocker mains POWER switch. The back panel contains an IEC connector for the mains power cord, a mains
circuit breaker with reset, and the critical cooling fan opening. (This opening requires an adequate supply of cool air and should
never be blocked or restricted.) The input section includes a combo XLR / 1/4” phone jack connector, THRU/LOW out and
HIGH out 1/4” jacks. Channel output sections feature dual four-conductor Speakon® connectors. Used with 4 wire Speakon to
Speakon speaker cables, it provides a rugged and foolproof hookup.
Before you begin playing through your amplifier, it is very important to ensure that the product has the proper AC
line voltage supplied. You can find the proper voltage for your amp printed next to the IEC line (power) cord on the
rear panel of the unit. Each product feature is numbered. Refer to the front panel diagram in this manual to locate the
particular features next to its number.
Please read this guide carefully to ensure your personal safety as well as the safety of your amplifier.
