Aluminum Cases for Broadcast & AV Gear: A Buyer’s Guide

A broadcast company in London was covering a major sporting event at Wembley Stadium. They had 6 camera kits (each containing a broadcast camera, lens, wireless transmitter, and monitor), 4 audio kits (mixers, receivers, microphones), and 2 comms kits — all packed in standard off-the-shelf cases. During load-in, a camera case was dropped from the truck tailgate (1 meter onto the concrete stadium floor). The case landed on its corner, and the aluminum frame bent 5mm. The camera inside shifted, and the lens hood cracked against the case wall. The lens itself was scratched — a $1,200 repair. The camera was out of service for 2 days, and the rental replacement cost £400/day. Total: £2,000. The case was a standard 600×400×300mm flight case with generic foam. The foam cavity was 8mm too large, so the camera shifted on impact. A custom case with a CNC-machined foam cavity that held the camera precisely, reinforced steel corners, and a lens protection tube would have cost £90 more. The £90 “savings” cost £2,000. And that was just one incident — the audio cases had loose connector pins from vibration, and the comms cases had scratched control panels from rubbing. Total damage from one event with standard cases: £4,800. Custom cases would have cost £540 more total. The “savings” cost £4,260.

Broadcast and AV equipment is among the most expensive and fragile cargo in live production. Broadcast cameras cost $10,000-$50,000 each. Cinema lenses cost $5,000-$25,000 each. Audio mixers cost $3,000-$15,000. Wireless microphone systems cost $1,000-$5,000 per channel. All of this equipment gets loaded and unloaded from trucks, rolled across parking lots, stacked in trailers, and handled by venue crew — every single shoot. A custom case isn’t a luxury — it’s the difference between the gear arriving ready to shoot and it arriving in the repair shop. This guide covers how to specify cases for cameras, lenses, audio equipment, comms, and accessories.

What Actually Damages Broadcast & AV Gear in Transit

After building cases for OB trucks, live event production companies, and broadcast rental houses, the damage patterns are consistent:

• Impact damage (36%) — Cases dropped from tailgate height (80-100cm), knocked against door frames, or tossed by venue crew. Broadcast cameras have delicate lens mounts and CCD/CMOS sensors that don’t survive a 1-meter drop without proper foam support. The lens mount can be knocked out of alignment, and the sensor can be damaged by shock
• Vibration damage (24%) — Truck and trailer vibration loosens connector pins, damages fan bearings, and can misalign optical components. Over a 6-hour drive, an audio mixer takes millions of micro-impulses through the case floor. Without proper shock mounting, this vibration transfers directly to the equipment
• Abrasion and scratching (18%) — Equipment scratches if it rubs against the case interior or against other equipment. Lens barrels scratch, camera bodies scuff, and control panels get marked. A scratched lens barrel reduces resale value and looks unprofessional on a rental kit
• Stack pressure damage (12%) — Cases stacked in a trailer. The lid flexes inward and presses on the camera top, control panel, or lens. A 3mm plywood lid flexes 8-12mm under 150kg of stack load — enough to crack a lens hood or bend a control knob
• Connector and cable damage (7%) — Cables rattling around in the case scratch equipment and damage connectors. XLR connectors bend, BNC connectors crack, and cable plugs break. A damaged XLR connector on a $500 microphone cable costs $20 to repair — but it can also damage the microphone’s input jack
• Hardware failure (3%) — Latches break, handles pull off, wheels fail. A case with a broken latch opens in transit, and the equipment is loose in a cargo hold

Equipment-Specific Case Requirements

Broadcast Cameras

• Case type — 2-6 cameras per case, depending on camera size. Small camcorders (PXW-Z280, XF705): 4-6 per case. Medium broadcast cameras (PXW-X500, URSA Broadcast): 2-4 per case. Large studio cameras (HDC-3500, SK-HD1000): 1-2 per case
• Foam cavity — Each camera in its own cavity, CNC-machined to the exact camera profile (with lens and viewfinder attached). The camera should be supported at the body and lens mount, not at the lens or viewfinder. The lens mount is the most fragile part — it needs a support pad that prevents movement
• Lens protection — The lens should be in a recessed area with a protective tube or cap. Don’t let the lens touch the foam — foam can leave residue on the lens barrel. Use a foam ring that supports the lens around the barrel, not on the front element
• Viewfinder protection — The viewfinder (EVF) should be in a recessed area with clearance. The EVF is fragile and expensive — it can crack if the lid presses on it under stack load. Minimum 15mm clearance between the EVF and the lid foam
• Stackable design — Camera cases are always stacked. The case lid should have a recessed area that interlocks with the case bottom. The lid should be reinforced (5mm plywood + ribs) to support 200kg+ stack load. The lid foam should have clearance for the viewfinder — don’t let the lid press on the EVF under stack load
• Accessory compartment — Separate compartment for batteries, media cards, lens cloths, and cables. Don’t pack accessories loose in the camera cavity — they’ll scratch the camera body and lens
• Labeling — Camera numbers silk-screened or engraved on the case exterior and foam cavities. This is critical for fast load-in — crew need to know which camera goes where in the rig
• Casters — 100mm polyurethane, 4 per case, with brakes on 2. A 4-up case with cameras weighs 30-60kg — it needs good casters

Cinema and Broadcast Lenses

• Case type — 2-6 lenses per case, depending on lens size. Prime lenses (24mm, 35mm, 50mm): 4-6 per case. Zoom lenses (24-70mm, 70-200mm): 2-4 per case. Long telephotos (200mm+, 400mm+): 1-2 per case
• Foam cavity — Each lens in its own cavity, with the lens supported at the barrel (not at the front or rear element). The lens should be in a vertical or horizontal position (depending on lens length) with support rings at 2-3 points along the barrel
• Lens cap protection — The front and rear lens caps should be in place, and the foam should have clearance for the caps. Don’t let the foam press on the lens cap — it can pop the cap off and expose the lens element
• Adjustable dividers — For lens cases that will hold different lenses (rental kits), use adjustable padded dividers instead of CNC-machined foam. This allows the case to be reconfigured for different lens sizes. But for dedicated kits (same lenses every time), CNC-machined foam is better — it holds each lens precisely and prevents movement
• Humidity control — Lenses are susceptible to fungus in humid environments. Include a silica gel packet or a reusable desiccant in the lens case. This absorbs moisture and prevents fungus growth on the lens elements

Audio Equipment (Mixers, Receivers, Microphones)

• Case type — Rack case for mixers and receivers (19-inch standard rack), individual foam cavities for microphones. A typical audio kit has 1 mixer (4U), 2-4 wireless receivers (1U each), and 4-8 microphones
• Shock mounting — Essential for audio mixers and receivers. Audio equipment has sensitive connectors and circuit boards that vibrate. A shock-mounted rack frame (4-point or 8-point suspension) isolates the equipment from case vibration. The suspension should have 15-25mm of travel
• Microphone protection — Each microphone in its own foam cavity, with the grille protected by a foam cap or tube. Microphone grilles are delicate — they dent easily. The foam should support the microphone at the body, not at the grille
• Cable management — Internal cable ties or Velcro straps to keep XLR, BNC, and power cables organized. Don’t let cables rattle around inside the case — they’ll damage connectors and scratch the mixer panels. Use cable bags or compartments for cable storage
• Connector protection — XLR and BNC connectors on the mixer rear panel should be protected by a rear access panel or foam cutouts. Don’t let the connectors press against the case wall — they can bend or break
• Antenna protection — Wireless receiver antennas should be removed and stored in a separate compartment, or protected by foam cutouts. Antennas are fragile — they bend easily and can break off at the base

Comms and Intercom Equipment

• Case type — Individual foam cavities for belt packs, base stations, and headsets. A typical comms kit has 1 base station, 4-8 belt packs, 4-8 headsets, and a power supply
• Belt pack protection — Each belt pack in its own foam cavity, with the controls (volume, channel select) in a recessed area. The belt clip should be protected — it can bend if the case is stacked
• Headset protection — Each headset in its own compartment, with the ear cups protected by foam pads. Headset ear cups are fragile — they can crack if pressed. The microphone boom should be in a recessed area with clearance
• Cable management — Comms cables (XLR, 4-pin, 6-pin) should be organized in cable bags or compartments. Don’t let cables tangle — it slows down setup and can damage connectors
• Labeling — Channel numbers on the foam cavities (for belt packs and headsets). This is critical for fast setup — the crew needs to know which belt pack is which channel

Touring Reality: OB Trucks, Venues, and Air Freight

Broadcast and AV equipment sees a rough chain: studio → OB truck → venue → OB truck → studio, or studio → air freight → hotel → venue → air freight → studio. Each step has its own hazards:

• OB truck loading — Cases are stacked in the truck bay, often on their sides (to maximize space). A camera case on its side means the lens mounts bear the weight of the cases above. Use internal dividers or stackable cases
• OB truck transport — Vibration from the truck engine and road. Cases without proper shock mounting transmit vibration directly to the equipment. Over a 4-hour drive, this can loosen connector pins and damage fan bearings
• Venue load-in — Cases are rolled across parking lots, down loading ramps, and across stage floors. Casters must be 100mm polyurethane — small plastic wheels catch on stage floor cracks and carpet seams
• Venue storage — Cases are stored backstage, often in hallways or loading docks. They may be bumped by other equipment, leaned against walls, or used as impromptu tables. Corner protectors aren’t optional
• Air freight — Cases are handled by airport ground crew, who may not be as careful as your crew. Cases are dropped, tossed, and stacked with other cargo. Use ATA-rated cases (Air Transport Association specification 300) for air freight. ATA Category I cases are designed for 100+ round trips as checked baggage
• Return transport — Cases are loaded back onto the truck, often more roughly than the outbound load (crew is tired at the end of a shoot). The case must survive being “tossed” onto the truck

We’ve built cases for OB trucks, live event production companies, and broadcast rental houses. The pattern is always the same: the broadcast equipment is worth 10-50x the cost of the case. A custom case that fits each camera precisely, isolates audio equipment from vibration, and survives being at the bottom of a 200kg stack isn’t an expense — it’s the insurance that keeps the shoot running. A damaged camera doesn’t just cost repair money; it costs a shoot, a rental replacement, and the client’s confidence. Don’t learn that the hard way.
