AKG Acoustics grants a three-year warranty covering material and labor for the following condenser microphones purchased on or after July 1, 2003, including the C 12VR, C414B-ULS, C 414B-TLII, C 426B, Solidtube; C 4500B-BC; C 4000B; C 3000B; C 451B; C 2000B; C 1000S, the C 480B and the Ultra-Linear Series capsules (CK 61, CK 62, CK 63, CK 69), the SE 300B and Blue Line capsules (CK 91, CK 92, CK 93, CK 94, CK 98). This warranty is valid for AKG products purchased within the United States for the

The microphone capsule is shock- mounted with an elastic dual-circuit suspension and is protected by an easily removable wire mesh grille. The smooth triangular shape of the chassis and its soft-touch paint finish makes it comfortable to hold. The lightweight body is made of die-cast zinc alloy and has a black matte finish for minimum reflection and glare. The D 3700M features a modular output system, which allows the microphone to be used with a standard non-switched or with a silent on-off swi

The AS 4+3 has four balanced mic inputs and three unbalanced line inputs, as well as, one balanced line output and one unbalanced record/line output. Each of the four mic inputs have integrated and adjustable compressor/levelers making the AS 4+3 an automatic level control system. The compressor/levelers can help maintain consistent audio level despite various signal strengths that may be present at the microphone inputs. NOM attenuation decreases by 3dB every time the number of in-use mics doub

Front panel controls provide a fine adjustment for an exact match into whatever component follows the AS 8 in the signal chain. Simple, accurate level adjustment is assured by a single front panel knob for each channel, which simultaneously adjusts the input gain and the level of participation in the gain allocation. Individual channel levels can be accurately adjusted by ear, using nothing other than a talker's voice as a sound source. The AS 8 is easily configured for transparent operation in

The Patented Adaptive Proportional Gain* algorithm is a unique process that allocates the gain applied to each channel after comparing the individual channel level with an overall reference level. The reference level is a mix of all active channels, so it automatically adapts to varying background noise levels in the room. The channel with the most signal receives the most gain. In addition to the adaptive gain allocation, the algorithm also provides an "intelligence" that prevents background no

The device is supplied with a clip that fastens it to a belt or guitar strap. It uses a single 9-volt battery, providing an average life of 50 hours. The output of the B 29 L can be switched either to mic or line output level, depending on the downstream requirement. Both inputs to the B 29 L are mini-XLR-F, and the output is a standard XLR-M. The B 29 L effectively makes one output out of two. It is indispensible with small mixers, where it can expand the number of available inputs. In addition

The recovery cycle refreshes the battery pack by charging and discharging cycles to determine the actual capacity and initialize the capacity counter for accurate use time calculation. Other controls include a 3-step LED display showing the charging status. A lockable DC connector on the rear panel of the CU allows the unit to be powered by either an external DC adapter or by the optional PSU 4000 central power supply. Due to the sophisticated charging system, the battery pack can power the HT 4

How to change the sensitivity of the microphone? The circuit design incorporates the facility to increase the nominal sensitivity of the microphone by 10 dB. This basic change to the microphone’s data may be made by the user in the following manner: 1. Open the microphone according to the description in the last paragraph. 2. On the top left corner of the transformer board are three small p. c. board switches placed next to each other. Change all three switches to the opposite position with a sm
