through the loop automatically if an effects unit is not plugged in. An additional feature of the effects loop is that the
effects send jack can be used as a post-signal shape, pre-EQ line output. Plugging into the effects return jack will
break the signal path and provides for a pre-EQ line input.

FAN COOLING – A rear-mounted continuously variable-speed 80 mm fan is utilized, allowing for quite operation at
low output levels and greater cooling capacity when playing at high output levels or under high ambient temperature
conditions. Be aware not to block the fan intake area. For this reason, do not operate the NEO-PAK3.5 in its optional
carry bag.

POWER AMPLIFIER – The NEO-PAK 3.5 features a heavy duty, fully protected, all discrete power amplifi er that
uses 8 robust bipolar output transistors mounted on a stout aluminum heatsink. This allows for full power into
real-world reactive loads without activating the amp’s internal protection circuitry or artifi cially limiting output power.
Output is rated at 350 watts into 4 ohms and 225 watts into 8 ohms with excellent overload recovery characteristics.
Driving speaker loads below the amplifi ers rated minimum load (4 ohms) will result in intermittent operation as the
protection circuits are activated.

SPEAKER OUTPUTS – The NEO-PAK 3.5 provides both ¼” and Neutrik Speak-On™ connectors (wired 1+/1-). All
speaker jacks are paralleled. The minimum speaker load is 4 ohms.

POWER SUPPLY – The NEO-PAK 3.5 uses a custom designed ULTRA LIGHT Switch-Mode Power Supply (SMPS)
featuring our unique linear transformer emulation technology to give the same feel to the amplifi er under overdrive
conditions as a traditional heavy transformer does. Combined with our tube preamp stage, the result is uncompro-
mising transient feel and playability. Switch-mode power supplies convert the AC line directly to high voltage DC,
then the precision PWM inverter creates a new AC power signal at a frequency approximately 1000 times higher
than the original wall frequency of 50/60Hz. This new high voltage, high frequency power signal is then fed into a
custom high frequency transformer that steps the voltage back down, a high frequency rectifi er and high ESR fi lter
capacitors fi nish the process off by converting the high frequency AC signal back to the DC voltages that the amplifi -
er’s internal circuitry uses. One advantage of this conversion process is that the DC power supply rails are refreshed
1000 times more often than in traditional linear supplies, thus reducing annoying hum in the audio signal. The power
supply is externally switchable between 115 and 230 volts, especially convenient for our touring customers. Please
be sure the voltage selector switch is set in the in the correct position BEFORE” connecting the amplifi er to AC
mains power!

POWER INPUT – The NEO-PAK 3.5 is shipped from the factory with a standard IEC type power inlet connector and
the appropriate power cable for the market the amplifi er was shipped to. The SMPS is a universal input (115/230
volt, 50/60 Hz) with a voltage selector switch located above the inlet connector. Be sure that this switch is in the cor-
rect position (matching your local power system) BEFORE connecting the NEO-PAK 3.5 to the power source. There
is an AC mains fuse (with a spare fuse included) located in the small slide-out tray on the IEC power inlet connector.
Always replace with the correct value fuse as indicated on the fuse chart located on the back of the amplifi er.

CHASSIS DESIGN – The NEO-PAK 3.5’s ULTRA LIGHT DESIGN utilizes the highest quality aircraft grade, com-
puter machined aluminum chassis. To clean the amplifi er, nothing more than a damp cloth and a little bit of glass
cleaner (like Windex™) should be used. The silver faceplate is a solid piece of 3 mm machined aluminum.

RACK MOUNTING – The NEO-PAK 3.5 is designed to be rack mounted in a standard EIA style 19” equipment rack
or tour-case. Optional rack mounting ears are available from your dealer

GIG-BAG – A custom padded carry bag with shoulder strap is available as an optional accessory from your dealer.
This padded bag is ideal for convenient carrying of the amplifi er. Do not operate the amplifi er inside the carry bag, as
the cooling fan is obstructed and overheating will occur.
