Page 4: Important Safety Instructions
Make certain grounding conforms with local standards. YOUR AMPLIFIER IS LOUD! EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE! Your MESA/Boogie® Ampli er is a professional instrument. Please treat it with respect and operate it properly. READ AND FOLLOW INSTRUCTIONS OF PROPER USAGE. -
Page 5: Overview
Overview: Congratulations on your choice of the SUBWAY® D-800+™ and welcome to the MESA/Boogie® family! First, we would like to thank you for choosing us as your amplifier company and trusting us to help create your musical voice. This is something we never take for granted and you’ll find that we are here and ready to assist you should you ever need help. - Page 6 verview rOnt anel The SUBWAY D-800+ begins with the front panel input section, which is comprised of the INPUT jack, MUTE switch, ACTIVE/PASSIVE switch, DEEP switch and BRIGHT switch. The INPUT jack feeds a high impedance monolithic J-FET input amplifier which provides appropriate loading to the pickup, and isolates the switching circuitry from the high impedance signal path.

Page 7: Instant Gratification
INSTANT GRATIFICATION The SUBWAY D-800+ is about the easiest amp on the planet to get great sound from… it really is “plug and play”. Start with the MUTE switch down (mute off), the ACTIVE/PASSIVE switch down (passive pickup), VOICING control in the “flat”... -
Page 8: High Pass Filter
HIGH PASS FILTER This control sets the low frequency roll-off point of the amplifier, and is an important feature in maintaining control over the extreme low end, especially under high drive conditions. This precision four pole filter is comprised of two cascaded two pole filters, one fixed with a turnover frequency that is set at approximately 22Hz and a second variable filter that is variable such that the overall low frequency roll-off can be adjusted from 30Hz to 150Hz. -
Page 9: Treble Control
TREBLE CONTROL The TREBLE control determines the amount of high frequencies present in the signal, relative to the rest of the spectrum. High frequencies (>2.5kHz) are responsible for the “bright”, “airy”, “shimmery” character of the tone. This is also an active control with boost and cut, the amount of boost proportional to the clockwise rotation to the right of “flat”... -
Page 10: Iec Power Inlet
IEC POWER INLET This power inlet conforms to the IEC C-14 type standard, and is used with a cordset containing a matching connector, and appropriate plug for the intended country’s AC requirements. The power supply is internally monitored by supervisory protection circuits and thus contains a non-user replaceable fuse that opens in the event of a major failure. -
Page 11: Headphone Output
HEADPHONE OUTPUT The SUBWAY D-800+ includes a 1/4” TRS (tip-ring-sleeve) headphone output jack, which will drive all common headphones and IEM ear pieces between 8 and 32 ohms. It’s advisable to use caution whenever sticking a sound source in your ear, as damaging volume is possible, especially with “bass player accidents” and when volume is factored over a long period of time. -
Page 12: Di Level Switch
DI LEVEL SWITCH This switch selects between sending mic level (about -30dBu) or line level signal (about +4dBu) from the DI OUTPUT jack. Mic level is probably more commonly used when sending a signal to a PA console (though pro consoles can almost always handle line level), and the line level signal is most often used for driving a recording interface (many are set up for line level only) or when using the Subway D-800+ as a preamp and driving an external power amp (with the signal source set to post-eq). - Page 13 PLAYERS NOTES AND REMINDERS PAGE 9...

Page 14: Discussion About Amps & Class D From The Design Team
DISCUSSION ABOUT AMPS & CLASS D FROM THE DESIGN TEAM QUESTION What makes this new amplifier so small and light weight? ANSWER This amplifier uses new technology, both an SMPS (SwitchMode Power Supply) and a CLASS D power amplifier to decrease the size and weight. These designs are carefully implemented and fully tested to insure robust, reliable performance in real world conditions night after night QUESTION How can a light weight amplifier deliver solid bass? I was always told that an amplifier has to be heavy to produce... - Page 15 QUESTION Why is the Class D power amplifier so small and light weight? ANSWER A Class D amplifier operates its output stage non-linearly, meaning that the output devices are switched either fully on or fully off at a switching frequency of about 500kHz. This “cutoff-saturation” switching minimizes waste heat by avoid- ing operation in the wasteful “linear range”, and without the heat, there’s no need for the large, heavy aluminum heatsinks.

Page 16: Troubleshooting
TROUBLESHOOTING In the event that your amplifier appears not to work correctly, often enough the problem is not with the amp, but a related piece of equipment that it’s necessary to take a deliberate, systematic approach to troubleshooting in order to effectively identify and correct the problem. - Page 17 SYMPTOM NOISE (LOW FREQUENCY HUM) IN AUDIO 1. Defective instrument cable or problem with bass wiring (unplug instrument cable from amplifier, if hum goes away, this means that the noise is entering from outside the amplifier. Try known good instrument cable and/or bass) 2.
