Page 6: Overview
(i.e., with no fan). Remaining true to our longstanding heritage and tradition of tone, as well as listening to what players want, the Subway D-350 is the latest addition to the line. While bearing obvious similarities to the Subway D-800, the D-350 delivers 350 watts RMS into a 4 ohm load, substitutes a bright switch in place of the deep switch, and has no cooling fan - all of this while incorporating modern SW features like a USB charging port. -
Page 7: Overview: Front Panel
REAR VIEW: SUBWAY® D-350™ OVERVIEW: FRONT PANEL The SUBWAY D-350 begins with the front panel input section, which is comprised of the INPUT jack, MUTE switch, ACTIVE/PASSIVE switch, and BRIGHT switch. The INPUT jack feeds a high impedance J-FET input “buffer amplifier” which provides appropriate loading for all active and passive pickups (including most piezo types). -
Page 8: Overview: Rear Panel
D-350 (or any Subway series) bass amp, no speaker load is required. One feature that sets your new SUBWAY D-350 apart from the rest of the market is the inclusion of a studio-grade XLR balanced DIRECT OUTPUT, with a PRE/POST signal routing switch, MIC/LINE level switch, and PIN 1 GROUND LIFT switch. -
Page 9: Front Panel: (Controls & Features)
INPUT JACK This 1/4” (6.35mm) TS (tip-sleeve) jack is the instrument INPUT that feeds the input preamp stage of the SUBWAY D-350. This stage is inherently transparent and directly feeds all remaining circuitry. MUTE SWITCH This switch (and its associated red indicator/tally LED) mutes the audio signal being sent to all outputs for silent tuning with a tuner connected to the instrument cable and then through to the amp’s input. -
Page 10: High Pass Filter
a rising response at higher frequencies, much like the switches found on many popular classic tube amps. Engaging this filter can bring some “shimmer, sizzle, & bite” into the tone and help to open up the top end. HIGH PASS FILTER While not a physical control, it is an important feature in maintaining control over the extreme low end (especially under high drive conditions) by removing non-musical subharmonics. -
Page 11: Low Mid/High Mid Eq Controls
This control is responsible for the level of the signal being sent to the internal power amp and determines the overall playing volume of the SUBWAY D-350. Using the MASTER VOLUME along with the INPUT GAIN control allows optimal control over playing volume. For example, if you are... -
Page 12: Rear Panel: (Controls & Features)
SPEAKER OUTPUTS The SUBWAY D-350 is rated to drive a minimum 4 ohm load, meaning either 2 x 8 ohm cabinets or 1 x 4 ohm cabinet. The amplifier incorporates a pair of speakON™ NL4FC connectors wired in parallel that mate with either NL2MP or NL4MP plugs. -
Page 13: Speaker Impedance
Never connect the speaker output to anything except a speaker. This especially means not to a DI, even a speaker level DI, because the Subway D-350 utilizes a BTL (bridge tied load or “bridged”) output power amplifier. On a bridged amplifier, the minus terminal that is normally at ground is actually a driven output that swings above and below ground at peak currents of up to 20 amps. -
Page 14: Speaker Polarity (Or Phase)
This signal will not be present in the DI output. DIRECT OUTPUT (DI OUT) A feature that sets your new SUBWAY D-350 apart from the rest of the market is the inclusion of a studio-grade XLR balanced direct output. This output is capable of driving balanced analog lines as long as 500 feet, is fully phantom power protected, noise-resistant, and stability compensated for a reliable, low noise floor, high-quality signal. -
Page 15: Di Out Source Switch
DI OUT SOURCE SWITCH This switch selects the signal source routing that is used to derive the direct output signal. In the PRE position, the signal is sourced directly from the input buffer. Muting the amplifier by the front panel mute switch mutes this output to allow for silent tuning. -
Page 16: Discussion About Smps & Class D From The Design Team
DISCUSSION ABOUT SMPS & CLASS D FROM THE DESIGN TEAM QUESTION: What makes this new amplifier so lightweight? ANSWER: This amplifier uses new technology, both an SMPS (Switch Mode 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. - Page 17 QUESTION: How does the SMPS work? ANSWER: Without getting too technical, a switch-mode power supply takes the incoming AC mains (50-60Hz) power, rectifies it to a high voltage direct current (HVDC). This HVDC is then filtered/ stored in the input filter capacitors as reserve energy for discharge as needed into dynamic loads. This HVDC is then chopped/switched at about 100kHz into high voltage, high frequency alternating current (HVHFAC), which is fed through a high frequency transformer which converts the HVHFAC into low voltage, high frequency alternating current (LVHFAC) which is then rectified and filtered into...

Page 18: 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, so it’s necessary to take a deliberate, systematic approach to troubleshooting in order to effectively identify and correct the problem. - Page 19 SYMPTOM: Noise (high-frequency hiss and hash) in audio: If the noise goes away when the instrument cable into the amp is unplugged, the cause of the noise is external to the amp (possibly an active preamp with the treble turned all the way up, a failing battery, or defective onboard preamp).
