About This Manual This manual explains the operation and applications of the API MC531 monitor controller. Based on the monster sections found in API consoles, the MC531 provides flexible, high-quality adieu monitor control for most production applications, in a stand-alone configuration.
Important Safety Instructions Please read these instructions Keep this information in a safe place Do not use this device near water Clean only with a dry cloth Do not block any ventilation openings Do not install near any heat sources such as radiators, heat registers, stoves, or other devices that produce heat Do not defeat the safety purpose of the polarized or grounding type AC plug Protect the AC power cord from being walked on or pinched 9.
1.0 Introduction Building on API's rich heritage of building high-quality recording consoles, we introduce the MC531 Monitor Controller. Based on the monitor sections found in API consoles, the MC531 is a flexible, high quality, stereo audio mentor controller, in a stand-alone configuration.
+ Two independent headphone outputs: o ON/off button o LEVEL potentiate o Choice of 2 sources: = Control Room (C/R) source = €UE source « Talk back to headphones o Talk back electric microphone o Talk back GAIN o TALK BACK activation button The MC531 is built to the same exacting build standards as API consoles.
2.0 Input Source Selectors ST-4 ee Five (5) input source selectors provide a choice of seven (7) different audio sources to feed the selected set of monitors. Each input source is buffered with an API 2510 op-amp. Only one source can be selected at a time. The input source selectors are divided into three categories: « Analog (ST-1, ST-2, ST-3) o Digital USB or AES + Consumer 3.5mm MINI plug or Bluetooth (BT) 2.
NOTE: The USB interface uses a USB type-B connector on the rear panel. The USB interface relies on built-in drivers and is compatible with MAC OS and Windows or after.
2.2 Input Source Meter The level of the selected input source is displayed on a high-resolution RMS meter. e -bedbug to +24dBu range « 18-segment LED meter NOTE: Stereo METER outputs connections are provided on the rear panel for interfacing an external meter. 8T4 uss BLUETOOTH ST-5 wii AES A complete set of input source connections are provided on the rear panel of the MC531.
BLUETOOTH STB i Consumer Inputs: ST-5 + BLUETOOTH: Bluetooth antenna @ « MINI: 3.
3.0 Monitor Control Functions The MC531 provides a comprehensive suite of monitor functions and controls. « C/R LEVEL volume potentiate DIM level and activation button Electable APL 2520 or electronically balanced output stage MONO summing button LT and RT mute buttons CUT (mute) button 3.1 Monitor Controls The MC531 monitor controls function as follows: C/R LEVEL (Control Room Level): Controls the output level for the selected monitor system.
MONO: Sums the Left & Right monster output feed to mono. » Illuminates in red when engaged CUT (mute): Cuts the feed to the selected monitor system.
4.0 Monitor Selectors EEK MAIN LR RY; SH The MC531 supports three (3) sets of stereo audio monitors, plus a sub woofer with a programmable link to each stereo pair. Only one set of monitors can be selected at a time. + MAIN: Main control room monitors e ALT 1: Mid-field or near-field control room monitors ¢ ALT 2: Mid-field or near-field control room monitors 4.
*IMPORTANT NOTE: The MC531 does not provide any bass management functions. When engaged, the SUB (sub woofer) output is unfiltered, full-bandwidth mono sum of the left and right monitor outputs. While this output is intended to feed a sub woofer, appropriate external filtration is needed for proper use (not supplied). 4.
SUB OUTPUT: Mono, unfiltered sum of selected Left and Right monitor outputs* Balanced, low-impedance, line-level 3-pin male XLR Pin 1 = Ground, Pin 2 = +, Pin *IMPORTANT NOTE: The MC531 does not provide any bass management functions. When engaged, the SUB (sub woofer) output is unfiltered, full-bandwidth mono sum of the left and right monitor outputs. While this output is intended to feed a sub woofer, appropriate external filtration is needed for proper use (not supplied). 4.
5.0 Headphone Amplifiers The MC531 is equipped with two independent stereo headphone amplifiers, HP-1 and HP-2. The amplifier circuit is the same as found in API consoles such as THE BOX, 1608, 1608-11, and 2448. The MC531 headphone amplifiers are designed for use by the engineer, musicians, and others in the control room.
HP-1 or HP-2: ON/off switch for the headphone amplifiers. + Illuminates in green when engaged 5.2 Headphone Cue Function The headphone amplifiers can be fed from two (2) primary sources, plus talk back when activated: + Control Room Same feed as the monitor outputs + CUE: Assignable input source Any input source can be assign to the CUE feed. Only one input source can be assigned as the CUE SOURCE. To assign an input source as the CUE SOURCE, perform the following steps: 1.
6.0 Rear Panel The rear panel of the MC531 provide a complete set of connections including: Input Source Connectors: Analog (LT and RT), digital, and consumer .
§T-4 : ST-4 + AES: 3-pin female XLR, AESOP standard use » USB: USB type-B connector RES NOTE: The USB interface uses a USB type-B connector on the rear panel. The USB interface relies on built-in drivers and is compatible with MAC OS and Windows or later. BLUETOOTH ST-5 MINI Consumer Inputs: ST-5 + BLUETOOTH: Bluetooth antenna @ « MINI: 3.5mm stereo (TRS) jack for MINI plug 6.
ALT 2 LEFT & RIGHT OUTPUTS: e LT and RT: Left and Right stereo pair + Balanced, low-impedance, line-level e 3-pin male XL's e SUB OUTPUT: Mono, unfiltered sum of selected Left and Right monitor outputs* Balanced, low-impedance, line-level 3-pin male XLR Pin 1 = Ground, Pin 2 = +, Pin *IMPORTANT NOTE: The MC531 does not provide any bass management functions. When engaged, the SUB (sub woofer) output is unfiltered, full-bandwidth mono sum of the left and right monitor outputs.
6.5 Power Supply Connection ARCHES: @® COM The MC531 is powered by an textual DC power supply unit. Ea a=A8 POWER: The main DC power supply unit connection is interfaced with a S=124 single, locking, 6-pin female DIN connector.
