Connecting to your 8-Series Mixer-Recorder

Begin with both the CL-16 and your 8-Series mixer-recorder powered down.

1. Using the supplied USB-A to USB-B cable, connect the 8-Series USB-A port to CL-16 USB-B port
2. Connect the 8-Series’ 1/4" TRS headphone out jack to the CL-16’s 1/4" TRS “To 8-Series Headphone Out” jack using supplied cable.
3. Connect a 10-18 V DC power source using a 4-pin XLR (F) to the DC Input of the CL-16. Power source not included.
4. Power on the 8-Series Mixer-Recorder. Refer to the appropriate 8-Series User Guide for all operating instructions and details.

Powering On/Off

1. Power on the 8-Series Mixer-Recorder. Once the 8-Series has powered up, it will automatically start up the CL-16.
2. To power off, simply flick the 8-Series power toggle switch to the off position. The CL-16 will also power down.

Unplugging CL-16 from the 8-Series

The CL-16 can be plugged/unplugged from the 8-Series while powered on with no damage to either unit. When the CL-16 is unplugged, “Control Surface Unplugged” is displayed in the 8-Series LCD. No levels will change. At this point:

• Expect sudden level changes if Controllers > Soft Fader/Trim Pickup is not enabled as audio levels will now be determined by the trims and faders on the 8-Series.

or

• Reconnect the CL-16. No levels will change unless OK is selected.

Updating CL-16 Firmware

When necessary, CL-16 firmware is automatically updated when updating the 8-Series firmware. The 8-Series PRG firmware update file contains update data for both the 8-Series and the CL-16.

Connect the CL-16 to the 8-Series and ensure both are connected to reliable power sources. Update the 8-Series firmware using the normal procedure. If there is an available CL-16 firmware update, it will automatically start after the 8-Series has completed its update process. The CL-16’s stop button will flash yellow while the CL-16 is updating. Once the CL-16 update has been completed, the 8-Series/CL-16 combo will power on and be ready for us.

Operational Overview

The CL-16 combines the paradigm of a traditional mixer channel strip with the multi-function capability of a modern digital mixer. Once you become familiar with the various controls, different modes, and their associated meter views, the vast potential of your 8-Series mixer-recorder will become apparent. All 8-Series functions (channels, buses, outputs, menus, metadata, coms) can be controlled from the CL-16. Although most of the information is displayed on the CL-16 LCD, the 8-Series LCD still provides useful information when performing some operations (e.g. routing, text entry).

Waveform Display

Overview 

The Waveform Display allows you to see the waveforms of up to 20 different recorded tracks during stop or playback. * Each can be color-customized for ease of viewing and each waveform can be easily PFL’d for isolated analysis. 

To enable the Waveform Display for the CL-16, navigate to Controllers > CL-16 > Waveform Display > Waveform View > Enabled on the 8-Series LCD display. 

With the setting enabled, the main meter view of the CL-16 changes to accommodate the waveform above the meters in the LCD. For faster access, the Waveform View setting has been added as a button-mappable option (Controllers > Mapping). The Waveform Display is only shown while in the Main Home View, and not Bus, Pan, Bank, Dly, HPF, LF, MF, HF, or FAT Channel Views.

*Note: Only waveforms for ISOs 1-16, Bus L, Bus R, Bus 1, and Bus 2 are selectable. 

Selecting Waveforms for Display 

From the 8-Series LCD

Navigate to Controllers > CL-16 > Waveform Display > Waveform Tracks. ISOs 1-16, Bus L, Bus R, Bus 1, and Bus 2 can be selected/deselected for viewing. 

From the CL-16 

With Waveform View enabled, press and hold the Meter button on the CL-16. The upper area of the LCD display changes to show the selectable tracks. 

• If a track is grayed out = deselected 
• If a track has white text = selected 

To select/deselect a track, while continuing to hold Meter press the upper or middle row knob that corresponds to the desired ISO/Bus: 

• Tracks 1-16 = Middle Knobs 1-16 
• Track B1, Track B2 = Upper Knobs 1-2 
• Track L, Track R = Upper Knobs 15-16 

Note: If a track has not been selected, you will not be able to view its waveform. 

Order 

The waveforms are stacked in the following order:

Bus L, Bus R, ISOs 1-16, Bus 1, Bus 2 

Bus L is always on top (the closest), and Bus 2 is always on the bottom (the furthest). 

Waveform Colors

Waveform colors can be selected for each track by navigating to Controllers > CL-16 > Waveform Display > Waveform Colors. This can be used to help identify which waveform belongs to which recorded track. By default, the colors are set as such: 

• L= White  
• R=Red 
• 1-16=Follow Channel Color 
• B1=Lime Green 
• B2=Turquoise 

Setting a track to Follow Channel Color mirrors the color selected from Controllers > CL-16 > Channel Colors. 

Waveform Style

The Waveform Display can be viewed in the following scaling options: 

• Signed 

• Signed (dB) 

• Rectified 

• Rectified (dB) 

Waveform Background

White or black can be chosen as the background color for the Waveform Display by navigating to Controllers > CL-16 > Waveform Display > Waveform Background.

Black

White

Be aware of the following: 

• If the Waveform Background is set to White and a track has its Waveform Color set to Follow Channel Color, if that channel’s color is also set to White the Waveform Color inverts to Black. This is so that it can be seen against the White Waveform Background. 
• If the Waveform Background is set to Black and a track has its Waveform Color set to Follow Channel Color, if that channel’s color is also set to Black the Waveform Color inverts to White. This is so that it can be seen against the Black Waveform Background. 

This is important to know as the default Waveform Color of Bus L is White, making it possible to have two white waveforms. 

Using the Waveform Display 

The Waveform Display analyzes the currently selected take and then displays its waveforms. Waveforms can be viewed while in either the stop, playback, or scrub states. This means you can now navigate the track and add or delete Q Marks while in the stop state. It is recommended when using this feature that any recording media be set to ALL in Track to Media Routing (From the 8-Series LCD: Record Play > Track to Media Routing). While it is possible to use the feature in other configurations, it will take longer to load the waveform if files are spread across multiple folders. 

Notes: Waveform Display is not supported for 32-bit Float files or AAC files.

Isolating Waveforms 

To view a single waveform, simply PFL Channel 1-16 to the left to isolate the desired trace. 

PFL’ing always shows the waveform for a channel, regardless of state of selection in the Waveform Tracks menu. This allows for keeping a less cluttered main view while having access to the waveforms for tracks 1-16 at the flick of a switch. 

Playback with Waveform Display 

While playing back, the timeline of the Waveform Display moves from left to right as indicated by the green cursor. The cursor can be moved either by scrubbing to the desired location or by pressing any of the middle row knobs, which now jump the cursor to the marks indicated just above the Waveform Display: 

• Middle Knob 1 = moves cursor to the start of the take 
• Middle Knobs 2-15 = moves cursor to the center point of the corresponding channel strip 
• Middle Knob 16 = moves the cursor to the last 3/10ths of a second of the take

While stopped or during playback, the cursor is green. While in Scrub mode, the cursor color changes to blue. 

Q Marks 

Q Marks are visible in the Waveform Display as indicated by a red square with a blue outline in the upper portion of the timeline. To assist with navigation, the following shortcuts have been added: 

• Prev Q (Upper Knob 11) = moves the cursor backwards to the closet Q Mark 
• Next Q (Upper Knob 12) = moves the cursor forward to the closet Q Mark 
• Go To Last (Upper Knob 13) = during playback or scrub, moves the cursor back to where it was when playback started.

Shortcuts for Add Q (Upper Knob 5) and Delete Q (Upper Knob 6) have been added to the upper area of the CL-16 LCD while Waveform Display is enabled. 

Scrub/Play 

Shortcuts to Scrub (Upper Knob 15) and Play (Upper Knob 16) have been added in the upper right portion of the CL-16 LCD when Waveform Display is enabled. 

Notes: The CL-16 allows for scrubbing at a speed +/- 32x – which isn’t available in the 8-Series alone. With an attached CL-16 the 8-Series will accommodate this. It is also worth mentioning that audible scrub speeds cap out at +/- 2x.  

Timecode 

Timecode displays in the top middle of the CL-16 while Waveform Display is enabled. In the stopped state, timecode shows current. While in playback, timecode switches to the timecode of the take.

How to Make the CL-16 Feel Like an Analog Mixer

An analog mixer’s channel strip typically includes trim, fader, solo, mute, pan and EQ. The CL-16 has a similar feel with its dedicated faders, trims, solos (PFLs), and mutes. By setting the CL-16 to an EQ mode e.g. LF EQ (Hold Bank then Arm), the channel strip’s upper and middle knob give access to EQ control and provide more of an analog channel strip feel.

GPIO

The CL-16’s 10-pin Phoenix connector labeled Remote provides eight GPIO ports. These can be configured as simple contact-closure inputs, and to drive low current draw components such as LEDs and logic-controlled powered relays. 

CL-16 Remote Pin Functions

• Ground (-): for triggering logic-low connections. 
• 1 - 8: Configurable as inputs or outputs, activate high or low, and assigned a function. 
• +5 V DC: for triggering logic high connections. Supplies 1A at 5V. 

Active High inputs trigger when +5 V is applied. 

Active Low inputs trigger when ground is applied. 

Active High outputs go to 5 V when the mapped function is active. 

Active Low outputs go to ground when the mapped function is active. 

The GPIO lines can supply or sink 10 mA through the series 100-ohm internal resistance. This is not enough to directly drive relays but is enough for driving logic-controlled powered relays. 

GPIO Outputs can be used to drive LEDs with a proper series resistor. Resistor values vary from LED to LED, 470 ohms is a good starting point. 

Although the CL-16 has protection against ESD (static electricity), highly inductive loads (like relays, bells etc.) may require extra diode protection to protect against inductive voltage spikes. Make sure to protect the CL-16 with an anti-parallel diode across the coil of what is being driven.

Servicing Faders

The CL-16 features field-serviceable Penny & Giles faders. The faders can be quickly changed with minimal effort.

Calibrating Faders

Select 8-Series Main Menu > Controllers > CL-16 > Fader Calibration.

When selected, the following popup is displayed:

"Set all CL-16 faders to 0dB positions and press Ok."

When 'Ok' is selected, a command is sent to the CL-16 to perform a fader calibration. If the CL-16 detects that one of its faders is outside of the 0dB acceptable range, the 8-Series displays the following message:

"CL-16 Fader ‘n’ is not at 0dB. Set Fader to 0dB and Retry."   [n= 1-16]

If the CL-16 fader calibration is successful, the 8-Series displays the following message:

"Fader Calibration Success".

If the CL-16 fader calibration fails, the 8-Series displays the following message:

"Fader Calibration Failed".

Note: Fader values are stored within the CL-16.
