Stereo, Parallel, and Bridge Mono Modes in Amplifiers

One of the most frequent questions we get is the difference between stereo, parallel, and bridge mono modes in Amplifiers

Stereo Operation

Stereo operation mode is the normal, default mode of an amp. This means that the amplifier provides power to two independent channels. Think of it as two amps in one. Many recent amps can even run two different power/resistance ratings on the two channels at the same time. Usually we run two outputs (left and right) from a mixer, into the two amp channels (left and right), and then into two speakers set up in front of an audience, one on the left, one on the right. This enables an audience to enjoy the stereo effects of music.

Parallel Operation

Parallel operation routes an identical audio signal of one amp input into both channels. You use this to route a mono input (like a microphone, or mono output of a mixer) into both channels of an amp. It is the same as using a Y cable to split a mono input into both channels. After the input, the amp acts exactly like a stereo mode amp.

Bridge Mono Operation

Bridge mono mode combines two amp channels into one mono, much more powerful amp channel. This is most often used for subwoofers. Amplifiers have separate stereo and bridged mono power handling specifications. For instance, the Alto MACRO 1400 amp is rated at 310 W at 8 ohms STEREO, and 900 W at 8 ohms BRIDGE MONO. The advantage of bridge mono is that you have a much higher power rating; the disadvantage is that you have only one amp channel.

Connecting speakers to an amp in bridge mono mode is different from stereo mode. Usually you connect a banana plug to the middle two banana outputs. You must also flip the amp into bridge mono mode, using dip switches on the back of your amp. Consult your amp manual for specific directions on your particular model.

Mark Amundson, FOH Tech Editor, Dead at 49

From FOH Mag:

LAS VEGAS — Mark Amundson, the technical editor of FOH, died on Friday, Sept 4 from what appear to be complications after surgery. An autopsy has been requested but not performed at the time of this writing. Mark was not only an integral part of the FOH team, he was a longtime, close friend, a devoted husband, and he was passionate about audio and music in general. He will be missed in ways we can’t even express. Services are planned for Friday Sept. 11 in his hometown of Cambridge, Minn. Fittingly, after a short prayer service, the plan is for lunch and a final jam session in his honor at the local American Legion Hall — a venue where Mark both played and did regular sound gigs.

Direct Pro Audio and Creighton University Ryan Center

Direct Pro Audio has recently completed a sound and master antennae (MATV) system at Creighton University's Wayne and Eileen Ryan Athletic Center and D.J. Sokol Arena.

The Wayne and Eileen Ryan Athletic Center and D.J. Sokol Arena, a 78,134 square-foot facility, houses a gymnasium with seating for 2,950, accommodating women’s basketball and volleyball coaches’ offices, locker rooms, ticket offices, athletic training and meeting rooms, media workrooms and much more. The arena is also expected to be used for other campus and community events including campus assemblies, coaching camps/clinics, concerts, speakers, and high school graduations.

The facility has a number of intended uses:
  • Competition site for women's basketball and volleyball
  • Meeting place for Creighton students, faculty and staff
  • Practice site for men's basketball, women's basketball, volleyball and others
  • Community resource for smaller concerts, speakers and programs
  • Host site for high school basketball games and tournaments
  • Venue for high school graduations.
The sound system, designed by consulting firm Wrightson, Johnson, Haddon & Williams, (W.J.H.W.), consists of 11 Electro-Voice main speakers supplemented with 24 JBL rear fill speakers. Media Matrix NION digital speaker processing and amplification by Crown round out the robust system capable of providing clear direct sound to the entire bowl seating area.

A mobile rack, consisting of a CD player/recorder, MP3 player interface, and Sennheiser EW500 series dual wireless system provide input sources from courtside, or any one of six locations around the arena. A Yamaha LS9 digital console with a Whirlwind E-Snake COBRANET digital audio network provide input and mixing capapilities for 48 sources from anywhere in the arena for special events.

In addition, Direct Pro Audio installed a building sound system matrix for offices, locker, and meeting rooms, complete with inputs for local MP3 and CD players, with local control of audio sources and levels. Tannoy and Atlas speakers round out the system for restrooms, lockers, offices, and concession areas.
