These are tested and work well.

The length is the total length of both sides. 20 minutes means 10 minutes per side.

Order custom-made blank CHROME audio cassettes in any length from 1 minute to 110 minutes. These tapes are tabs in or tabs out for recording at home or with professional recording machines. To record on home cassette decks with tabs out shells you can put scotch tape over the record tabs, or disable the sensor inside the cassette deck. It's easy!

These tapes are custom made for your order - most orders are completed and shipped within 5 business days or longer.

Cases, labels, and J-Cards are sold separately.

This item qualifies for BONUS POINTS! Every tape you order earns a bonus point that can be redeemed for discounts on future orders. To redeem the point convert them to a gift certificate.

Please note: we have limited stock of both chrome tape and chrome notch shells, with an inventory of less than 500 units per shell. This is vintage stock, meaning that some shells may be lightly scratched or grungy. As they are custom-loaded with tape, there are no returns of refunds for cosmetic issues such as scratches. In the event that we oversell on shells you will be asked to switch shell color or given the opportunity for a refund.

RACK-UP® SERIES Model RU-MP2 Stereo Mic Preamplifier

ANYWHERE YOU NEED...

· XLR In/Out Stereo Microphone Preamp

· Gain Trim on Both Channels

· Selectable Phantom on Each Input

· Front or Rear Panel Line Level Outputs

· Low Noise Audio Performance

· RF Filtered Inputs

You Need The RU-MP2!

The RU-MP2 is part of the group of RACK-UP products from Radio Design Labs. RACK-UPs feature the

advanced circuitry for which RDL products are known, combined with accessible user-friendly controls

and displays. The ultra compact design permits high-density installations, with three products mounted in

a single rack unit! Single RACK-UPs can be mounted right where they are needed using the adhesive

mounting method popularized by RDL’s STICK-ON“ series of products. Optional brackets permit

mounting a RACK-UP module above, below, or in front of any flat surface!

APPLICATION: The RU-MP2 is the ideal choice where a connectorized mic-to-line audio preamplifier is

needed. This unit features two separate, isolated mic preamplifiers. The RU-MP2 may be used in stereo

applications, or as two individual monaural preamplifiers. Inputs may be strapped to provide phantom

power through the standard XLR connectors. The outputs are low impedance balanced, designed to drive

short or long balanced lines. Outputs are driven through XLR connectors on the front panel, and are also

available on the rear-panel barrier block. When rack-mounted, microphones may be plugged into the

front, while the line-level outputs are hard-wired inside the rack. Both the front panel output XLR

connectors and the rear-panel output terminals are active at all times.

Gain trim is provided for each channel on front panel controls, accommodating a wide variety of dynamic

or condenser microphones. The knurled adjustments are provided with screwdriver slots so the gain trim

may be adjusted by hand or by screwdriver. Audio output connections may be wired unbalanced as

needed in certain systems. The RU-MP2 performance is tailored around industry standard +4 dBu output

levels. Excellent frequency response, phase response, distortion and low noise performance combine to

produce the audio clarity and precision for which RDL products are well known.

XLR input and output connectors are firmly attached to the steel front panel for superior mechanical

integrity. The 24 Vdc power supply input is provided on full-size barrier block connections on the rear

panel. The RU-MP2 may be operated on 12 Vdc with a decrease in headroom.

When a single or dual channel, connectorized microphone preamplifier is needed to provide superior

audio clarity, user adjustments, reliability, compactness and unsurpassed versatility, the RU-MP2 is the

ideal choice.

Model RU-MP2

Stereo Mic Preamplifier

AUDIO INPUTS: The + and - balanced audio signals enter the unit through the front panel XLR connectors. Inputs are normally

set up for dynamic mics (no phantom). If phantom power is desired, simply jumper the phantom terminals on the barrier block.

Unbalanced audio may be connected to the + terminal, with the unbalanced shield connected to both the - and ground terminal

(Pin 1).

AUDIO OUTPUTS: The + and - balanced audio signals from the line driver amplifier are brought out to the front panel XLR

connectors. The ground pin (Pin 1) of each of these XLRs is connected to circuit ground. The same signal also feeds the rear

panel barrier block.

PHANTOM VOLTAGE: The RU-MP2 provides filtered phantom voltage at 24 Vdc. (If the module is operated from a lower supply

voltage, then the phantom will be the supply voltage.) If a microphone is used which requires a greater phantom voltage, such as

48 volts, then an external phantom supply may be connected to either or both of the PHANTOM terminals.

Crown Sound Grabber II PZM Condenser Microphone

The Crown Sound Grabber II utilizes the Pressure Zone Microphone technology in which sound waves reinforce themselves in the area nearest a flat surface.

Because of this new technology, Sound Grabber II offers you the opportunity for vast improvement in the quality of your recordings. The Sound Grabber II will pick up sounds at distances you never thought possible and it will pick them up with a clarity that other microphones, because of the limitations of their construction, simply cannot match. The Sound Grabber II does not need to follow the action, since it has a wide-angle pickup pattern. So long as the mic "sees" the sound, in whatever direction or angle, it will pick it up clearly; it does not need to be between you and the other person. Speakers or vocalists can move freely around the Sound Grabber II without their tone quality changing.

Features:

• Ideal for Theater, Conferencing, Houses of worship and Home video
• PZM design makes the sound clearer and more natural
• Ideal for recording conferences, interviews, home videos
• AAA battery powered
• Medium-impedance unbalanced output
• 1/8 in. (3.5 mm) phone connector
