Top ranking choices for B&H customers who searched for generators under $300

The PT-ASG1 from RDL, is a precision analog-audio generator that features a precision audio oscillator, operating at 700MHz. The portable unit is a good choice for applications requiring a stable audio signal source for audio system alignment and testing.

The unit's output is constantly compared against an internal, temperature-stable reference, providing the stable output required for accurate bench-top audio testing. The PT-AMG1 features two outputs, one balanced (selectable between microphone and line level,) the other unbalanced. The balanced outputs are able to maintain consistent level, regardless of impedance.

The unit operates either from two internal 9V batteries, or from an external power supply. Neither is included. When operated from the batteries, a "Low Battery" LED glows steadily when less than one hour operating time remains.

The matchbox-sized NanoLockit from Ambient Recording is a highly accurate and easy-to-use timecode generator which allows you to wirelessly sync timecode and framerate between devices such as DSLRs, film cameras or audio recorders. Synced devices enable you to generate clips that can be quickly auto-conformed in professional editing software, streamlining your post-production workflow.

The NanoLockit lets you generate timecode at all framerates using the built-in Real Time Clock (RTC), or jam-sync other units by feeding in external timecode via the 5-pin LEMO connector. Syncing up is a one button experience as the unit self-configures and the framerate is set automatically when jammed.

Timecode and metadata are transmitted via the proprietary 2.4 GHz, ACN long-range radio network, making the unit compatible with all other ACN Lockit devices. Power is provided externally via the micro-USB port or by the rechargeable battery, which provides 35+ hours of operation on a full charge. With its sturdy aluminum body and locking LEMO connector, the NanoLockit is well equipped to withstand the prolonged rigors of on-set use.

B&H # ATTSDGPN1200 MFR # TSD-GPN1200

The TSD-GPN1200 Sound Masking Generator from Atlas is an analog generator that allows selection between pink or white noise sources. It is equipped with a variable balanced output to match input requirements for equalizers and amplifiers and delivers 4W, 70V output for powering up to six-masking loudspeakers tapped at .5W each.

Featuring a variable hi-cut filter, operating range between 1 kHz and 8 kHz, and a slope of 6 dB per octave, the TSD-GPN1200 supports equalization for most basic sound masking systems. Both outputs may be used simultaneously allowing large zones to be addressed with external equalization and amplification, while a smaller zone is powered by the internal 70.7V amplifier with spectrum control provided by the onboard hi-cut filter. In addition, this unit requires a 24 VDC, 250 mA power supply (sold separately).

The ST-NG1 is a miniature wall and surface mount random noise generator from RDL, suitable as a reference noise source for audio measurements. Additionally, the unit can be used as a masking noise source in engineered sound, or for counter-intelligence applications, particularly where true random noise (occupying the full bandwidth from 20Hz to 20kHz) is required.

The ST-NG1 produces no repetitive frequency or amplitude pattern, unlike digitally-generated pseudo-random noise generators, which can be decoded and removed by effective intelligence equipment. Limiting circuitry controls extreme peak levels in the audio, while still delivering random variations of at least 20dB.

Four outputs provide a microphone-level and line-level output from each noise source, with separate and independent gain-trimming potentiometers provided. Each output is balanced low-impedance, and may be wired either balanced or unbalanced, and all outputs can be used simultaneously.
