In broadcast facilities and television studios, a central apparatus room (CAR, pronounced "C-A-R"), central machine room, or central equipment room (CER), or central technical area (CTA), or rack room is where shared equipment common to all technical areas is located. Some broadcast facilities have several of these rooms. It should be air-conditioned, however low-noise specifications such as acoustical treatments are optional. Equipment is connected either directly with an attached foldout monitor, keyboard and mouse or remotely via KVM switch, ssh, VNC, RS-232 or remote desktop.

A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right). Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings (called an "mrad/mrad scope"), the shooter can use the reticle as a 'ruler' to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling".

Milliradians are generally used for very small angles, which allows for very accurate mathematical approximations to more easily calculate with direct proportions, back and forth between the angular separation observed in an optic, linear subtension on target, and range. In such applications it is useful to use a unit for target size that is a thousandth of the unit for range, for instance by using the metric units millimeters for target size and meters for range. This coincides with the definition of the milliradian where the arc length is defined as 1/1,000 of the radius. A common adjustment value in firearm sights is 1 cm at 100 meters which equals 10 mm/100 m = 1/10 mrad.

The true definition of a milliradian is based on a unit circle with a radius of one and an arc divided into 1,000 mrad per radian, hence 2,000 π or approximately 6,283.185 milliradians in one turn, and rifle scope adjustments and reticles are calibrated to this definition. There are also other definitions used for land mapping and artillery which are rounded to more easily be divided into smaller parts for use with compasses, which are then often referred to as "mils", "lines", or similar. For instance there are artillery sights and compasses with 6,400 NATO mils, 6,000 Warsaw Pact mils or 6,300 Swedish "streck" per turn instead of 360° or 2π radians, achieving higher resolution than a 360° compass while also being easier to divide into parts than if true milliradians were used.

RNZ National (Māori: Te Reo Irirangi o Aotearoa National), formerly Radio New Zealand National, and known until 2007 as National Radio, is a publicly funded non-commercial New Zealand English-language radio network operated by Radio New Zealand. It specialises in programmes dedicated to news, the arts, music, and New Zealand culture generally, including some material in the Māori language. Historically the programme was broadcast on the (AM) "YA" stations 1YA, 2YA, 3YA and 4YA in the main centres.

In 2013, RNZ National had a 10.3 per cent market share, the highest nationwide and up from 9.1 per cent in 2009. Market share peaked at 11.1 per cent in 2011, probably due to the station's coverage of the Christchurch earthquake. In 2014 493,000 people listened to RNZ National over the course of a week – the second-largest cumulative audience. A 2021 survey estimated 609,800 listeners (13.5% of the 10+ population), Morning Report being the most popular, with 434,000 listeners.

Its sister station is RNZ Concert.
