Club Red

Club Red PA System Round Five: The Big Yamaha mixer

We started life with an excellent Allen & Heath 24 Channel sound board. But as we were booking bigger and bigger acts we soon realized that we were outgrowing the Allen & Heath.

We needed more channels. Hell, we needed a lot more channels!

We found the perfect board for us in Hollywood. A used Yamaha PM4000 used by a high end mobile production studio that was going digital. For us, a high end old style analog board like the Yamaha PM4000 is perfect. They give exceptional clarity and are super dependable workhorses.

Our BIG YAMAHA has 34 Mono Inputs and 11 Stereo Inputs for a total of 45 Channels. And the 11 Stereo Inputs can be configured as 22 Mono Inputs for certain situations which is the functional equivalent of 54 channels.

Somewhere down the road we might outgrow this board. If so, our board is expandable to 61 inputs with little effort. We haven’t needed to expand it yet, but maybe we will one of these days!

The new digital boards are great, but if they go down, they go all the way down. With the analog boards, you might lose one channel, but the rest of the board will keep working until you fix that one channel. We love the power, range, sound quality and reliability of our Yamaha PM4000.

In all fairness, the new digital boards are much better for national act touring. The big old boards like ours are a nightmare to haul around on a tour! But it’s just right for a fixed installation like Club Red.

KAIZEN, my friends.

Yamaha PM4000 Sound Mixing Board Specs

Four stereo input modules standard; Electronically balanced for both XLR inputs and outputs; All insert In/Out points operate at +4dBu level, This is for optimum compatibility with pro equipment; Continuously variable 50 dB Gain trim, In addition, switchable 30 dB pad let inputs handle any signal; 6-Step LED meters on each input. The LED meters on each input assist correct setup for optimum gain structure; 8 mono auxiliary mixing busses. In addition, two pair of stereo aux mixing busses that can be used as dual mono, for total of 12 auxes; 8 master mute groups; 8 VCA groups: The groups have mute capability and full-length group faders; 8 primary mix busses (“groups”): The mix busses plus a stereo bus which can be “direct assigned” from inputs or from groups; 11 x 8 Mix Matrix; Extensive input-priority: It features “in-place” Cue system, plus Solo mode that mutes other channels; Built-in fixed/variable frequency test oscillator and pink noise source. The oscillator and pink noise source speed setup and overall system troubleshooting; Large, dedicated stereo VU meters. Also, switchable VU meters for other busses (switching conveniently located next to operator); Hundreds of LEDs: The LEDs indicate status, clip levels, and illuminate switches and meters-no lamps to maintain; Extensive internal switches: In addition, jumpers to alter “default” console functions; Lower noise than ever: The PM4000 features superb audiophile quality; Multiple exhaust fans on rear panel, These fans keep circuitry cool for maximum longevity; Dimmer-controlled “LittLites”. The “LittLites” are provided as standard equipment; PW4000 Power Supply. Club Red has two PM4000 Power Supplies, our main supply and a backup power supply so that a blown power supply won’t affect our ability to put on a show. Both Power Supplies includes full-time AC line voltage digital readout and DC output monitor LEDs.
