RAM SYSTEM 2000 USER MANUAL Sep 28th, 2018 Rev. 2.0, Firmware version V2.
INSTALLING THE RAM SYSTEM 2000 Thanks for purchasing the RAM System 2000. Please make sure the following items are in the box when you open it. • • • • • This manual. RAM System 2000 main unit. Power Supply labelled HA-PSU03. Bluetooth antenna. IEC Cable. Depending on your system requirements, you will need several TRS cables to hook up your system. Please check your input sources and output destinations and buy the correct cables.
GENERAL DESCRIPTION The Heritage Audio RAM SYSTEM 2000 is a professional monitor controller in a convenient tabletop format. With its matrix of inputs and outputs, covering balanced and unbalanced analog, Spdif digital and the innovative professional quality HA Bluetooth technology, the System 2000 will cover all the monitoring needs of the most demanding professional facilities at a price never heard before.
• BLUETOOTH: This input features the same architecture found in the acclaimed Heritage Audio BT-500. If you are not familiar with it, the BT-500 is an Audio Streaming device in a convenient 500 Series format. It streams audio from your Bluetooth-equipped device and delivers a fully balanced, +22dBu stereo output. Integration of mobile devices intro a professional studio environment has never been easier. More info on the Bluetooth features later.
SIGNAL MONITORING FACILITIES As previously explained, the heart of the RAM System 2000 is its microprocessor controlled, ladder type attenuator. This can be accessed in 2 ways: • • Using the Red Level Knob: As in any traditional monitoring system. Fully clockwise it performs at unity gain (maximum level) whilst reducing it in 1dB steps up to 64. After this the unit turns Mute on.
TALKBACK FACILITIES The RAM System 2000 features talkback facilities in a similar fashion to the large format consoles. Talkback signal can be assigned to the Mix signal (following Input selected), by pressing TB MIX. It can also be assigned to the dedicated CUE input by pressing TB CUE, or at both at the same time, pressing TB ALL. All 3 buttons are momentary (they do not engage), so need to be pressed for the talkback to function. This avoids sending embarrassing comments to the talent by mistake.
UNDERSTANDING THE BLUETOOTH INPUT There is still a popular misconception that Bluetooth is detrimental to the audio quality. Although this has been true in the past, it is no longer the case. Bluetooth is just a “wireless serial port” and, as so, has no ability to interact with your sound quality. However, in order to fit the heavy data traffic that digital audio needs, digital audio compression is applied. This is the real source for audio degradation in Bluetooth connections.
Vast majority of Android devices have already adopted the amazing sounding “Qualcomm® aptX™ audio” Codec **, which is nearly lossless and the standard that wireless high quality headsets and sound bars are adopting. For a complete list of devices currently supporting aptX please visit: http://www.aptx.com/products/browse/categories In case your device can´t support neither AAC nor aptX, the BT-500 will stream audio using the classic SBC codec. (*) Heritage Audio is an official AAC licensee.
OPERATION Whenever a device is paired with the RAM System 2000, the “SYNC” LED will light. From then on, your mobile device takes over the transmission, including Transport control (PLAY, STOP, etc.) and Level (Volume). Active streaming is confirmed by corresponding Codec LED being turned on. Please note Codec IS NOT configurable. It is automatically chosen from the best available option on your mobile device. Devices can only be paired one at a time.
• SHIFT + TB CUE: Raises the talkback mic gain.
