SEND
Run a shielded patch cord from the SEND jack to the INPUT of your effects unit. The output
impedance of the Effects Send Jack is 100 ohms. This jack can be used as a line level output for
use in conjunction with a slave power amp such as SWR's Power 750. It may also be used as an
unbalanced record out.
RECEIVE
Run a shielded patch cord from the Bass 350 RECEIVE jack to the OUTPUT jack of your effects unit.
All patch cords used with effects should be as short as possible and should be routed as direct
as possible. Running patch cables over the top of the Bass 350 (as with any amplifier) can
induce hum in the cables and is not recommended.
A unique feature of the Receive jack is the ability to practice a part along with pre-recorded music.
To accomplish this, insert a tape recorder or other sound source into the Receive jack (make sure
it is a MONO source). Using the Blend control, adjust the level of recorded music from the Receive
to the "live" sound of your instrument. The mixed sound will be heard through your speakers. This
is also an excellent way to practice along with a drum machine.
Input impedance of the Receive jack is 27k ohms minimum.
Note: Inserting a plug into the Receive jack activates the Effects Blend control. The control
receives this command through the ground created by the phone plug making contact with
the jack. The plug must be a mono plug (tip and ground). If you have a stereo plug only, it
will be necessary to tie the ring and the ground together.
SPEAKER JACKS
Two 1/4" phone jacks and two Speakon
the Bass 350 to your speaker system. The minimum load (or impedance) that can be used with
the Bass 350 is 2 ohms total. In other words, you can connect two 4 ohm, four 8 ohm or eight
16 ohm enclosures to the Bass 350. That said, we recommend a total load of 4 ohms for best
performance.
Whenever possible, use the Speakon jacks. Speakon jacks and connectors offer the best possi-
ble connection and are far superior to banana or 1/4" phone jacks in that they not only lock in
place (preventing accidental disconnection), but also offer a greater and more stable connection
surface. This solid connection provides a more effective transfer of power to your speakers.
Only SPEAKER CABLE of 18 gauge or heavier (the heavier the cable, the lower the gauge) should
be used to connect your Bass 350 to your speaker system. Do not use shielded instrument cable
to connect your amplifier to your speaker enclosure, as this can result in intermittent power loss,
cause your amp to oscillate and damage itself and/or your speakers, and render the cable use-
less for any purpose.
Note: Unlike most amplifiers on the market, the Bass 350 can be used for recording pur-
poses without speakers attached to the speaker jacks (using only the XLR Output).
Recommended single SWR Speaker enclosures for use with the Bass 350 include:
• Big Bertha
• Henry the 8x8
• Triad
• Goliath III
• Goliath Junior III
