Setting Sample Rate

Quartet operates at all standard sample rates between 44.1 kHz and 192 kHz. In most cases, the sample rate is set by the audio application with which Quartet is communicating. For example, when using Quartet with GarageBand, Quartet's sample rate is automatically set to 44.1 kHz, to match the GarageBand song's sample rate. For those audio applications that don't include a sample rate setting, such as iTunes, Quartet's sample rate may be set in Audio MIDI Setup or on the System Setup tab of Maestro 2.

2. Analog Level - Use this menu to select mic, instrument, or line input.

3. Soft Limit - Use this menu to engage Soft Limit. Soft Limit is Apogee's proprietary analog process for taming transients before A/D conversion. By gently rounding transients in a transparent manner, it's possible to maximize level BEFORE the A/D conversion stage.

Soft Limit is most effective with signals with large transients such as drums, percussion and plucked instruments. Soft Limit may not be the appropriate choice for signals such as bass or organ.

1. Input Level - The gain of each input is controlled with these software knobs. The gain level is indicated in the value box below the knob.

2. Analog Input Meter - This meter displays the level of the analog input after A/D conversion.

3. Group On/Off - Use this drop down menu to assign inputs to 1 of 2 groups. When inputs are assigned to a group, the adjustment of any grouped Input Level changes all Input Levels in the group. This is useful when recording stereo sources such as a piano. If a gain offset is present between inputs when a Group is assigned, this offset is preserved.

4. Phase - Check this box to reverse the polarity of the input signal. Under certain circumstances, when two mics are used on one source, reversing the polarity of one mic may result in a fuller sound. For example, when top and bottom mic'ing a snare drum, a fuller sound is obtained when the polarity of the bottom mic is reversed.

5. 48 V / Phantom Power- Engage this button for 48 volts phantom power on the XLR connections. Condenser mics require phantom power to operate.

1. Dim - Click "D" (for Dim) to lower the speaker (or headphone) output level by 15 dB. This function is a convenient way to briefly lower the playback volume in the speakers or headphones in order to hold a conversation without completely muting the output.

Quartet's top panel Touchpads may be set to engage Dim on the Speaker outputs, the headphone outputs or both at the same time. See Device Settings Tab Window.

1. Sum to Mono - Click "Σ" to sum the left and right channels of the speaker (or headphone) outputs to mono. At many points of the production process, this function is useful to check mono compatibility. For example, when recording with a stereo pair of mics, it's always a good idea to sum both channels

Maestro 2 - Apogee Quartet User's Guide

to mono and check for unevenness in the frequency range caused by phase cancellation and reinforcement of particular frequencies. If the sound changes significantly or sounds "hollow" when summed to mono, this may indicate phase issues caused by a less than optimal mic placement. When mixing, it's also a good idea to check mono compatibility. Beyond questions of phase, any masking caused by overlapping frequencies is most easily heard when listening in mono. Try starting a mix with Sum to Mono engaged - once you have something that sounds good, then disengage Sum to Mono and revel at the beautiful stereo mix you've created!

Quartet's top panel Touchpads may be set to engage Sum to Mono on the Speaker outputs, the headphone outputs or both at the same time. See Device Settings Tab Window.

Low Latency Mixing

While recording, if you notice a delay between the moment you play or sing a note and when you hear it in your headphones you are experiencing latency. Maestro's low latency mixer may help and can be configured by clicking the Mixer tab in Maestro.

Quartet Output Routing Mixer System Setup

Maestro Low Latency mixing

A bit of background information concerning latency and computer-based digital recording setups will help you better understand these functions.

When recording with most computer-based digital audio applications, the delay between the input and output of the recording system often disturbs the timing of the musicians performing. This delay, known as latency, means that the musician hears the notes played a few milliseconds after having actually played them. As anyone who has spoken on a phone call with echo knows, relatively short delays can confuse the timing of any conversation, spoken or musical.

Figure A

To illustrate the effect of latency, Figure A depicts the typical signal path of a vocal overdub session. A vocalist sings into a microphone, which is routed to an analog to digital converter, then to the audio software application for recording. In the software application, the vocalist's live signal is mixed with the playback of previously recorded tracks, routed to a digital to analog converter, and finally to the vocalist's headphones. A slight delay accumulates at each conversion stage, while a much greater amount of delay occurs through the software application, resulting in the vocalist hearing his performance in headphones delayed by several milliseconds.

Figure B

By routing the hardware input directly to the hardware output and mixing in playback as shown in Figure B, it's possible to provide the vocalist a headphone monitoring signal with a much shorter delay.

First, the signal being recorded (in this case, a vocal mic) is split just after the A/D stage and routed to both the software application for recording and directly back to the hardware outputs without going through the latency-inducing software. This creates a low latency path from mic to headphones. Next, a stereo mix of playback tracks is routed to the low latency mixer and combined with the hardware input(s). This allows the performer to hear himself while listening to playback tracks without a confusing delay in order to comfortably record overdubs.

Note that the software application's mixer is used to set a stereo mix of playback tracks while the low latency mixer is used to set the balance between the stereo playback mix and the hardware inputs.

Working with the Maestro Mixer

Do I need the Maestro Mixer?

The Maestro mixer serves to provide a low latency monitoring mix while recording. Therefore if you're using Quartet to listen to iTunes or audio from another program, there's no need to use the mixer.. It's possible that the latency of your particular recording system is low enough to be unnoticed. The system latency is determined by the recording software's buffer setting; if your Mac is powerful enough, it's possible to set the buffer to a lower value (shorter latency) without encountering clicks and pops in the audio output. If the latency doesn't pose a problem while recording, there's no need to employ the low latency mixer.

Recording software settings

Before using the Maestro mixer, it's necessary to change a few settings in your recording software.

Software monitoring

Preferences General Audio MIDI Display Score Video Automation Control Surfaces Sharing Devices General I/O Assignments Sample Editor MP3 Reset Nodes Core Audio Enabled System Memory Requirement: 75.0 MB Output Device: Quartet Input Device: Quartet I/O Buffer Size: 64 Samples Resulting Roundtrip Latency: 5.8 ms Recording Delay: 0 Samples Universal Track Node 24-Bit Recording Software Monitoring Independent Monitoring Level for Record Enabled Channel Strips Processing Threads: Automatic Process Buffer Range: Medium ReWire Behavior: Playback Mode (Less CPU Load) Maximum Scrub Speed: Normal Scrub Response: Normal Apply Changes

Because the signal to be recorded is monitored through the Maestro mixer, the outputs of software tracks actively recording should be muted - after all, that's the source of the latency. Most software applications provide an option to turn off software monitoring of recording tracks. In Logic Pro, for example, the software monitoring option is found in the same Audio preferences window used to select Quartet as the hardware device (Logic Pro menu > Preferences > Audio). Uncheck the Software Monitoring box.

Playback mix

In your recording software, set up a mix of all playback tracks and route it to the first pair of outputs. If a master fader controls the global output of the mix, it's suggested to set the fader to 0 dB.

Maestro Output Routing Tab

In the Maestro Output Routing tab, route Mixer 1 (or Mixer 2) to Line 1/2. If Analog Out Format is set to 2 or 3 Speaker Sets, route Mixer to all the analog outputs in use, as shown below.

Now select the desired input (Line, Mic or Instrument) and set the Input Level on the Input tab; the signal should be displayed on both the Mixer Input and Mixer Master meters. If the Mixer Input's Over LED lights, reduce the input gain in Maestro Input tab. If the Mixer Master's Over LEDs light, reduce the Input fader.

Now start playback in your recording software. The playback signal should be displayed on the Software Return and Mixer Master's meters. Use the Software Return and Input faders to establish your desired balance between the input and playback signals. If you've found a good balance but the Mixer Master's Over LEDs light, reduce the Mixer Master fader.
